1 SEveral sorts of Seals, some shewing by scrues, others by gages, fastening or un­fastening all the marks at once; others by ad­ditional [Page 2] points and ima­ginary places, propor­tionable to ordinary Es­cocheons and Seals at Arms, each way pal­pably and punctually setting down (yet pri­vate from all others, but the Owner, and by his assent) the day of the Moneth, the day of the Week, the Moneth of the Year, the Year of our Lord, the Names of the Witnesses, and the individual place where any thing was sealed, though in ten thousand [Page 3] several places, together with the very number of lines contained in a Contract, whereby fal­sification may be disco­vered, and manifestly proved, being upon good grounds suspected.

Upon any of these Seals a man may keep Accompts of Receipts and Disbursments from one Farthing to an hundred millions, pun­ctually shewing each pound, shilling, peny or farthing.

By these seals like­wise [Page 4] any Letter, though written but in English, may be read and under­stood in eight several languages, and in Eng­lish it self to clean con­trary and different sense, unknown to any but the Correspondent, and not to be read or un­derstood by him nei­ther, if opened before it arrive unto him; so that neither Threats, nor hopes of Reward, can make him reveal the secret, the Letter ha­ving been intercepted, [Page 5] and first opened by the Enemy.

2 How ten thousand Persons may use these seals to all and every of the purposes aforesaid, and yet keep their se­crets from any but whom they please.

3 A Cypher and Cha­racter so contrived, that one line, without re­turns and circumflexes, stands for each and eve­ry of the 24. letters; and as ready to be made for the one letter as the o­ther.

4 This Invention refi­ned, and so abreviated that a point onely shew­eth distinctly and signi­ficantly any of the 24. letters; and these very points to be made with two pens, so that no time will be lost, but as one finger riseth the o­ther may make the fol­lowing letter, never clogging the memory with several figures for words, and combinati­on of letters; which with ease, and void of confusion, are thus spee­dily [Page 7] and punctually, let­ter for letter, set down by naked and not mul­tiplied points. And no­thing can be less then a point, the Mathemati­cal definition of being Cujus pars nulla. And of a motion no swifter imaginable then Semi­quavers or Releshes, yet applicable to this man­ner of writing.

5 A way by a Circular motion, either along a Rule or Ring-wise, to vary any Alphabet, even this of Points, so that [Page 8] the self-same Point in­dividually placed, with­out the least additional mark or variation of place, shall stand for all the 24. letters, and not for the same letter twice in ten sheets writing; yet as easily and certain­ly read and known, as if it stood but for one and the self-same letter con­stantly signified.

6 How at a Window, as far as Eye can disco­ver black from white, a man may hold discourse with his Correspondent, [Page 9] without noise made or notice taken; being, ac­cording to occasion gi­ven and means afforded, Exre natâ, and no need of Provision before­hand; though much better if foreseen, and means prepared for it, and a premeditated course taken by mutual consent of parties.

7 A way to do it by night as well as by day, though as dark as Pitch is black.

8 A way how to level and shoot Cannon by [Page 10] night as well as by day, and as directly; with­out a platform or mea­sures taken by day, yet by a plain and infallible rule.

9 An Engine, portable in ones Pocket, which may be carried and fa­stened on the inside of the greatest Ship, Tan­quam aliud agens, and at any appointed minute, though a week after, ei­ther of day or night, it shall irrecoverably sink that Ship.

12 A way to make a Ship not possible to be sunk though shot an hundred times betwixt wind and water by Can­non, and should lose a whole Plank, yet in half an hours time should be [Page 12] made as fit to sail as be­fore.

13 How to make such false Decks as in a mo­ment should kill and take prisoners as many as should board the Ship, without blowing the Decks up, or de­stroying them from be­ing reducible, and in a quarrer of an hours time should recover their for­mer shape, and to be made fit for any im­ployment without dis­covering the secret.

14 How to bring a force [Page 13] to weigh up an Anchor, or to do any forcible ex­ploit in the narrowest or lowest room in any Ship, where few hands shall do the work of many; and many hands applicable to the same force, some standing, others sitting, and by virtue of their several helps a great force aug­mented in little room, as effectual as if there were sufficient space to go about with an Axle-tree, and work far from the Centre.

15 A way how to make a Boat work it self a­gainst Wind and Tide, yea both without the help of man or beast; yet so that the Wind or Tide, though directly opposite, shall force the Ship or Boat against it self; and in no point of the Compass, but it shall be as effectual, as if the wind were in the Pupp, or the stream actually with the course it is to steer, according to which the Oars shall row, and necessary mo­tions [Page 15] work and move towards the desired Port or point of the Com­pass.

16 How to make a Sea-castle or Fortification Cannon-proof, and ca­pable of a thousand men, yet sailable at plea­sure to defend a passage, or in an hours time to divide it self into three Ships as fit and trimm'd to sail as before: And even whilest it is a Fort or Castle they shall be unanimously steered, and effectually be driven [Page 16] by an indifferent strong wind.

17 How to make upon the Thames a floting Garden of pleasure, with Trees, Flowers, Ban­quetting-Houses, and Fountains, Stews for all kind of fishes, a reserve for Snow to keep Wine in, delicate Bathing-places, and the like; with musick made with Mills: and all in the middest of the stream, where it is most rapid.

18 An Artificial Foun­tain to be turned like an [Page 17] Hour-glass by a child in the twinkling of an eye, it holding great quanti­ty of water, and of force sufficient to make snow, ice and thunder, with a chirping and singing of birds, and shewing of several shapes and ef­fects usual to Fountains of pleasure.

19 A little Engine with­in a Coach, whereby a child may stop it, and secure all persons with­in it, and the Coach­man himself, though the horses be never so [Page 18] unruly in a full career; a child being sufficiently capable to loosen them in what posture soever they should have put themselves, turning ne­ver so short; for a child can do it in the twink­ling of an eye.

20 How to bring up wa­ter Balance-wise, so that as little weight or force as will turn a Balance will be onely needful, more then the weight of the water within the Buckets, which counter­poised emty themselves [Page 19] one into the other, the uppermost yielding its water (how great a quantity soever it holds) at the self-same time the lowermost taketh it in, though it be an hundred fathom high.

21 How to raise water constantly with two Buckets onely day and night, without any o­ther force then its own motion, using not so much as any force, wheel or sucker, nor more pul­lies then one, on which the cord or chain rolleth [Page 20] with a Bucket fastened at each end. This, I con­fess, I have seen and learned of the great Ma­thematician Claudius his studies at Rome, he ha­ving made a Present thereof unto a Cardi­nal; and I desire not to own any other mens In­ventions, but if I set down any, to nominate likewise the Inventor.

22 To make a River in a Garden to ebbe and flow constantly, though twenty foot over, with a childs force, in some [Page 21] private room or place out of sight, and a com­petent distance from it.

23 To set a Clock in a Castle, the water filling the Trenches about it; it shall shew by ebbing and flowing the Hours, Minutes and Seconds, and all the comprehen­sible motions of the Heavens, and Counter­libation of the Earth, according to Copernicus.

24 How to increase the strength of a Spring to such an height, as to shoot Bumbasses and [Page 22] Bullets of an hundred pound weight a Steeple-height, and a quarter of a mile off and more, Stone-bow-wise, admi­rable for Fire-works and astonishing of besieged Cities, when without warning given by noise they find themselves so forcibly and dangerous­ly surprised.

25 How to make a Weight that cannot take up an hundred pound, and yet shall take up two hundred pound, and at the self-same di­stance [Page 23] from the Centre; and so proportionably to millions of pounds.

26 To raise weight as well and as forcibly with the drawing back of the Lever, as with the thrusting it for­wards; and by that means to lose no time in motion or strength. This I saw in the Arcenal at Venice.

27 A way to remove to and fro huge weights with a most inconsider­able strength from place to place. For example, [Page 24] Ten Tunne with ten pounds, and less; the said ten pounds not to fall lower then it makes the ten Tunne to ad­vance or retreat upon a Level.

28 A Bridge portable in a Cart with six horses, which in a few hours time may be placed over a River half a mile broad, whereon with much expedition may be transported Horse, Foot and Cannon.

29 A portable Fortifica­tion able to contain five [Page 25] hundred fighting men, and yet in six hours time may be set up, and made Cannon-proof, upon the side of a River or Pass, with Cannon mounted upon it, and as complete as a regular Fortificati­on, with Half-moons and Counter-scarps.

30 A way in one nights time to raise a Bulwork twenty or thirty foot high, Cannon-proof, and Cannon mounted upon it, with men to overlook, command and batter a Towne; for [Page 26] though it contain but four Pieces, they shall be able to discharge two hundred Bullets each hour.

31 A way how safely and speedily to make an approach to a Castle or Town-wall, and over the very Ditch at Noon-day.

32 How to compose an universal Character me­thodical and easie to be written, yet intelligible in any Language; so that if an English-man write it in English, a [Page 27] French-man, Italian, Spaniard, Irish, Welsh, being Scholars; yea, Grecian or Hebritian shall as perfectly under­stand it in their owne Tongue, as if they were perfect English, distin­guishing the Verbs from Nouns, the Numbers, Tenses and Cases as pro­perly expressed in their own Language as it was written in English.

33 To write with a Nee­dle and Thred, white, or any colour upon white, or any other co­lour, [Page 28] so that one stitch shall significantly shew any letter, and as readily and as easily shew the one letter as the other, and fit for any Lan­guage.

34 To write by a knot­ted Silk string, so that every knot shall signifie any letter with Comma, Full point, or Interro­gation, and as legible as with Pen and Ink upon white Paper.

By these three Senses as perfectly, distinctly and unconfusedly, yea as readily as by the sight.

43 How to vary each of these, so that ten thou­sand may know them, and yet keep the under­standing part from any but their Correspon­dent.

44 To make a Key of a Chamber door, which to your sight hath its Wards and Rose-pipe but Paper-thick, and yet at pleasure in a minute of an hour shall become a perfect Pistol, capable to shoot through a Brest-plate commonly of Carabine-proof, with Prime, Powder and Fire­lock, undiscoverable in a strangers hand.

45 How to light a Fire and a Candle at what hour of the night one awaketh, without rising [Page 31] or putting ones hand out of the bed. And the same thing becomes a serviceable Pistol at plea­sure; yet by a stranger, not knowing the secret, seemeth but a dexterous Tinder-box.

46 How to make an ar­tificial Bird to fly which way and as long as one pleaseth, by or against the wind, sometimes chirping, other times hovering, still tending the way it is designed for.

47 To make a Ball of a­ny [Page 30] [...] [Page 31] [...] [Page 32] metal, which thrown into a Pool or Pail of water shall presently rise from the bottom, and constantly shew by the superficies of the water the hour of the day or night, never rising more out of the water then just to the minute it sheweth of each quarter of the hour; and if by fo [...]ce kept under water, yet the time is not lost, but recovered as soon as it is permitted to rise to the superficies of the wa­ter.

48 A scrued Ascent, in­stead of Stairs, with fit landing places to the best Chambers of each Story, with Back-stairs within the Noell of it, convenient for Servants to pass up and down to the inward Rooms of them unseen and pri­vate.

49 A portable Engine, in way of a Tobacco-tongs, whereby a man may get over a wall, or get up again being come down, finding the coast proving unsecure unto him.

50 A complete light por­table Ladder, which ta­ken out of ones Pocket, may be by himself fa­stened an hundred foot high to get up by from the ground.

51 A Rule of Gradation, which with ease and method reduceth all things to a private cor­respondence, most use­ful for secret Intelli­gence.

52 How to signifie words and a perfect Discourse by jangling of Bells of any Parish-Church, or [Page 35] by any Musical Instru­ment within hearing, in a seeming way of tuning it; or of an unskilful beginner.

53 A way how to make hollow and cover a Wa­ter-scrue as big and as long as one pleaseth in an easie and cheap way.

54 How to make a Wa­ter-scrue tite, and yet transparent, and free from breaking; but so clear, that one may pal­pably see the water or any heavy thing how and why it is mounted by turning.

55 A double Water-scrue, the innermost to mount the water, and the outermost for it to descend more in num­ber of threds, and con­sequently in quantity of water, though much shorter then the inner­most scrue, by which the water ascendeth, a most extraordinary help for the turning of the scrue to make the wa­ter rise.

56 To provide and make that all the Weights of the descending side of a [Page 37] Wheel shall be perpetu­ally further from the Centre, then those of the mounting side, and yet equal in number and heft to the one side as the other. A most incredible thing, if not seen, but tried before the late King (of blessed memory) in the Tower, by my directions, two Extraordinary Embassa­dors accompanying His Majesty, and the Duke of Richmond and Duke Hamilton, with most of the Court, attending [Page 38] Him. The Wheel was 14. Foot over, and 40. Weights of 50. pounds apiece. Sir William Bal­fore, then Lieutenant of the Tower, can justifie it, with several others. They all saw, that no sooner these great Weights passed the Dia­meter-line of the lower side, but they hung a foot further from the Centre, nor no sooner passed the Diameter-line of the upper side, but they hung a foot nearer. Be pleased to judge the consequence.

57 An ebbing and flow­ing Water-work in two Vessels, into either of which the water stand­ing at a level, if a Globe be cast in, instead of ri­sing it presently ebbeth, and so remaineth untill a like Globe be cast into the other Vessel, which the water is no sooner sensible of, but that Vessel presently ebbeth, and the other floweth, and so continueth eb­bing and flowing untill one or both of the Globes be taken out, [Page 40] working some little ef­fect besides its own mo­tion, without the help of any man within sight or hearing: But if ei­ther of the Globes be ta­ken out with ever so swift or easie a motion, at the very instant the ebbing and flowing cea­seth; for if during the ebbing you take out the Globe, the water of that Vessel presently return­eth to flow, and never ebbeth after, untill the Globe be returned into it, and then the motion [Page 41] beginneth as before.

58 How to make a Pistol to discharge a dozen times with one loading, and without so much as once new Priming re­quisite, or to change it out of one hand into the other, or stop ones horse.

59 Another way as fast and effectual, but more proper for Carabines.

60 A way with a Flask appropriated unto it, which will furnish ei­ther Pistol or Carabine with a dozen Charges in three minutes time, [Page 42] to do the whole execu­tion of a dozen shots, as soon as one pleaseth, pro­portionably.

61 A third way, and par­ticular for Musquets, without taking them from their Rests to charge or prime, to a like execution, and as fast as the Flask, the Musquet containing but one Charge at a time.

62 A way for a Harque­buss, a Crock, or Ship­musquet, six upon a Carriage, shooting with such expedition, as with­out [Page 43] danger one may charge, level, and dis­charge them sixty times in a minute of an hour, two or three together.

63 A sixth way, most ex­cellent for Sakers, dif­fering from the other, yet as swift.

64 A seventh, tried and approved before the late King (of ever blessed memory) and an hun­dred Lords and Com­mons, in a Cannon of 8. inches half quarter, to shoot Bullets of 64. pounds weight, and 24. [Page 44] pounds of pouder, twen­ty times in six minutes; so clear from danger, that after all were dis­charged, a Pound of Butter did not melt be­ing laid upon the Can­non-britch, nor the green Oile discoloured that was first anointed and used between the Barrel thereof, and the Engine, having never in it, nor within six foot, but one charge at a time.

65 A way that one man in the Cabin may go­vern the whole side of [Page 45] Ship-musquets, to the number (if need require) of 2. or 3000. shots.

66 A way that against several Advenues to a Fort or Castle, one man may charge fifty Can­nons playing, and stop­ping when he pleaseth, though out of sight of the Cannon.

67 A rare way likewise for Musquettoons fast­ned to the Pummel of of the Saddle, so that a Common Trooper can­not misse to charge them, with twenty or [Page 46] thirty Bullets at a time, even in full career.

When first I gave my thoughts to make Guns shoot often, I thought there had been but one onely exquisite way inventible, yet by several trials and much charge I have perfectly tried all these.

68 An admirable and most forcible way to drive up water by fire, not by drawing or suck­ing it upwards, for that must be as the Philoso­pher calleth it, Intra [Page 47] sphaeram activitatis, which is but at such a distance. But this way hath no Bounder, if the Vessels be strong enough; for I have taken a piece of a whole Cannon, whereof the end was burst, and filled it three quarters full of water, stopping and scruing up the bro­ken end; as also the Touch-hole; and ma­king a constant fire un­der it, within 24. hours it burst and made a great crack: So that ha­ving a way to make [Page 48] my Vessels, so that they are strengthened by the force within them, and the one to fill after the other. I have seen the water run like a con­stant Fountaine-stream forty foot high; one Ves­sel of water rarified by fire driveth up forty of cold water. And a man that tends the work is but to turn two Cocks, that one Vessel of water being consumed, ano­ther begins to force and re-fill with cold water, and so successively, the [Page 49] fire being tended and kept constant, which the self-same Person may likewise abundant­ly perform in the inte­rim between the necessi­ty of turning the said Cocks.

69 A way how a little triangle scrued Key, not weighing a Shilling, shall be capable and strong enough to bolt and unbolt round about a great Chest an hun­dred Bolts through fifty Staples, two in each, with a direct contrary [Page 50] motion, and as many more from both sides and ends, and at the self­same time shall fasten it to the place beyond a mans natural strength to take it away: and in one and the same turn both locketh and open­eth it.

70 A Key with a Rose-turning pipe, and two Roses pierced through endwise the Bit thereof, with several hand somly-contriv'd Wards, which may likewise do the same effects.

71 A Key perfectly square, with a Scrue turning within it, and more con­ceited then any of the rest, and no heavier then the triangle-scrued Key, and doth the same effects.

72 An Escocheon to be placed before any of these Locks with these properties.

1. The owner (though a woman) may with her delicate hand va­ry the wayes of co­ming to open the Lock ten millions of [Page 52] times, beyond the knowledge of the Smith that made it, or of me who invent­ed it.

2. If a stranger open it, it setteth an Alarm a-going, which the stranger cannot stop from running out; and besides, though none should be with­in hearing, yet it catcheth his hand, as a Trap doth a Fox; and though far from maiming him, yet it leaveth such a mark [Page 53] behind it, as will dis­cover him if suspect­ed; the Escocheon or Lock plainly shew­ing what monies he hath taken out of the Box to a farthing, and how many times o­pened since the ow­ner had been in it.

73 A transmittible Galle­ry over any Ditch or Breach in a Town-wall, with a Blinde and Para­pit Cannon-proof.

77 How to make a man [Page 55] to fly; which I have tri­ed with a little Boy of ten years old in a Barn, from one end to the o­ther, on an Hay-mow.

78 A Watch to go con­stantly, and yet needs no other winding from the first setting on the Cord or Chain, unless it be broken, requiring no o­ther care from one then to be now and then con­sulted with concerning the hour of the day or night; and if it be laid by a week together, it will not erre much, but [Page 56] the oftener looked up­on, the more exact it sheweth the time of the day or night.

79 A way to lock all the Boxes of a Cabinet, (though never so many) at one time, which were by particular Keys ap­propriated to each Lock opened severally, and independent the one of the other, as much as concerneth the opening of them, and by these means cannot be left o­pened unawares.

80 How to make a Pi­stol [Page 57] Barrel no thicker then a Shilling, and yet able to endure a Mus­quet proof of Powder and Bullet.

81 A Combe-convey­ance carrying of Letters without suspicion, the head being opened with a Needle-scrue drawing a Spring towards them; the Comb being made but after an usual form carried in ones Pocket.

82 A Knife-Spoon or Fork in an usual por­table Case, may have the like conveyances in their handles.

83 A Rasping-mill for Harts-horn, whereby a child may do the work of half a dozen men, commonly taken up with that work.

84 An Instrument where­by persons ignorant in Arithmetick may per­fectly observe Numera­tions and Substractions of all Summes and Fra­ctions.

85 A little Ball made in the shape of Plum or Pear, being dexterously conveyed or forced into a bodies mouth, shall [Page 59] presently shoot forth such and so many Bolts of each side and at both ends, as without the owners Key can neither be opened or filed off, being made of tempered Steel, and as effectually locked as an Iron Chest.

86 A Chair made a la­mode, and yet a stranger being perswaded to sit down in't, shall have immediately his armes and thighs lock'd up be­yond his own power to loosen them.

87 A Brass Mold to cast [Page 60] Candles, in which a man may make 500. do­zen in a day, and adde an Ingredient to the tallow which will make it cheaper, and yet so that the Candles shall look whiter and last longer.

88 How to make a Bra­zen or Stone-head, in the midst of a great Field or Garden, so artificial and natural, that though a man speak never so soft­ly, and even whispers into the ear thereof, it will presently open its [Page 61] mouth, and resolve the Question in French, La­tine, Welsh, Irish or English, in good terms uttering it out of his mouth, and then shut it untill the next Question be asked.

89 White Silk knotted in the fingers of a Pair of white Gloves, and so contrived without suspi­cion, that playing at Primero at Cards, one may without clogging his memory keep rec­koning of all Sixes, Se­vens and Aces which he hath discarded.

90 A most dexterous Di­cing Box, with holes transparent, after the usual fashion, with a Device so dexterous, that with a knock of it a­gainst the Table the four good Dice are fastened, and it looseneth four false Dice made fit for his purpose.

91 An artificial Horse, with Saddle and Capa­rizons fit for running at the Ring, on which a man being mounted, with his Lance in his hand, he can at plea­sure [Page 63] make him start, and swiftly to run his career, using the decent posture with bon grace, may take the Ring as handsomly, and running as swiftly as if he rode upon a Barbe.

94 A little Engine por­table in ones Pocket, which placed to any door, without any noise, but on crack, openeth any door or gate.

95 A double Cross-bow, neate, handsome and strong, to shoot two Arrows, either together, or one after the other, so immediately that a [Page 65] Deer cannot run two steps but, if he miss of one Arrow, he may be reach'd with the other, whether the Deer run forward, sideward, or start backward.

96 A way to make a Sea-bank so firm and Geo­metrically-strong, that a stream can have no pow­er over it; excellent like­wise to save the Pillar of a Bridge, being far chea­per and stronger then Stone-walls.

97 An Instrument where­by an ignorant person [Page 66] may take any thing in Perspective, as justly, and more then the skil­fullest Painter can do by his eye.

98 An Engine so contri­ved, that working the Primum mobile forward or backward, upward or downward, circularly or corner-wise, to and fro, streight, upright or downright, yet the pre­tended Operation conti­nueth, and advanceth none of the motions above-mentioned, hin­dering, much less stop­ping [Page 67] the other; but una­nimously, and with har­mony agreeing they all augment and contribute strength unto the in­tended work and opera­tion: And therefore I call this A Semi-omnipotent Engine, and do intend that a Model thereof be buried with me.

99 How to make one pound weight to raise an hundred as high as one pound falleth, and yet the hundred pound descending doth what nothing less then one [Page 68] hundred pound can ef­fect.

100 Upon so potent a help as these two last menti­oned Inventions a Wa­terwork is by many years experience and la­bour so advantageously by me contrived, that a Childs force bringeth up an hundred foot high an incredible quantity of water, even two foot Diameter, so naturally, that the work will not be heard even into the next Room; and with so great ease and Geome­trical [Page 69] Symmetry, that though it work day and night from one end of the year to the other, it will not require forty shillings reparation to the whole Engine, nor hinder ones day-work. And I may boldly call it The most stupendious Work in the whole world: not onely with little charge to drein all sorts of Mines, and furnish Ci­ties with water, though never so high seated, as well to keep them sweet, running through seve­ral [Page 70] streets, and so per­forming the work of Scavingers, as well as furnishing the Inhabi­tants with sufficient wa­ter for their private oc­casions; but likewise supplying Rivers with sufficient to maintaine and make them por­table from Towne to Towne, and for the bet­tering of Lands all the way it runs; with ma­ny more advantageous, and yet greater effects of Profit, Admiration and Consequence. So [Page 71] that deservedly I deem this Invention to crown my Labours, to reward my Expences, and make my Thoughts acquiesce in way of further Inven­tions: This making up the whole Century, and preventing any further trouble to the Reader for the present, mean­ing to leave to Poste­rity a Book, wherein under each of these Heads the means to put in execution and visible trial all and every of these Inventions, with [Page 72] the shape and form of all things belonging to them, shall be Printed by Brass-plates.
