“ If this way of Experiment be made for further distances and raisings of the Peece, as high as conveniently may be above the Level, and the distances measured as hath been intimated; and then all Randoms above these likewise tryed and measured, the distance of an Object, to be Shot at, being known, and other necessary cautions, beneath to be mentioned, carefully observ'd, good Gunners may with great confidence undertake to hit the Mark, be the distance what it will, so it exceed not the reach or the Gun. ”

“ On a fit plat-form, place and point the Gun at a Mark, as large as the Bullet, some 50. 60. or more Yards distant, so as the under-side of the Mark may be in the same Level or Line with the under-side of the Cylinder of the Peece. Then, between the Gun and the Mark at several places, place pieces of Canvas, Sheets of Paper pasted together, or the like, upon Stakes fixt in the ground, so as the underside, being level with the Horizon, may just touch the Visual line, that passeth from the Eye to the upper-side of the Mark ”

“ I caused that, which was already there, to be drained away; and then applying the burning Candle to the surface of the dry Earth at the same point, where the Water burned before; the Fumes took fire, and burn'd very bright and vigorous. The Cone of the Flame ascended a foot and a half from the Superficies of the Earth. The Basis of it was of the Compass of a Mans hat about the brims. ”

“ This he thinks is confirm'd by all the Needles and Sea-Compasses, made in several parts of the World, and consequently touched upon several Stones of several Countries, yet all agreeing in this Magnetical Harmony, that they all give the same directions. 2. That having sometimes drawn a Needle, only over the Pole of the Stone, within the Sphere of its vertue, without at all touching the Stone; it hath received the same directive quality from the Stone, as if it had been really toucht upon the Stone it self, though not altogether so strong, as if it had toucht the Stone. ”

“ Experiments for Improving the Art of Gunnery; To find out the Point-blank distance; the Quantity of Powder, for the just Charge of any Peece; and what Gun shoots farthest. An Answer to some Magnetical Inquiries, formery published in these Transactions. ”

“ The Gun is to be pointed, placed, and ordered every time in one and the same place and position, aiming still at the same Mark, or pointing still in the very same Line or Azimuth; that so all the Shot may fall in the same Line, as near as is possible.
5. The Powder must be exactly weigh'd, every time the Peece is charged, left it having been weigh'd long before, the weight may be alter'd; though Experiment may be made with Cartridges and without.
6. The Powder and Bullet is to be rammed home equally at every Shot; though the looser the Powder lye, it fire the better. ”

“ They have Gold and Silver Mines, but dig them not, pretending the danger and trouble in the work, and contenting themselves with the Filings and Dust of Gold, which they gather out of the Mud and Sand of Rivers and Fountains. ”

“ To passe by the Polonie Tree, producing fruit without any blossoms, immediately out of its Trunk, as big as one man can well carry; and that kind of Fig-Tree, that bears Leaves as big as to wrap up a man in, &c. ”

“ Care is to be had, that the Experiments with the Wedge, Tampion, and the like, made for encreasing the force of the Powder, and the fixing of the Peece, do not endanger it.
III.1. The Long Guns are to be made without any Ring about the Muzzle.
The pieces cut of from the Muzzle, to be alwayes laid on the Carriage, when new shots are made, or their weight of Lead in a convenient Figure, that the recoyl may still be the same.
3. The Quantity of Powder, that Shoots furthest in an Ordinary Culverin being known, there needs no Variation of it in the Long one. ”

“ Then take . more than the first Charge, and do all things else as before, and so continue more tryals, increasing still the Quantity of Powder in the same proportion, every new tryal, till you find the increase of the Charge does not make the Peece Shoot further: Only over-Charge not so far, as to endanger the Gun.
5. The right Charge found, the best Random is to be sought by trying all Randoms, by degrees at a time. ”

“ So far this Answerer; whom as we cannot but much commend for his diligence in searching, and frankness of communicating; so we give these particulars to the publick, that further Tryals may be made by others, for more discovery; hoping withall, that the same Inquisitive person, that hath made these returns, will not scruple to add to them the wayes, he uses for infusing that Magnetical vertue into Steel and Needles, without the help of a Load-Stone, spoken of in the end of this his Answer. ”

“ Cubits broad, so that 12 Horses can very conveniently go in front on it; built 215 years before Christ, by the Emperour Pius, a brave and most Warlike Prince, and dispatcht in the space of five years; commonly it is defended by a Million of men. A Pattern of this also was thought fit, to exhibit here, by Figure II. Fig. II. 5. The Channel, that passeth from one extream of China to the other, having some 24 Sluces, to retain water, when tis necessary; a work of incredible industry and extraordinary advantage.
