No. 76. A note of the effects already performed by the engine of war; of which there are 200 engines and 3000 bullets already delivered into the Tower for service.--Cal. State Papers, Dom. Series, 1547–1580. Edited by R. Lemon, F.S.A., 8vo. 1856, page 513. In the Bodleian Library there is a folio volume of the MS. papers of General Mountagu, or the Earl of Sandwich, lettered on the back “Carte Papers, 1604–1684. Letters to Earl of Sandwich, &c. 74,” in which is the following: “Invention for Cannon to doe extraordinary execution. (No. 123.) Canon that shall shute more then 400 paces, a bulett of four fadem longe to destroy the Riggings of any ship, the which bulett must necessarily goe a twart, and cannot come perpendicularly, as other chayne buletts, and other such like, who by that means may misse the intended effect and passe through the cordage or Riggings.” Among the Sloane MSS. in the British Museum is one, No. 2497, with rude drawings of cannon, &c. viz.: a fauconet; a faucon; a minnion; a saker; a demi-culveringe; a culvering; a demi-cannon; a cannon; a cannon-peuterer; a cannon-rial; each with its proper ball, ramrods, &c. Robert Norton, Engineer and Gunner in “The gunners dialogue with the art of great Artillery,” a black letter quarto, accompanying “The Arte of shooting in great ordnance,” by William Bourne, 1643, gives the names, &c. of ordnance, thus:-- Cannon of 8 weighing 8,000 lbs. --〃-- of 7 7,000 Demi-Cannon 6,000 Culvering 4,500 Demi-Culvering 2,500 Saker 1,500 Minion 1,200 Among other inquiries in the course of the dialogue occur the following:--“If you were to make a shot in the night, at a mark showed you in the day, how would you prepare for it?” And:--“How would you make a shot at an enemies light, in a dark night, not having any candle, lanthorn, or other light by you?” David Papillon, in his “Practical Art of Fortification,” 4to. 1645, enumerating the ordnance and ammunition of a garrison, observes:--“for a towne of two English miles circumference, of these sorts, six cannons, six demi-cannons, six long culverins [or double for a sea-port], twentie sacres [or less for a sea-port], and twelve drakes, and one hundred thousand [pounds?] weight of powder.”--P. 97. In “Mathematical Magick,” 1648, Bishop Wilkins incidentally remarks--“the greatest cannon in use, does not carry above 64 pound weight,” page 126. And in the 19th chapter of the same work he states the charge to be 40 lbs. of powder. John Greaves, Geometry Professor of Gresham College, who was born in 1602, and died in October, 1652, made experiments for trying the force of great guns, at Woolwich, 18th of March, 1651, which were published in the 15th volume of the Philosophical Transactions, 1685.
