Barrel Torpedo used at Charleston, made of an ordinary barrel with ends of solid wood; fired by electricity - Chinese Floating Mine

A, Outer shell. B, Air chamber to keep end up. C, Gunpowder. D, Pistol with trigger connected with rod. E, Rod with prongs to catch vessel coming up stream. F, Iron bands with rings. G, Weights anchoring torpedo. - Early Attempts at Maxim Guns
In all probability each barrel of the first gun had to be loaded separately and fired by hand, one after another. In the second case, the eight little cannon are apparently secured to a kind of turntable, to be revolved by hand. - N
- Rough Diagram, showing Comparative Sizes of Famous Ships at Different Periods
The sizes of these ships can only be shown approximately, as in some cases only the length of the keel is known; in others a mean has to be taken between length of keel and length over-all; while in others the authority does not say where the length was measured. H.M.S. Queen Elizabeth—650 feet long, with a beam of 94 feet—is bigger than all the rest put together.Rough Diagram, showing Comparative Sizes of Famous Ships at Different Periods The sizes of these ships can only be shown approximately, as in some cases only the length of the keel is known; in others a mean has to be taken between length of keel and length over-all; while in others the authority does not say where the length was measured.

Observe the horn-like rowlocks and the steer-board The Nydam ship is 75 feet in length, with a beam of 10 feet 6 inches, and had no mast. Both are very flat amidships, and have very fine or sharp ends, but it is evident that in proportion to her length the Gokstadt boat had a much greater beam. - Uniforms of the British Navy - Midshipman, Admiral, Flag-Lieutenant, Secretary (Fleet Paymaster)
- Hero's Engines
One of the early influences of the art of printing was to bring to the notice of some restless minds the writings of Hero and Archimedes. In Hero's Pneumatics, published more than 120 years before Christ, he gives such a clear account of an invention of his own, in which the expansive force of steam was used to give and maintain motion, as to establish thoroughly his right to the basic invention of the steam engine. He described three apparatus that he devised. In one, the currents of air and aqueous vapor rising through a tube from a hollow sphere, containing water, under which a fire is burning, support a ball placed immediately above the tube, and make it seem to dance. In another apparatus, a hollow sphere into which steam has arisen from what we now call a boiler, is supported on a horizontal or vertical axis, and provided with tubes that protrude from the sphere, and are bent at right angles to the radius and also to the pivot. The inner ends of these tubes lie within the sphere, so that the steam passes from the sphere through the tubes. As soon as this happens, the sphere takes up a rapid rotation, that continue so long as the steam continues to escape from the nozzles of the tubes, which point rearwardly. A third apparatus was merely an elaboration of the second, in that the sphere was connected with an altar which supported a large drum on which were figures representing human beings. The fire being lighted, the sphere would soon begin to revolve, and with it the drum; and the figures on it would seem to dance around, above the altar. The invention was probably to impress the people with the idea that the priests were exerting supernatural power. - Swimming Jacket
A comparison between the two sketches over page will, I think, go far to prove me right, since the so-called "Diver's Helmet" is taken from Vegetius' De Re Militari, not published before 1511. The earliest picture of a diving-helmet of this kind I have been able to find is in a German work published in 1500: both are therefore of a later date than the "Swimming Jacket". This "jacket" was intended to be worn as follows: The lower rectangular part was to be placed at the back, the oval portion to the front of the body. When the swimmer wished to remain at the surface he inflated his jacket by means of the tube; when he required to dive out of sight he would let the air out. Look at the position of the buckles and straps in the two drawings and you will see that there is a strong presumption that the later artist deliberately made the alteration in order to support his bogus picture of a diving-helmet. - Divider

The funnel on the poop is presumably the galley funnel, though placed in an unusual position. - Ship of the latter half of the Fifteenth Century
(From an illuminated MS. of 1480) Note the diminutive figure-head, the two shields amidships—probably placed there for decorative purposes, as the ship appears to be "dressed" with many pennons and streamers. The smallness of the tops is unusual, also the square port-hole and the double-gabled cabin. - The measure of a man

- Wreck of the White Ship, 1120
An example of the impossible-ship picture. There were said to be 300 souls on board! Observe the rudder, which proves the date of the original drawing to be much later than 1120—probably 100 or 150 years. - Diver Salving a Gun

A third apparatus [from Hero] was merely an elaboration of the second, in that the sphere was connected with an altar which supported a large drum on which were figures representing human beings. The fire being lighted, the sphere would soon begin to revolve, and with it the drum; and the figures on it would seem to dance around, above the altar.
