6. A large train of fine brass battering cannon, 24 pounders.
7. Some cannon of a new invention from 6 to 24 pounders. Their superior excellence consists, first, in their lightness, the 24 pounders not weighing quite 1700 weight, whereas formerly they weighed 5000; the rest are in proportion; and secondly, in the contrivance for leveling them, which is by a screw, instead of beds and coins. This new method is more expeditious, and saves two men to a gun, and is said to be the invention of his Royal Highness the Duke of Cumberland.
8. Brass mortars of thirteen inches diameter, which throw a shell of 300 weight; with a number of smaller mortars, and shells in proportion.
9. A carcase, which they fill at sieges with pitch, tar, and other combustibles to set towns on fire. It is thrown out of an eighteen inch mortar, and will burn two hours where it happens to fall.
10. A Spanish mortar of twelve inches diameter, taken on board a ship in the West Indies.
11. Six French pieces of cannon, six pounders, taken from the rebels at the battle of Culloden, April 16, 1745.
12. A beautiful piece of ordnance, made for King Charles I. when Prince of Wales. It is finely ornamented with emblematical devices, among which is an eagle throwing a thunder bolt in the clouds.
13. A train of field-pieces, called the galloping train, carrying a ball of a pound and half each.
14. A destroying engine, that throws thirty hand granadoes at once, and is fired by a train.
15. A most curious brass cannon made for Prince Henry, the eldest son of King James I. the ornamenting of which is said to have cost 200l.
