TABLE D.

Tangent practice with a long 24-Pr. Gun with 1 solid shot and a charge of 8 lb. of powder, or with a long 18-Pr. charge 6 lb., from the maindeck of a Frigate of the first class; the height of the Gun above the surface of the water being 9 ft.

Distance in yards.	Take aim.	Height of parts aimed at.	Point at the undermentioned parts of Frigates of 44 guns.
297	P. B.	..	At part intended to hit.
By using sight parallel to bore.
402		14 ft.	At the level of the quarterdeck, gangway, and forecastle.
508		22	At bulwark rail of quarterdeck, gangway, and forecastle.
614		33	At 4 feet below the centre of mainmast, reckoning from the deck to the mainyard; centre of foremast; 20 feet below crossjack-yard.
720		47	At 13 feet below mainyard; 5 feet below foreyard; 6 feet below crossjack-yard.
790		61	At under part of mainyard; 3 feet below foretop; 2 feet below mizentop.
860		77	At rail of maintop-bulwark; forecap; 5 feet over mizencap.
930		..	Point at part intended to hit.
*By using the line of metal.
1000		35	At 2 feet below half-way from deck to mainyard; 2 feet above half-way from deck to foreyard; centre of mizenmast.
1060		51	At 9 feet below mainyard; under part of foreyard; 1 foot below crossjack-yard.
1120		68	At 3 feet under maintop; rather better than half-way between foretop and forecap; half-way between mizentop and mizencap.
1180		86	At cap of mainmast; 8 feet over forecap; 3 feet under half-way from mizencap to topsail-yard (hoisted).
1240		106	At centre-way between maincap and topmast-crosstrees; 4 feet over foretopsail-yard (hoisted); cap of mizentopmast.
1299		130	At maintopmast cap; 7 feet under head of foretopgallant rigging.
With 2 shot the elevation must be nearly double that which, with 1 shot, and the same charge of powder, produces the same range.
The angles of elevation, corresponding to the ranges, increase, by quarter degrees, from point blank.
*The reason for transferring the sight to the line-of-metal is, obviously, to use the dispart elevation for the purpose of getting a more direct view.
