My curioftty leading me to inquire what was the 
weight of the fhip, in the condition fhe was at the 
time of bringing her into the dock j for this purpofe 
I procured draughts of the elevation and fedtion, and 
of the plans at the line of floating, and at the pa- 
rallel fections of every foot diftance down to the 
keel. Then, by finding the mean area between every 
two fedfions, I was thereby enabled to come at the 
magnitude of a folid, that would nearly fill the trough 
the fhip made in the water ; and, by increafing this 
magnitude by that of the keel, and fo much of the 
ftern-poft and ftem, as were under water, the cubic 
feet of the fluid difplaced by the fhip were obtained, 
being 54869 and confequently her weight was 
3532091 pounds, or 1576 tons, 16 C. 2 qrs. 3 ib. 
Thefe numbers were not altogether fo eafily come 
at, as they would have been, had the fhip fwam on 
an even keel, her draught of water before being 1 3 
feet 2 inches, and abaft 16 feet 6 inches. However, 
the computation may be efteemed as corredt as the 
nature of the fubjedt would admit ; becaufe I found 
pretty near the fame folidity by another method. 
I got a block or model made, by a fcale of a quar- 
ter of an inch to a foot, of fo much of the Royal 
William’s body, as was immerged, when flie was 
brought into dock ; and this block I immerfed in a 
trough of fea- water, and found its weight in the 
following manner. 
The length of the trough was 46 inches, breadth 
14 inches, and depth 8 inches : at each corner was 
a graduated fcale of inches, and pencil-lines drawn 
round the infide of the trough at every inch. Sea- 
water was poured into the trough to the height of 5 
inches $
