Account of His Majesty's late Ship Royal George. 297 



According to the analysis of Messrs. Gay-Lussac and 

 Thenard, one pound of oil of olives ought to contain : 



Of carbon 0-7721 pound. 



hydrogen at liberty . . O- 1 208 pound. 

 According to the calculation of M. Lavoisier, 



Pounds of Water 

 heated 180". 



For the 0*772 1 pound carbon 55-881 lb?. 



and for the 0- 1 208 pound hydrogen 26-78 lbs. 



Total 82-661 



And according to the calculations of Mr. Crawford, 



For the 0-7721 pound carbon 44-478 lbs. 



and for the 0-1208 pound of hydrogen 49-528 lbs. 



Total 94-006 lbs. 



Accordincr to mv experiments, one pound of refined oil 

 of colsa has^ furnished a sufficiency of heat to raise 93-073 

 pounds of water to 180", and one pound of oil of olives 

 sufficiently to heat 90-439 pounds of the same water. 



It results from all these comparisons, that the estimates 

 of Mr. Crawford agree much better with the results of my 

 experiments than those of M. Lavoisier.

XLVIT. Jn Accojint relative to the SitvMtion of His Ma- 

 jesty's late Ship Royal George, sunk at Spitliead in the 

 Year 1782 ; together ivilh the Valve, and Means of rnising 

 her. By Mr. J. Hicks, of No. 22, Charlotte Street, 

 Rathbone Place. 



It has been conjectured by many, that the Royal George 

 must be nearly covered with sand and mud, and that any 

 attempt to raise her would be fruitless; and also, that in 

 the event of her being raised, the hull and her stores must 

 be so decayed and injured by the length of time she has 

 been sunk, that the produce would not pay for the trouble 

 and expense; which has induced me, at the request of 

 many friends, to give an account of her situation and value, 

 with the expenses of raising her. 



After showing my plan, model, &c. to the Lords of the 

 Admiralty, T received an order on the 6ih of August last, 

 informing me their Lordships had caused dncctions to be 

 given to Admiral Sir Richard Bickerton,Barl. at Portsmouth, 

 to call together a Committee of the most scientific Captains 

 who might be at that port, with the Commissioner, the- 



Master
