And the experiments of thefe cele-

 nitrous acid and quick lime in the ratio 

 of 9\ to 1 , give for the real zero,

Seguin, from the experiments of La- 

 voifier on the combuftion of phofphorus 

 narrated in his Elements of Chemiftry, 

 determines the place of the real zero 

 to be — 842=— 1894§ 



He found, by the experiments of 

 Lavoifier on the combuftion of carbon, 

 that it mould be —1204=— 2709 



And he inferred, from Lavoifier's 

 experiments on the combuilion of hi- 

 drogen gas, that the real zero fliould 

 beat . - - - — 739=— 1662f 



The comparifon of the capacities of 

 water and ice, which, according to the 

 experiments of Kirvvan, are as 1 to 

 0.9, fix the real zero at* - - — 600= — 1350 



Dr., Crawford, from experiments on 

 the combuftion of hidrogen gas, places 1 

 the real zero at f - — 6S0f=— 1532 



GadohVs experiments on the con- 

 verfion of fnow into water, taking the 

 capacity of fnow to that of water as 9 

 to 10 according to Magellan, place the 

 real zero at | - — 649f=— 1461 j

dift'er widely, fible, induce us to conclude that one of Dr. Irvine's fuppofi-

that his theorem is not well founded. The feventh and ninth 

 numbers alfo fliew, that a near approximation to accuracy is
