THE SPECIFIC HEAT OF BODIES. 573 
was 0°10993. The result of Dulong and Petit 
is 0-11, and that of Regnault 0-114. 
Although, in the above experiments, the quan- 
tities of water and metal were much larger than 
desirable, the coincidence of the results, both 
with themselves, and with those which have been 
arrived at by the expert use of the best of the 
old methods, is such as must, I think, inspire 
confidence in the correctness of the new method. 
Hitherto, I have not made many experiments 
with it besides the foregoing, and those which I 
have incidentally found necessary in the course 
of other investigations. I have not, however, 
thought it right to delay the publication of a 
method which appears to possess eminent advan- 
tages over the old processes for the determination 
of specific heat, and which, in the hands of any 
pains-taking experimenter, would, I doubt not, 
lead to the complete elucidation of the laws of 
a most important branch of physics.
