J 821.] Causes of Calorific Capacity, Latent Heat, Sfc. 97 



N. B. This table, though calculated to hundredths, can hardly 

 be depended on to agree with the preceding nearer than to 

 tenths, which are as near, perhaps, as we can generally depend 

 on our observations in those high temperatures. 



The introduction and titles sufficiently explain the nature and 

 use of the preceding tables ; I shall, therefore, merely illustrate 

 their utility by such examples as offer themselves in the course 

 of the following inquiries. 



In p. 403, vol. i. New Series of the Annals, I have given some 

 formulae for the mixture of equal and unequal portions of the 

 same fluid ; and in pp. 406 and 407, I have also developed my 

 ideas of the causes of what are called " calorific capacity, latent 

 heat, &c." With this simple exposition, it is more than proba- 

 ble I should have rested satisfied, had not my friend the Rev. 

 H. S. Trimmer, struck with the comprehensive simplicity of my 

 views, strongly urged me to turn my attention again to the 

 subject, and to develop my theory a little more in detail. To 

 this gentleman, therefore, and the kind assistance he has pro- 

 mised me at a proper season in the prosecution of the necessary 

 experiments, are the present inquiries chiefly to be attributed. 



My object in this paper is to demonstrate, in the usual way 

 of mathematicians, the laws of the phaenomena connected 

 with the hypotheses of " capacity for caloric, latent heat,
