EXPERIMENTS OF BREWSTER. 91 

 t 



amount of caloric around their particles is, that 

 it is higher in water than in ice, higher in fluid 

 than in solid sulphur, as it is in all those bodies 

 which are composed chiefly of carbon and hy- 

 drogen, such as alcohol, aether, the volatile and 

 fixed oils, than in water, the specific gravity of 

 which is greater, as will be seen from the fol- 

 lowing table, taken chiefly from the experiments 

 of Sir David Brewster. It will also be seen, 

 that it is higher in the diamond, which consists 

 of pure carbon (condensed by an immense pres- 

 sure,) than in any other solid body, if we except 

 phosphorus and sulphur, both of which are 

 highly inflammable, and afford very large quan- 

 tities of caloric by combustion.
