or Calorific Power of various Liquids. 217 
Consequently the capacity of water for heat is greater than 
that of oil of linseed in the proportion of 82,55 to 36,464: and 
if we express the capacity of the-water by wily as is usually done, 
the capacity of the above oil ought to be expressed by the frac- 
tion 0:44172. 
These details must no doubt appear superfluous to those who 
are versed in the higher branches of knowledge, and who are 
accustomed to express the most complete relations by algebraical 
signs: but it must be recollected, that the subject of which | 
treat is familiar to few, and that it is necessary to explain with 
rigorous accuracy the principles upon which the method em- 
ployed is founded, as well as the manner of using the apparatus 
which I recommend.
