 But I can the less persuade myself that this liquid can 

 furnish in its combustion so much heat, because one pound 

 of white wax furnished no more than what was sutEcient 

 to heat 94-632 pounds of water to the same degree. 



According to the analysis of M. de Saussiire, 100 parts

 Supposing that the 19 parts of oxygen are combined with 

 3-6 parts hydrogen, so as to form with them 21*6 parts 

 water, 100 parts of this kind of ether ought to be composed
