and such a view renders evident its constitution, but not its 
elevated melting point; the existence of the stearone of Bussy 
is therefore much to be doubted, for stearone should be formed 
from stearic acid by the subtraction of carbonic acid; but stearic 
acid, by the splitting of its atom into two new compounds, is 
resolved into margaric acid, and it is not very probable that 
both these decompositions could take place simultaneously. 
Lastly, the empyreumatic oil which accompanies ail the pro- 
ducts of the distillation of stearic acid, and which, after the cry- 
stallization of the margarone, remains behind in the ether, is ob- 
tained by evaporating the latter, contaminated with margarone, 
of which it dissolves much. By rectification and division of the 
product which passes over, it may be obtained in the first por- 
tions nearly free from margarone.
