verted into an acid. TJiis acid has a similar appearance to 

 the wax acid already described. It has however a much 

 higher melting-point, namely, 88°-89° C. The preparation 

 of the substance need not be again described.

I prepared the silver salt of this acid in precisely the same 

 manner as was prepared the silver salt of the cerotic acid.
