Abstract 



The methyl, ethyl, propyl, w-butyl, w-amyl, octyl, and cetyl 

 esters have been prepared by the interaction of the silver salt and the 

 alkyl halide. In each series the melting-points do not rise con- 

 tinuously, but fall to a minimum in the butyl compounds; the re- 

 fractive indices rise continuously. The iso-a.my\ and benzyl esters 

 have also been prepared. Cetyl stéarate has been isolated from 

 permaceti by fractional crystallization from ether.
