 no more passed over and the temperature dropped. 

 The residue (about 2cc) solidiifed on cooling. 

 This was dissolved with ether and placed in a 

 crystallizing dish. It failed to crystallize, 

 remaining as a yellow wax with slight odor. 



The first fraction, constituting the 

 greater part of the oil, was distilled again 

 and constants determined as follows;

There was no action on the oil "by fresh-
