ture of the hand. The melting point was found to be 25°. P. 

 oxy m. methylacetophenonemethylester. 6.47 g. of ketone 

 gave 3.82 g. of the ester. 



P. oxym. methylacetophenonethylester. This was pre- 

 pared in a manner similar to that of the methyl ester. 

 The product however appeared as a white solid after dis- 

 tillation. It was purified as before, and dried on a porous 

 plate. The yield was better, being 77.6 per cent of the 

 theory. This compound is redistilled at 220°-2B0'^ under 

 74 mm. pressure. M. p. 34.5*-'. 



The manufacture of the cetyl ester was attempted in the 

 same manner that the methyl and ethyl esters had been 

 made, but no product could be obtained which would solid- 

 ify, and it had to be abandoned. 



The experimental work ended here owing to lack of 

 time.
