12 ART. 4. — Y. SHI BATA : THE ACTION OF 



On fusion witli potash at 160° the smell of benzophenone 

 ■was distinctly perceived, but on dissolving in water, tJie fused 

 mass gave nothing but a small (juantity of tlie original substance. 



Analysis of the substance gave the following results : 



1) 0.'2240 g. of the substance gave 0.7390 g. of COo and 

 0.1081 g. of HoO. 



2) 0.2030 g. of the substance gave 0.6674 g. of CO, and 

 0.0972 g. of HoO, or

III. The action of benzyl magnesium chloride on o-phthalic 

 acid diethyl ester. 



The proportion of the substances taken and the method of 

 procedure were just the same as before. But it was found that 

 the reaction was much more violent than in the previous cases,
