J 3^ Action of Chlorine on Cinnamic and Benzoic Acids. 



^ Ck, v. Acid obtained by means of chlorine gas sent through 

 a^Jiot solution of benzoic acid for about 56 hours. 



a. 0-3334 substance, 0*6675 carbonic acid, and 0*097 HO. 

 ^',b, 0*2068 substance, 0*4165 COg, and 0*0665 HO. 



c. 0*3522 substance gave with hydrate of lime 0*3125 chip,-,

It will be observed by reference to the formulae given in a 

 previous part of the paper, that the acid A. obtained by hypo- 

 chlorite of lime corresponds to the acid with two equivalents 

 of chlorine. No. II. , which was treated with still more hypo- 

 chlorite of lime, gave a mixture containing acids with two and 

 three equivalents of chlorine; and No. III., in which the 

 treatment was carried still further, corresponds to an acid 

 with nearly three equivalents of chlorine.
