Dr. Kane on the Combinations derived from Pyroacetic Spirit. 125 



In order to ascertain whether there was formed, by the action of small quan- 

 tities of a base on this chloral, a body analogous to chloroform, I added to a cer- 

 tain quantity as much potash liquor as dissolved about one-half. The residual 

 heavy fluid, which differed but very little in odour and appearance from its 

 state before the action of the potash, was analyzed. 



A. 0.500 material gave 



0.164 water. 

 0.547 carbonic acid. 



B. 0.774 material gave 



Whence follows 



0.841 carbonic acid. 

 0.241 water. 



A. B. 



Carbon = 30.25 30.04 



Hydrogen = 3.64 3.44 



As the quantity of carbon, remaining almost absolutely unaltered, proved the 

 fluid analyzed to be unchanged chloral, it was thought unnecessary to determine 

 the chlorine by itself. 



The results just obtained may be considered as agreeing tolerably well with 

 each of the following formulae :
