It is evident that this paper is merely an introduction to the possi- 

 bilities in the direction indicated. Not oidy have other compound 

 the same acids been already discovered, but many other acids, notably 

 bydriodic, lactic, sulphocyanic, etc., show that they are capable of 

 forming similar compounds. Moreover, the substituted ammonias may 



apparently take the place of the simple substance in mosl of the 1 1- 



pounds. A few of these preparations are to be seen in the University 

 exhibit at the World's Columbian Exhibition. The study of all these 

 interesting substances will be continued in the immediate future al t liir- 

 Laboratory.
