II. On Chemical Nomenclature. 

 By Prof. W. A. Miller, M.D., LL.D., §-c* 



IT has been long felt by most chemists that some revision of 

 the nomenclature of their science has become necessary, 

 owing to the alteration which has taken place in the fundamen- 

 tal ideas now prevalent concerning the constitution of chemical 

 compounds, and which are no longer in harmony with much of 

 the system of nomenclature introduced by Lavoisier and his 

 colleagues eighty or ninety years ago. The present seems by
