268 BOGERT— CARBON COMPOUNDS. [April 20. 



discussed together, examples for laboratory practice may be drawn 

 from either the acyclic or the cyclic field. 



The author claims no originality for this suggested classification, 

 except so far as certain details are concerned, for it was recom- 

 mended and adopted so long ago as 1864 by that distinguished Rus- 

 sian chemist, Butlerow, in his " Lehrbuch der organischen Chemie," 

 and has won adherents in this country in Professors W. A. Noyes, 

 Kremers, and possibly others. My reasons for presenting it at the 

 present time are the evident need for some change in our present 

 system, brought into the foreground by the approaching publication 

 of the new edition of Beilstein's monumental " Handbuch der 

 organischen Chemie" and the creation of national commissions on 

 the nomenclature of organic compounds, and my firm belief, as the 

 result of experience, that the adoption of such a system will aid in 

 inspiring and stimulating greater interest in the study of organic 

 chemistry.
