Andrews, Emerson and others, than the longer 

 period usually ascribed to this work. A ' Note 

 on Certain Copper Minerals,' by A. W. Win- 

 chell, describes chalcopyrite and bornite found 

 as an accidental furnace product replacing the 

 iron rails in a calciner at a copper mine in Mon- 

 tana. The editorial comment includes an 

 obituary notice with a short biography of Edw. 

 W. Claypole, of Pasadena, California. 



The first number of a journal devoted to 

 biological chemistry, entitled Beitrdge zur 

 chemischen Physiologie und Pathologie — Zeit- 

 schrift fur die gesammte Biochemie, and edited by 

 Dr. Franz HofFmeister, professor of physiolog- 

 ical chemistry at Strassburg, was issued re- 

 cently. Its appearance may be interpreted as 

 the outcome of the increasing application of 

 chemical methods to the solution of biological 

 and pathological problems.
