148 REPORT ON INDEXING CHEMICAL LITERATURE. 



literature which shall be indorsed by this committee. The Smithsonian 

 places a limit to the number of pages which will be printed per annum, 

 but the limit is a generous one. 



By thus securing the assistance of the Smithsonian Institution, chem- 

 ists are assured of a reliable and authoritative channel of publication, 

 together with a wide circulation, and the plan of co-operative indexing 

 will undoubtedly receive a great stimulus. 



Finally, to extend more widely acquaintance with the existing indexes, 

 we append a complete list of those printed. A limited number of those 

 published by the New York Academy of Sciences can be had by ad- 

 dressing the chairman of the i)ublication committee of the academy, 

 Prof. D. S. Martin, 236 West Fourth street, New York City. 

 Eespectfully submitted.
