EEPORT OF THE COMMITTEE OF THE AMERICAN ASSOCIA- 

 TION FOE THE ADVANCEMENT OF SCIENCE ON INDEX- 

 ING CHEMICAL LITERATURE. 



[Extract from the Proceedings, Vol. XXXIII, Philadelphia.rueeting, September, 1884.] 



The Committee ou I ndexiug Chemical Literature, appointed in 1882, 

 respectfully presents the following report of progress. 



We have the pleasure to announce that since our last report the fol- 

 lowing indexes have been published by their authors, the arrangement 

 of material being uniform with that of those previously issued : 



Ozone, second index, by Prof. Albert R. Leeds. 



Peroxide of Hydrogen, second index, by Prof. A. R. Leeds. 



Speed of Chemical Reactions, by Prof. R. B. Warder. 



Starch Sugar, by Dr. E. J. Hallock. 



Besides these a valuable contribution to chemical bibliography has 

 been independently published on a somewhat different plan, by Prof. 

 Albert B. Prescott and Mr. J. W. Baird. The full titles of the above 

 will be found at the close of this report. 



Two hundred and fifty copies of our report for 1883 have been sent to 

 chemists throughout the United States, the Smithsonian Institution 

 having kindly attended to the distribution by mail without expense to 

 the committee. This led to correspondence with several chemists who 

 reg-arded the scheme of co-oi^erative indexing favorably, and resulted 

 in several offers of assistance. 



Prof. William Ripley Nichols offers an Index to the Literature of Car- 

 bon Monoxide. 



Prof. L. P. Kinnicutt offers an Index to the Literature of Meteorites. 



Dr. Henry Leffmann reports progress on his Index to the Literature of 

 Arsenic. 



Prof. C. E. Monroe does likewise with reference to an Index to the 

 Literature of Explosives. 



Prof. A. B. Prescott and Mr. J. T. Craig offer an Index to the Liter- 

 ature of Phosphorus. 



Dr. H. Carrington Bolton has in preparation a second Index to the 

 Literature of Uranium. 



An offer was also received of an index to an element already on the 

 list of those published, but was withdrawn as soon as the author had his 

 attention called to the existing publication. This circumstance shows 

 forcibly the advantage of cooperation through this committee. 



We are pleased to announce that in consequence of our representations 

 the Smithsoniaij Institation Ijas consented to publish indexes to chemical
