Ang:nst, 1882, that they had considered tliree methods of collectiiiji:^ "fil- 

 ter ial for the indexes, viz : 



1. Reviewing the Catalogue of Scientific Papers published by the 

 Koyal Society (8 vols., 4to). 



2. Indexing sjiecial journals by dilferent individuals and collating 

 t lie matter. , 



3. The independent plan, -whereby each chemist indexes all the jour- 

 nals available to him with releren<;e to a given element in which he is 

 presumably especially interested. 



Each of these schemes is open to objections, which need not be named. 

 Oa the whole, the third plan seeme<l to a majority of the committee the 

 only feasible one for the present. 



The report considers also the best arrangement of material, and three 

 ways are suggested : (1) Curonologically ; (2) alphabetically by authors ; 

 (3) topically. 



The committee do not venture to dictate to volunteers an<l independ- 

 ent, workers, but recoL'imend the chronological arrangement, accom- 

 ])anied by a topical index. 



In September, 1884, the committee reported that several indexes had 

 b<'Cii published during tlie twelve months intervening, and that more 

 were in progress. They also announced that the Smithsonian Institu- 

 tion has consented to publish the indexes to chemical literature in- 

 dorsed by the committee, limiting somewhat the number of pages per 

 annum. The Smithsonian Institution also distributes free of expense 

 the circulars of the comnn'ttee. 



The indexes already published include the following : Uranium, by 

 n. Carrington Bolton, 15 pp.; Manganese (1596-1874), by H. Carrington 

 Bolton, 44 pp.; Ti't a nium, hy Edward J. Hal lock, 22 pp.; Vanadium, 

 by G. Jewett Bockwell, 13 pp.; Ozone, hy Albert E. Leeds, 32 pp.; 

 Peroxide of Hydrogen (1818-'78), by Albert R. Leeds, 11 pp. ; Elec- 

 trolysis, by W. Walter Webb, 40 pp. ; Speed of Chemical Reactions, by 

 Robert B. Warder, 3 pp. ; Starch- Stigar, by Edward .1. Hallock, 44 pp.; 

 Ozone (1879-83), by Albert R. Leeds. IG pp.; Peroxide of Hydrogen 

 (1879-'83), by Albert R. Leeds, 3 pp.; Dictionary of the Action of Heat 

 upon Certain Metallic Salts, by J. W. Baird and A. B. Prescott, 70 ])i>. 

 8vo. New York. 



The first two were published in the Annals of the New York Lyceum 

 of Natural History and all the rest in the x\nnals of the New York Acad- 

 emy of Sciences, except that on Starch-Sugar, which was published by 

 the LTnited States Internal Revenue Department, Washington, D. C; 

 and that on Speed of Chemical Reactions, which appeared in the Proceed- 

 ings of the American Association for the Advancement of Science. , 



A limited number of those published by the New York Academy of 

 Sciences can be had of Prof. D. S. Martin, 23G West Fourth street, New 

 York City, the chairman of the publication committee.
