addition of glycerin, it is advisable to place the preparation in a moist 

 chamber with a drop of the staining solution at the edge. The water 

 slowly passes off and the glycerin gradually takes the place of it. Strong 

 glycerin is used as a preservative. 



— The Editor of the Index Medicus calls our attention to a misunder- 

 standing which led us to criticise the plan of his publication in our last 

 issue (p. 225). We readily modify our remarks by quoting from his 

 letter as follows : " In the actual work of indexing, no distinction what- 

 ever is made to indicate doctrine ; articles from all sources being entered 

 under their subject-heading merely." 



— We notice a new scientific periodical, the tirst number of which has 

 reached us, entitled Lo Bollettino Scientifico, edited by Doctors De Giovanni 

 Achille, Maggie Leopoldo and Zoja Giovanni, professors in the University 

 of Pavia. It is published in Milan. 



— The National Committee on Micrometry is composed as follows : 

 F. A. P. Barnard, LL. D., President of Columbia College, New York 

 City, Chairman ; R. H. Ward, M. D., Troy, N. Y., Secretary ; George E. 

 Fell, C. E., Buffalo, New York ; Henry Jameson, M. D., Indianapolis, 

 Indiana; Prof. S. A. Lattimore, Rochester, N. Y. ; Prof. Edward W. 

 Morley, Hudson, Ohio ; Joseph G. Richardson, M. D., Philadelphia, Pa. ; 

 Prof. Stephen P. Sharpies, Boston, Mass. ; Prof. H. L. Smith, Geneva, 

 N. Y. ; Prof. Albert H. Tuttle, Columbus, Ohio; J. J. Woodward, M. D., 

 Washington, D. C. ; Lester Curtis, M. D., Chicago, 111. 



Nearly all the prominent microscopical societies of the country are 

 represented on the above Committee. 



— 77^1? A))iericaH C/ieiiiica/ Journal, edited b\- Professor Ira Remsen, 

 with the aid of chemists at home and abroad, is a new periodical, the first 

 number of which appeared last April. Six numbers will form a volume of 

 400 to 500 pages. It will contain : " Original papers, articles from other 

 journals, reviews and reports" and "notes." We hope it will prove a 

 success, for it is under able management, and, judging from the first 

 number and the Editor's announcement, it is destined to be valuable both 

 to professional and practical chemists. Not a single thoroughly scientific 

 journal devoted to chemistry in a country of nearly fifty millions of inha- 

 bitants ! How great must the thirst for knowledge be. 



— Mr. H. T. Butlin has been studying the "fur" on the tongue, and 

 finds it to consist of the gloea of certain fungi. By cultivation, he found 

 Micrococcus and Bacillus siibtilis always present. Besides these he 

 sometimes found Bacterium feriiio, Sarcina ventriculi, Spiroclueta 

 plicatilis and Spirilluvi. 



— In the Coinptcs Rendus, C. Chamberland mentions a minute organism 

 which is found in almost every organic solution that has been made 

 neutral in reaction by potash. The germs or spores of this organism are 

 said to retain their vitality after boiling for several hours ; but a tempera- 

 ture of 115° C. soon kills them.
