170 Scientific Intelligence. 



III. Miscellaneous Scientific Intelligence. 



1. OstwalcPs Klassiker der Exakten Wissenschaften. — The latest 

 additioDS to this valuable series of scientific classics are Nos. 97 

 to 103, whose titles are given below. We have often had occa- 

 sion to call attention to this series before, and its value must now 

 be well appreciated by all of those interested in physics and 

 physical work. It would be difficult to overestimate the impor- 

 tance to the physical student of having before him such papers 

 as are here brought together: They are all of the highest charac- 

 ter, and a large part of them, as originally published, are com- 

 paratively inaccessible ; but they are here republished in con- 

 venient form, ready for the student in his study, or the worker 

 in the laboratory. Space forbids any separate notice of the indi- 

 vidual memoirs here mentioned, and indeed this is unnecessary, 

 since they are too well known to require it. Ostwald's Series 

 gains additional interest from the fact that an undertaking on 

 somewhat similar lines is being carried forward in this country 

 (already noticed in this Journal), as Harper's Scientific Memoirs, 

 edited by Professor Ames of Baltimore.

2. University of Tennessee Record of Scientific Engineering. 

 Published by the University of Tennessee Press, Knoxville, 

 Tennessee. — Number V of this publication, for November, 1898, 

 pp. 343-405, has been recently received. It contains a number 

 of original scientific papers, and gives evidence of the scientific 

 activity at the University of Tennessee. Among the papers we 

 notice one on Nutrition Investigations, by Charles E. Wait ; 

 several papers on Chemical Analytical Methods; another on 

 Meteorological Observations by means of Kites, by W. M. 

 Fulton ; also, Notes on the Flora of West Tennessee, by S. M. 

 Bain.
