11, 5 Electro-Aimants et L’ Adherence Magnetique par M. J. Ne sein 
Paris, 1860. 8vo.—This book is devoted chi efly to a recital of the Au- 
thor’s experiments 0 on various forms of Electro-magnets m made durin 
investigation to test the adaptation of magnetic adhesion for arresting the 
motion of railway trains. Most of the experimental data have already 
appeared in this Journal and the Author’s proposed ieee was 
given in vol. xxx, p. 413.

author’s work on Organic Analysis,* and will be well received as a ‘os 
and careful exposition of the views of the new school in chemist

latent and specific heats, densities, pene volumes, rm FR ion of heat in 
combustion, optical constants, and laws of absorption and cohesion. The 
chapter on the classification of organic hades by series is yen origi-
