"It is invaluable to me in half a dozen sciences, and has often 

 paid me more than the subscription price." 



The Microscope, published by Dr. Chas. H. Stowell and wife, 

 Ann Arbor, has entered upon its third volume. It especially con- 

 siders the microscope in its relation to medicine and pharmacy. 

 The present is the best number we have seen of this excellent 

 magazine. Every physician ought to have a microscope, and then 

 subscribe for this journal, which is a marvel of cheapness. — Ex. 



The Lodran Meteorite. — The microscopic and general 

 characters of this meteorite which fell at Lodran, India, Oct. 1, 1868, 

 were quite fully described by Tschermak in 1870 (Sitzungsb. Akad. 

 Wissensch. Wien, 1870, lxi). Dr. Stan. Meunier finds, on studying 

 a section, that it appears to be composed of bronzite, olivine, 

 pyrrhotite, chromite, and grains of metallic iron. If, however, a 

 chip is heated and then suddenly plunged into mercury, the sili- 

 cates fall to pieces, while the metallic portion is seen to form a very 

 fine network or sponge-like mass. This network is the same as, 

 but finer than, that formed by the iron in the celebrated Pallas 

 meteorite, to which this is allied. Dr. Meunier regards the Lodran 

 meteorite as a true sandstone, having a metallic cement. The 

 metallic portion was evidently posterior to the accumulation of the 

 silicate grains, which must, before their cementation, have formed 

 a true meteoric sand. He does not regard water action necessary 

 to produce such a sand, but thinks, rather, that it was produced by 

 volcanic action. — Comptes Rendus, xcv.
