John Wiley and Sons have recently piibhshed a German-English 

 Dictionary for Chemists, by Dr. Austin M. Patterson. It is a handy 

 book of 316 pages, containing not only strictly chemical words but 

 many that are used in plant physiology, agricultural chemistry and 

 mineralogy, as well as the common words which have acquired a tech- 

 nical meaning in these sciences. 



Mr. Samuel E. Cassino, of Salem, Mass., is collecting material for 

 a new edition of his well known Naturalist Directory, which he expects 

 to bring out late in the present year. This work comprises both ama- 

 teur and professional naturalists, and is useful to those who wish to 

 buy, sell, or exchange specimens of any sort.
