We have before us nine little books, designed to supplement Lectures 

 given to Teachers of the Public Schools of Boston, by the Boston Society of 

 Natural History. They are intended for the use of Teachers who desire to 

 practically instruct classes in Natural History. Beside simple illustrations and 

 instructions as to the modes of presentation and study, there are, in each 

 pamphlet, hints which will be found useful in preserving, preparing, col- 

 lecting, and purchasing specimens. The missing numbers are in course of 

 publication.
