NOTES. 



The American Botanical Club is the name of a new society 

 for the study of plants by correspondence. The dues are but 25 

 cents a year, and all who are interested in plants are invited to 

 become members. Application for membership should be made 

 to J. C. Buchheister, Griffins Corners. Delaware County, N. Y. 



The Ninth Annual Report of the Chapter contains, in ad-

 a large amount of careful work, and the author is to be felicitated 

 upon its completion. 



BOOK NEWS.

 Manual in Elementary Biology"t that is intended primarily for

 a manual by any one studying alone. The book is about equally 

 divided between the biology of the plant and the biology of the 

 animal, and each part begins with the simple forms and ends with 

 the complex. The book is a departure from the old method of
