NOTES AND LITERATURE.

Near the end of the book is a synoptical table or key to the prin- 

 cipal woods distinguished by features visible to the naked eye or 

 under a magnification of about 20 diameters. 



A preliminary part of about 40 pages states clearly and concisely 

 important conclusions drawn from French forestry statistics, modern 

 views of the influence of forests on water supply and climate, and 



nomic considerations, etc., on forest production. The volume closes 

 with a full index, thus making this part of the treatise complete in 



Kraemer's Course in Botany and Pharmacognosy 1 presents in 



anatomy of vegetable drugs and their microchemistry. Following the 

 general morphological part are chapters devoted to the description 

 and discrimination of drugs in the crude state and in powder. In 

 this part excellent keys are included by means of which the student 

 is helped to recognize any official drug. A third part deals briefly 

 with the most useful reagents required in pharmacognosy, and with 

 simple methods of making microscopic preparations. There are 17 

 plates containing 128 figures, 6 of which are colored. All are clearly 

 drawn and well printed on clayed paper. Besides a full general 

 index there is a special index to powdered drugs. 



The book is remarkably well calculated to give students of phar- 

 macy all the botany they need in preparing for their profession. The 

 style is unusually clear and direct, and an orderly comprehension of 

 the more difficult topics is much facilitated by the use of tables. In 

 preparing this work Professor Kraemer has done a good service to 

 many students and teachers. 



Notes. — The Journal of the New York Botanical Garden, for 

 February, contains information concerning the research scholarship 

 recently established at that Institution; an interesting account by 

 Mrs. Vail of Jonas Bronck and his Bouwery in New Amsterdam, and 

 some chemical studies of Sarracenia purpurea, by Gies. 



" Why Popcorn pops " is the subject of an article by Wilbert in the 

 American Journal of Pharmacy for February.
