The Revue Generate de Botanique, now in its thirtieth volume, publishes 
articles and memoirs on the various phases of botany — pure and applied — 
by French and foreign authors. The articles are illustrated by numerous 
text figures and plates, both in black and in color, including portraits and 
charts. In addition to original articles and memoirs, the i^mte contains 
notes of the principal works of French and foreign botanists. 
The Revue Generale de Botanique has appeared monthly ever since its 
foundation. It has appeared regularly throughout the entire duration of 
the war, without interruption, and notwithstanding the actual increase of 
the cost of printing and of paper, the subscription price has not been 
changed. Each volume comprises about 450 pages with about 20 plates, in 
addition to numerous text figures. 
The foreign subscription price is 22 francs 50 per volume. Single 
numbers are not sold separately. Specimen copies furnished on request.
