AT 
issued for January of this year, contains an interesting account of 
a visit of exploration to Cuba made by Dr. C. Stuart Gager, the 
director, last autumn. It also contains the articles of agreement 
between the City of New York and the Brooklyn Institute of 
Arts and Sciences concerning the Brooklyn Botanic Garden. 
A comprehensive project for research on the Cactaceae has 
been organized by the department of botanical research of the 
Carnegie Institution of Washington. Dr. J. N. Rose, of the 
idhabied by these plants in Mexico and the United States and 
published extensively on the family, has been appointed research 
associate. e has been granted a furlough from the museum, 
which also furnishes working quarters and facilities for handling 
the living collections. Dr. N. L. Britton, who began organizing 
a collection of cacti in the New York Botanical Garden in 1900, 
and has since made extensive studies of the group, has also been 
appointed research associate, without salary. By the action of 
the scientific directors of the garden he will be given some respite 
from other duties to enable him to participate in this work. 
The garden also contributes its extensive collections, and some 
of its explorational effort to the project. Dr. D.S. Johnson, of 
Johns Hopkins University, will spend several months in 1912 
on the morphology and physiology of the fruits of the group, and 
Professor J. G. Brown, of the University of Arizona, will con- 
tinue his studies on the general morphology of Opuntia and 
Carnegiea begun while acting as assistant at the Desert Labora- 
tory. Other contributions will be made by the members of the 
staff and codperators of the Desert Laboratory.—From Science. 
On the evening of February 13, Dr. Forrest Shreve, of the 
staff of the Desert Laboratory of the Carnegie Institution of 
Washington, delivered before the Torrey Botanical Club a very 
interesting and instructive illustrated lecture on “Some Botan- 
ical Features of a Desert Mountain Range.” 
In continuation of exchanges of herbarium and museum speci- 
mens, the Garden last December sent to the Muséum National 
d’Histoire Naturelle at Paris a consignment of 185 specimens of
