privileges of the laboratories, library, and herbarium, during 
the year, and that investigations covering a wide range of 
subjects have been prosecuted by them. Visiting investiga- 
tors from other institutions have also been given facilities in 
the laboratories. 
In this department, as in others, the additional furniture 
completed during the spring has rendered work and study 
much more convenient and effective. 
Lectures. 
As in previous years courses of public lectures have been 
delivered on Saturday afternoons in the spring and fall in 
the lecture-hall of the museum building. These have been 
duly announced by card to the members of the Garden and 
by publication of their titles in the JouRNAL and other periodi- 
cals. The notices to members have included, as before, in- 
vitations to inspect various departments of the Garden in 
advance of the lectures on Saturday afternoon under the 
guidance of members of the staff, and these invitations have 
been taken advantage of by many members. 
Exploration. 
The work of obtaining plants and specimens for the col- 
lections from various parts of the world has been continued 
during the year as funds for this purpose became available, 
several members of the staff participating in this work. The 
most valuable of all scientific material brought into the col- 
lections is obtained only in this way, and much of the success 
in establishing the collections has been due to our ability to 
conduct explorations. During the year this work has been 
accomplished by means of appropriations from our general 
fund, and by the following contributions of money credited 
to our special exploration fund:
