them ample opportunity to publish their theses or researches. 
The Museum has not, however, limited its usefulness to being 
a simple educational University Museum; it has become, to a 
certain extent, a public institution, intended for a larger circle.* 
Finally, it has not neglected the interests of specialists, and 
has accumulated extensive collections, conveniently stored, and 
easily accessible to all who are able to make a proper use of this 
material. ‘These collections are in charge of a limited num- 
ber of assistants, whose time is not wholly occupied by their 
administrative duties. 
The publications of the Museum, in the shape of its eleven 
volumes of Bulletins and thirteen of Memoirs, give, with 
the addition of the Monographs thus far issued by workers at 
the Museum, a fair idea of the field covered by its various de- 
partments. It was but natural that during my administration

There is no reason why, with the increase of the Geological, 
Anatomical, Geographical, or other Department of the Museum, 
suitable accommodations and room for expansion should not be 
provided,

within a single square will in the future be the natural result of 
the present plans. It will facilitate greatly the work of the 
different departments, prevent needless duplications, and in- 
crease the efficiency and economy by a central management. 
The Library has grown from a few hundred volumes to an 
important collection of biological works, and it is constantly in- 
creased by its exchanges, purchases, and donations; it now 
numbers over 17,500 volumes, exclusive of pamphlets and of 
the Whitney Library. 
In 1860 the space covered by the first section of the building 
erected was eighty by sixty feet, and it contained in all sixteen
