PROCEEDINGS OF THE ACADEMY OF 
[1890. 
Besides these American plants, we may specify a valuable collec¬ 
tion of 700 species recently made by Prof. J. Bornmiiller, in the 
province of Amasia, in the northern portion of Asia Minor. For 
this contribution, of which more than half the species are new to 
our shelves, we are indebted to the kindness of Mr. W. G. Warden, 
of Germantown. 
Other lesser contributions w r ill appear in the usual detailed list of 
plants recorded in the additions to the museum. 
The total number of species received during the year has been 
3,289, of which 2,811 were Phanerogams and vascular Cryptogams. 
Of these latter 1,161 are believed to be new to our collection, and 
among them are representatives of 49 new genera; 241 are from 
our own territory; 1,759 are from tropical America; 777 are from 
the northern portions of the eastern hemisphere, and 34 are from its 
more southern portions. The remaining 478 species received are of 
the lower Cryptogams, and include some valuable collections of 
mosses. The additions of the past year raise the estimated number 
of species of Phanerogams and vascular Cryptogams in the 
Academy’s Herbarium to 30,053. 
The Vice-Director of the Section has contributed a large share of 
his valuable time to the study and determination of the plants re¬ 
ceived from Prof. Rovirosa, and from the Heilprin expedition. In 
this work he has been aided to some extent by Mr. Burk and by 
the Conservator, who have therefore not been able to accomplish as 
much as heretofore in the work of mounting the collection, yet 
all the North American accessions have received this attention, and 
all others have been placed in covers and carefully distributed.

REPORT OF THE MINERALOGICAL AND GEOLOGI¬ 
CAL SECTION. 
Fewer meetings than usual have been held this year, most of 
them under the new arrangement with the meetings of the Academy, 
on the first Tuesday of each alternate month. Long-continued 
absence of the more active members, has also operated this year, 
as it did last, to the detriment of the meetings, but they have not 
been without interest.
