486 PROCEEDINGS OP 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 will 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. '
