428 PROCEEDINGS OF THE ACADEMY OF [1885. 



Burk. A large part of the new accessions have been mounted, 

 and the same work lias been prosecuted in the North American 

 Herbarium, of which now about one-half has received this care, 

 so necessary to the permanenl preservation of the specimens. 



The donations received during the year amount to 1687 species 

 of phanerogams and ferns, and 383 species of lichens and fungi, 

 in all 2070 species. Of the former, 395 species are new to our 

 Herbarium, while probably a large part of the fungi and lichens 

 arc also new to us. The total number of species presented is less 

 than in sonic former years, but it will be seen that the proportion 

 »f rim- accessions is not materially diminished. Of the 2070 

 species received 1360 are North American, 37 South American, 

 and 667 are from the old world. 



Among the donations we may specify the valuable contribution 

 of exotic plant- received from Dr. Asa Gray of the Cambridge 

 Herbarium; a series of 365 species collected by Mr. Meehan in 

 Western North America in 1883; and a valuable collection of 388 

 species of S. African, Australian and European plants from Mr. 

 Win. M. Canby. 



A complete list of the donations accompanies this report, and 

 will appear in its proper place in the list of Additions to the 

 Museum.

REPORT OF THE MINERALOGICAL AND GEO- 

 LOGICAL SECTION. 



The Director of the Mineralogical and Geological Section of 

 the Academy of Natural Science would respectfully report that 

 meetings of the Section have been regularly held, but that owing 

 to the absence of active members, and other causes, the attend- 

 ance has not been as large as in former years. Considerable 

 accessions to the cabin el have been made — a number of desirable 

 specimens having been purchased with the funds of the Section. 



Respectfully submitted, 



Theo. D. Rand, 



Director.
