collection were already possessed by the Academy. On this account, 

 therefore, and as the number of cultivated specimens was large, the Com- 

 mittee deemed it unadvisable to incorporate it with the Herbarium of the 

 Academy, but concluded upon keeping it entirely distinct, adopting, how- 

 ever, a similar plan of arrangement as in the Herbarium of the Academy, 

 viz., combining, as far as possible, the Linnean or Artificial with the Na- 

 tural System. 



To accomplish this duty occupied the time and attention of the Commit- 

 tee for several months. The best and most characteristic specimens were 

 selected, transferred to paper of uniform size and color, with the generic 

 name attached to the left hand upper corner of the sheet; the genera being 

 arranged in their appropriate natural orders, commencing with those latter 

 which contained the largest proportion of genera belonging to the first 

 Linnean class, and' so on proceeding to the last this being the plan of the 

 Herbarium of the Academy alluded to above. 



As thus completed, the collection comprises 1298 genera, including up- 

 wards of 7000 species. Of these, 5623 species are Phoenogamous, includ- 

 ed in about 130 natural orders; and 1272 species are Cryptogamous. Of 

 the latter, the Ferns embrace 132 species; Equisetum, LycopodiumJ and 

 the Marsileaceae, 29 species; Hepaticae 65 species; Musci 309 species; 

 Algaj 122 species; Lichenes 152 species; and Fungi 445 species. To these 

 are to be added 18 species of Corallia, and a number of plants to which 

 neither the generic nor specific name was attached. 



The whole has been distributed into thirty-6even folio volumes of large 

 size, occupying an entire case six and a half feet high, four feet wide, and 

 tweuty-one inches in depth. 



The duplicates are very numerous, and will answer for exchanges. 



The new catalogue, alluded to above, has been. found necessary, on ac- 

 count of there now being two separate collections, the previous catalogue 

 referring but to one. It is furnished with a double column of reference, so 

 that a genus contained in both collections can be very readily found. 



A number of donations, some of which are of much value, have been 

 received by the Academy during the year. These have been already 

 noticed in the published Proceedings at the time of presentation. 



The chief donors have been our fellow members A. Browne, Esq., 

 and Mr. R. C. Taylor; Dr. George Engelmann, of St. Louis, Missouri, 

 and Prof. Short, of Louisville, Kentucky. 



The duty of incorporating these donations with the Herbarium has been 

 necessarily deferred until next year. 



On behalf of the Committee,
