THE HERBARIUM. 



The established practice of purchasing current collections 

 for the herbarium has been continued, and advantage has 

 been taken of a number of opportunities to secure useful 

 small herbaria at various times through the year. Among 

 the more important specimens that have been incorporated 

 are the remainder of the Rcverchon* herbarium (11,401 

 sheets), a representative series of duplicates from the Gan- 

 dogerf herbarium (7,591), a portion of the Fink % herbarium 

 (3,450), Dr. Hedgcock's herbarium (1,411), Lindheimer's^ 

 collections of 1849-1851 (1,317), Pitard's Canary Islands

The incorporated additions for 1907 amount to 35,876 

 sheets of specimens, of which 3,706, valued (unmounted) at 

 $185.30, were presented or, received by way of exchange;

 31,567 were acquired by purchase, the expenditure for such 

 specimens and material, shown by the Secretary's books, 



being $1,952.64. 



Among the unincorporated material forming a part of the 

 Engelmann herbarium § were some 20,000 specimens of 

 Texan plants collected by Ferdinand Lindheimer between
