became associate editor in 1853), the Annals of the N. Y. 
Lyceum of Natural History, the Memoirs and Proceedings of 
the American Academy, Hooker’s Journal of Botany, the Jour- 
nal of the Linnean Society, the Smithsonian Contributions to 
Knowledge, the North American Review, the Bulletin of the 
Torrey Botanical Club, the American Naturalist, and the BoTan- 
ICAL GAZETTE. 
Every one is familiar with the text-books, passing through 
many editions, which have made his name a household word, and 
which fully demonstrate that scientific truths can be popularized 
without being distorted or transformed into errors. Many learned 
societies of this country and Europe have honored themselves and 
im by electing him to membership and to offices of honor. For 
over fifty years he has been a member of the oldest natural his- 
tory society in Europe, Academia Ces. Leopoldino-Carolinee Na- 
ture Curiosorum, from which he received, on the fiftieth anniver- 
sary of his election, a letter of congratulation. 
In 1864, his offer to Harvard University of the immense and’ 
priceless herbarium which he had accumulated, on condition that 
a fire-proof building be erected to contain it, was accepted and 
the herbarium building put up. The special library attached to 
the herbarium, consisting of nearly 5,000 volumes, and over 
3,000 pamphlets, i is very lar gely due to his generosity. 
Since 1873, at which time he retired from the work of instruc-. 
tion, he has devoted himself rao oy to the preparation of the 
Synoptical Flora of North America, a work which will represent, 
when complete, the greater pie of the labor of a lifetime. No 
continue until he has finished this masterpiece of scholarly fever 
ing and critical acumen. 
Birthday Congratulations.
