certain biographical sketches contributed to the volume of 
American Medical Biographies edited by Drs. Kelly and 
Burrage. These related to ten American botanists: T. F. 
Allen, John Brickell of North Carolina, John Brickell of 
Georgia, A. W. Chapman, W. P. Gibbons, Thomas Hors- 
field, Albert Kellogg, P. D. Knieskern, H. P. Sartwell, and 
George Vasey. These were all written early in 1919, but 
the book was affected by the delays incident to such work 
at the present time, and did not make its appearance until 
September, 1920.

the year 1920

conditions in the book-binding trade we have been able 
to send but one shipment, and only 133 volumes have been

printed as usual in the Journal. There have recently 
arrived from England over 60 books, including several 
rare works. Among these is De Tussac’s Flora Antillarum 
in 4 folio volumes with elegant colored plates. 
Three new stacks were purchased and installed in the 
room at the east of the main reading room. Upon these 
were placed the books relating to geology, palaeobotany, 
microscopy, pharmacology and agriculture, in part, thus
