JU THE BOTANISTS OF PHILADELPHIA. 



N' early all of the specimens have been cleaned, sorted, put 

 into neat pockets, labeled and fastened into the books by 

 her own hands. Mr. Ellis himself says, that owing to his 

 great correspondence ;md the enormously burdendsome 

 quantity of material constantly being sent to him for 

 determination and comparison, he would not have been able 

 to get out the " N. A. F." without her valuable aid. 



From 1876 to 1879, not having at that time the books and 

 exsiccati collections necessary for independent work, many 

 specimens were sent to Dr. M. C. Cooke, who determined 

 and published them in Greuillea. Under the circumstances 

 then existing this course seemed necessary, though it called 

 out some adverse criticism at the time. 



Since 1880 Mr. Ellis has been associated with Mr. Ben- 

 jamin M. Everhart, who has freely placed at his friend's 

 disposal his splendid botanical library and extensive 

 mycological collections, and to his aid and counsel Mr. Ellis 

 lee Is greatly indebted. 



In July, 1878, Mr. Ellis was elected a corresponding 

 member of the Academy of Natural Sciences of Philadel- 

 phia. In August, 18.v2, he was elected a corresponding 

 member of the Cryptogamic Society of Scotland, and in 

 December of the same year was elected corresponding mem- 

 ber of " Die Kaiserlich-Konigliche Zoologisch-Botanische

 considerably in his younger days, he was always fond of 

 home, as can be plainly seen from his invariable return to 

 Potsdam, his native town, after every venture into the outer 

 world. Too much excitement of anv kind affects him
