THE BOTANISTS OF PHILADELPHIA. 371 



On October 10, 1897 was organized the Botanical 

 Society of Pennsylvania, largely through the interest and 

 energy of Professor Macfarlane. This Association has 

 already done much active botanical work. 



His published writings, in recent years, have mainly 

 been on sensitive plants, and on the best methods of 

 organizing botanical museums and gardens. 



He is a member of the Royal Societ}^ of Edinburgh, 

 Academy of Natural Sciences of Philadelphia, American 

 Philosophical Society, and others.
