PROCEEDINGS OF THE CLUB 

 Meeting of April 12, 1927 

 This meeting was called to order at the American Museum of 

 Natural History at 8:25 p. m. The scientific program consisted 

 of an illustrated lecture by Dr. William Crocker entitled : The 

 Boyce Thompson Institute: its organization and equipment for 

 research . 



Dr. Crocker spoke of the handicaps, generally existing, to the 

 successful prosecution of research, and showed how the Boyce 

 Thompson Institute has tried to eliminate these as far as possible. 

 The equipment at the Institute, as well as some of the work now 

 in progress, were described and illustrated by stereopticon 

 slides. A more detailed account will be published later.
