Garden for six months of research, his special subject of investi- 

 gation being the toxic effect of dissociable salts on enzyme 

 activity. 



Mr. Norman Taylor, of the New York Botanical Garden, re- 

 turned on September 30 from a trip to the Sierra Maestra Moun- 

 tains, near Santiago, Cuba. Mr. Taylor accompanied Professor 

 B. E. Fernow, of Ithaca, N. Y., who went for the purpose of 

 making a timber survey of this area. During a four weeks' stay 

 in the mountains west of Santiago, collections were made for the 

 Garden Herbarium, together with some live orchids and cactuses 

 for the conservatory. Dr. Fernow gathered much valuable 

 information relative to the Cuban hard-woods, and also made 

 wood sections of the trees of economic importance. A map was 

 constructed of a part of this hitherto almost unknown, but ex- 

 tremely interesting country.
