36 Report of the President 



The American Museum of Natural History, in conjunction 



with certain other museums, is reciprocating with the Buffalo 



Society of Natural Sciences in the exchange of 



Exchange membership privileges. When a Member of the 



of Mem- American Museum visits the Museum of the Buf- 



bership 



Privileges falo Society and presents his membership card at 

 the office, the privileges accorded its Members will 

 be accorded the Member of the American Museum. This 

 plan, with which we are heartily in accord, was suggested by 

 the Buffalo Society of Natural Sciences, with the hope that 

 such a step would promote the friendly relations already exist- 

 ing between these museums, encourage and stimulate the in- 

 terest of Members, and serve to increase scientific knowledge.
