After a dinner at the Hotel Endieott, 

 Tuesday evening, November 14, an informal 

 reception was held for the members of the

 at the Brooklyn Institute of Arts and Sci- 

 ences, Mr. Geo. K. Cherrie had a paper on

 Birds.' He traced the life history of dif- 

 ferent species and exhibited specimens of 

 many of them. Mr. Wm. L. Finley spoke 

 of the water birds of southern Oregon, 

 illustrating what he said by many beautiful 

 lantern slides.
