We are please to note the enrollment of two such distinguished 

 Concliological veterans as Dr. Newcomb and Wm. G. Binney. ]\Ir.

 of much use to them." Dr. Newcomb writes in the same kind spirit, 

 desiring to aid younger students in tlieir work. 



Dr. Newcomb is now 82 years of age — probably the oldest living

 collected uj)on 23 of the West India Islands, in the interior of

 many papers by him having appeared in the Conchological 

 journals of Europe and America. As he himself writes " I am al- 

 most alone ; my old friends Agassiz, Gould, the elder Binney, 

 Anthony, Lea, Reeve, Cuming, Swift, Bland, Wheatley and many
