General Meeting. April 6, 1881. 
The President, Mr. S. H. Scudder, in the chair. Twenty- 
three persons present. 
Prof. D. P. Penhallow gave an interesting account of the Ainos 
of Japan, relating their traditions of descent, and describing their 
settlements, occupations and rude arts. Specimens of weapons 
and implements were shown in illustration. 
Mr. Frederic Gardiner, Jr., gave a brief sketch of the work of 
the U. S. Fish Commission at a locality off the New Jersey coast, 
the results of which seemed to point at a possible new fishing- 
ground for deep-sea fishermen ; since the bottom fauna and tem- 
perature bore a strong resemblance to the conditions found on 
the Grand Banks. If these indications were not misleading the 
matter would prove of great practical importance. 
General Meeting. April 20, 1881. 
Vice-President, Mr. John Cummings, in the chair. Thirty-one 
persons present. 
Mr. J. S, Diller presented some farther facts with regard to the 
felsites and associated rocks in this vicinity, from which he drew 
the following conclusions : 
1. The stratified group contains the oldest rocks we know in 
this region, and before the extrusion of more recent eruptive 
rocks it probably had a much wider distribution on the surface 
than is now the case. 
2. The granites are not divided by metamorphosis from any 
part of the series of rocks (stratified grouj)) which they envelope, 
but are truly eruptive rocks, whose extrusion has occurred since 
the formation of the latter, and they are therefore the younger.
