He also announced that the great ichthyological collections of 

 the late Mr. J. Carson Brevoort, — long a member of the Aca- 

 demy, — were now being studied and arranged at the American 

 Museum of Natural History. 



Vice-President Hubbard reported some interesting geolo- 

 gical observations, among them the discovery of a ''pot-hole." 

 four feet in diameter and eight feet in depth, at an elevation of 

 300 feet above the Hudson, opposite Catskill, N. Y. It was ex- 

 posed by the removal of some 50 feet of loose material (drift), 

 on the country-place of Mr. Frederick Church, the artist, at 

 that point. 



Near New Haven, Conn., the Winchester Arms Company have 

 bored for water into the Triassic sandstone. Although only two 

 miles from the metamorphic rocks which bound the sandstone 

 on the west of New Haven, the latter were not reached at a 

 depth of 2,400 feet; at this point the drill broke, still in the 

 sandstone, and the boring was abandoned. No water had been 

 obtained. A similar boring is now in progress at Northampton, 

 Mass. 



The President remarked on the extraordinary elevation of 

 the pot-hole described, as indicating a very powerful current at 

 so high a level above the present river, and acting for a very long 

 period. 



Prof. D. S. Martin related his visit to the new home of the 

 late Secretary of the Academy, Prof. Fairchild, at Rochester, 

 N. Y., and felt sure that the members would rejoice in hearing 

 of his exceedingly pleasant ''environment." He also reported 

 attending the entire session of the Association for the Advance- 

 ment of Science, at Toronto, where the Academy was repre- 

 sented by a number of its members, and the meeting as a whole 

 was extremely agreeable and interesting. 



Dr. N. L. Britton stated that after attending the Toronto 

 meeting, he had made a tour in the northern part of Canada, 

 and found there much interesting matter, both botanical and 

 geological, which he might lay before the Academy at a later 

 day. He also reported work done upon the Academy's librj^ry, 

 and upon the herbarium and flora of the State of New Jersey.
