by members, and objects in considerable variety were 

 described and examined. 



Many of the papers above mentioned were followed by 

 questions and discussion on the part of members present, 

 which added much to the interest of these occasions. 



The attendance has for the most part been about equal 

 to tli at of last year. 



Respectfully submitted,

CORRIGENDA. 



In my paper on "An Interesting Geological Locality at Cornwall, N. 

 Y.," in the Transactions of Vassar Brothers Institute for 1883-4, there 

 stated to be only the preliminary observations of a single brief visit, 

 the "Van Duzer" mine is assumed to be identical with the "Town- 

 send" mine, mentioned formerly by Horton and Mather. This was 

 the impression made on my mind by the scanty information gained 

 on the ground. But I have received, since, more reliable informa- 

 tion from Mr. Nelson H. Darton, who is making a thorough strati- 

 graphic exploration of that region. It appears that the Townsend mine 

 is distinct from the Van Duzer, though similar in its features, and that 

 it lies a little farther to the south. Statements quoted in the paper of 

 Horton and Mather, with reference to the Townsend mine, had a mis- 

 application, therefore, in some minor respects, as referred to the Van 

 Duzer mine. 



Also, in the list of waterlime fossils, in place of " Atrypa plicata," 

 read " Spirifer vanuxemi."
