In a former number of these Proceedings, an abstract is given 

 of a paper read before the Society, by Mr. Alger, on the Identity 

 of Beaumontile and Lincolnite with Heulandite. The identity of 

 the first with Heulandite is not now disputed ; but Prof Hitch- 

 cock having miyntained that the crystals in Mr. Alger's possession 

 were, possibly, not the mineral which he (Prof H.) had called 

 Lincolnite, but might be Heulandite, ]\Ir. Alger reaffirmed his 

 first opinion, and gave additional reasons for its correctness. 



Dr. S. Cabot, Jr., stated that he had recently received 

 a pair of canvass-back ducks, shot near Nevvburyport. He 

 had known only one previous instance of these birds being 

 taken in this vicinity, to wit, at Fresh Pond, by Capt. N. J. 

 Wyeth.
