 The President in the Chair. 



The President, from the Committee appointed at the last 

 meeting, to inquire into the expediency of purchasing of 

 Mr. Rosvvell Field, a large slab of Quadrupedal Impressions, 

 reported: — That the slab was found near Connecticut 

 Puver, on the borders of Greenfield, a few- months since. 

 It is somewhat irregular in form, one side being about 6 ft.

 its form, size, thickness, and color, and of the form and 

 size of the impressions. The Committee are of the opinion 

 that this is the most remarkable specimen of quadrupedal 

 impressions which has been obtained in the United States, 

 and as the Society possesses the most remarkable specimen 

 of biped impressions which exists, they are of the opinion 

 that, by some means which the wisdom of the Society may 

 suggest, it may be obtained and added to their collection.

 H. Gillum, of Portland, Conn., had a collection of fossil 

 impressions of birds and quadrupeds, which he wished to 

 dispose of, as he was obliged to leave the United States. 

 Mr. Gillum was willing also to deposit them in the cabinet 

 of the Society until his return, provided the expenses of
