Mr. Putnam, in his remarks upon the fishes, confined 

 himself to the structure of the skeleton, pointing out 

 the homologies of the various bones with those of higher 

 animals, and the adaptation of the fish structure to the 

 special purposes for which it was designed. 



Mr. PUTNAM stated that since the Amesbuiy Field 

 Meeting he had received from Capt. J. A. Greely, of 

 Amesbury, a drawing of an Indian knife which differed 

 in details somewhat from any that he had mentioned in a 

 former communication to the Institute (see p. 111). 

 This knife was said by Capt. Greely to be made of "red 

 slate." It is nearly perfect, one end only being broken 

 off, as shown in the figure. Allowing for this missing

fragment the knife was about seven inches long; the 

 back is three-quarters of an inch deep and the blade 

 about one and one-half inches. The thickness of the 

 blade in the centre is about three-tenths of an inch. The 

 peculiar workmanship of the back, as shown in the sec- 

 tion, in the form of a series of uneven knobs, was prob- 

 ably intended to give firmness to the hold when grasped 

 by the hand. This specimen was found in a sand deposit 

 near Kingston Falls, Kingston, New Hampshire. The 

 figure, which is from the drawing of Capt. Greely, repre- 

 sents the knife of half its size.
