 in Ohio was met not long after this. 



At a meeting of the Boston Society of Natural History f 

 for November 4, 1885, "Mr. Putnam showed an implement 

 chipped from a pebble of black flint, found by Dr. C. L.

 sonville, Ohio, in gravel eight feet from surface under clay, a, face view ; b, 'side 

 view. Note its resemblance to Fig. 126, from Trenton, New Jersey. (No. 40,970.)

Metz, in gravel, eight feet below the surface, in Madison - 

 ville, Ohio. This rude implement is about the same size and 

 shape of one made of the same material, found by Dr. Ab- 

 bott in the Trenton (N. J.) gravel, and is of special interest 

 as the first one known from the gravels of Ohio.'' Professor

 saying that he had since found another implement in the
