implement recently discovered by Mr. W. C. Mills in the valley 
of the Tuscarawas, Ohio.” 
At a meeting of this Society, on March 7, 1883, Prof. George 
Frederic Wright of Oberlin, O., described and illustrated, b} 7 means 
of a large map, the line of the terminal moraine which marks the 
limits of glacial action in Ohio, extending from a point on the bor- 
der of Pennsylvania southwesterly to that of Kentucky, a little east 
of Cincinnati. After commenting upon the similarity of the ex- 
tensive gravel and terrace deposits of southern Ohio to those of the 
Delaware valley, near Trenton, N. J.,in which Dr. Charles C. Ab- 
bott first discovered the well-known palaeolithic implements made 
of the argillite of that region, Professor Wright predicted that 
similar discoveries of palaeolithic implements would be made in the 
gravel-beds of rivers in Ohio, flowing out of the glaciated region, 
if proper search were made for them. It will be recollected that 
this prediction met with a speedy fulfilment, and that Prof. Frederic 
W. Putnam exhibited at a meeting of this Society, on Nov. 4, 1885, 
such an implement which had been found by Dr. C. L. Metz at a 
depth of eight feet below the surface, in the gravel-beds of the Lit- 
tle Miami river, at Madisonville. This was made of black cheit 
and was of the same material, size and shape as one found by Dr. 
Abbott in the Trenton gravels. In the spring of 1887, Dr. Metz 
discovered another palaeolithic implement in the gravels of the Lit- 
tle Miami, near Loveland, at the depth of some thirty feet below 
the surface. 
I have now to exhibit a third implement of the same character, 
discovered by Mr. W. C. Mills, Oct. 27, 1889, in undisturbed strata 
fifteen feet below the surface, in a glacial terrace of the Tuscara- 
was river, at New Comerstown. The valley of the Tuscarawas is 
one to which particular attention had been directed by Professor 
Wright, as presenting specially favorable conditions for such dis- 
coveries ; and he has just given a detailed account of the physical 
character of the locality of the discovery in a letter to the New 
York Nation, April 24, 1890. 
Professor Wright has requested me to bring this new evidence of 
the existence of the palaeolithic man in North America to the con- 
sideration of this Society, and at the same time to express my opin- 
ion in regard to the genuineness and age of the object in question. 
I have accordingly brought here for comparison some half a dozen 
palaeolithic implements, from my own collection, all coming from
