RECOGNITION OF PLEISTOCENE FAUNAS HAY

that the two teeth which he described had come from a stratum full 

 of bones. So far as the writer knows, there is nothing- opposed to 

 the idea that the deposit along- this river, as in the case of some 

 others, had been made at some time prior to the Wisconsin epoch. 

 Certainly, the deposit needs investigation. 



The other locality referred to is Columbus, Ohio. As long- ago 

 as 1848, Whittlesey reported the finding of bones and teeth of a 

 horse here, but they were lodged in fissures or clay-seams of the 

 limestone. They might have been deposited there at any time dur- 

 ing the Pleistocene. In 1875 Mr. J. H. Klippart reported that the 

 fossil jaw of a horse, with molars in good condition, had been

found while excavating for the exterior wall of the penitentiary. 

 Unfortunately we are not told what the depth was, nor the char- 

 acter of the deposits where the jaw was found. The penitentiary 

 is not far from the banks of the Scioto River, and the deposit with 

 the included jaw, if post-Wisconsin, may have been derived from 

 a pre-Wisconsin bed; but more probably, this deposit is of older 

 date than the Wisconsin stage. 



It is very interesting to study the distribution of the fossil horses, 

 with respect to the Wisconsin drift. They appear to have extended 

 northward to the south boundary of this drift all along the line 

 without having crossed it, except in the two cases mentioned. There 

 can hardly be a doubt that if this drift could be cleared away, horse 

 remains would be found beneath it far northward, and such remains
