 is that if he was in New Jersey at that time he was also upon the 

 banks of the Ohio, and the extensive terrace and gravel deposits 

 in the southern part of our state should be closely scanned by ar- 

 chaeologists. When observers become familiar with the rude form 

 of these palaeolithic implements they will doubtless find them in 

 abundance. But whether we find them or not in this state [Ohio],

 bounded on the east by the Little Miami River, where Dr. Metz has found palaeolithic 

 implements, is indicated by the figure, 9. 



if you admit, as I am compelled to do, the genuineness of those 

 found by Dr. Abbott, our investigations into the glacial phenomena 

 of Ohio must have an important archaeological significance, for 

 they bear upon the question of the chronology of the glacial period, 

 and so upon that of man's appearance in New Jersey."
