 are the heils at Pakenlmiu, examined hy the late Sheriff

 now found farther u]) in our estuaries than most others. 



Mr. Dickson informs me that a similar case occurs near 

 Clarenceville, ahout four miles from the Tnited States 

 frontier, and at an elevation of ahout ten feet ahove lake 

 Cham])lain. Si)ecimens from this place contain large 

 shells of Uiiio rectus and U ratfrlco/^iis, the latter with the 

 valves cohering, and a Li/iinira. Intimately nnxed with 

 these in sandy clay are valves of TcUina (rrdnkduflra and

I record these facts, without pledging myself to the 

 conclusion that these deposits really mark the margins or 

 river estuaries of the old l*leistf)cene of Canada, though 

 they will certainly hear that interpretation. In farther 

 connection with these facts, and in rehition also to the
