Facts relating to tlie Ni pissing beacli are scattered through 
all these papers, but the principal number are contained in 
the second, fourth, and sixth. 
The Southwakd Extension of the ISTipissing Beach. 
On the JSforthern Shores. In the second of the preceding 
papers an account is given of the Nipissing beach at North 
Bay, and it is there shown that its relation to the ancient pass 
eastward to the Ottawa valley agrees perfectly with the sup- 
position that the great lakes had a postglacial outlet in that 
direction. The probable existence of this outlet had been pre- 
viously suggested by Gilbert,* and Spencer; and later obser- 
vations by Gilbert,! Wright, ;{: and the writer§ have substan- 
tially established the fact. Over the watershed east of North 
Bay this river had a width of a little over a mile, a maximum 
sidering this fact the orrorsare few: but the following corrections sliould 
be made: —
