E. Desor: Les Cascades du Niagara, et leur Marche rétrograde, avec 
une carte et une coupe géologique (Extr. des Bulletin Soc. Sci. Nat. Neu- 
chatel, tome iii.)--M. Desor, in his interesting memoir, concludes that 
the Falls of Niagara recede at a rate nearer 3 feet per century than 3 
feet a year. He also argues that, in consequence of the position of 
the shale below, the height of the falls will increase, as they recede, so 
as to be much higher after receding two miles than now. ‘The dip of 
the rocks to the south is stated at 0° 17’ or 25 feet to the mile, near the 
Queenstown heights, or 0° 10’, or 15 feet to the mile, from the present 
position of the falls to Lake Erie.
