in this important branch of science, and that the day may 

 not be far distant when the movement of these great 

 storms will be thoroughly understood, and, by the aid of 

 the telegraph, their course and extent will be anticipated, 

 resulting in incalculable benefit to the mariner and the 

 iarmer. 



Cleveland, March 5, 1858. 



The Academy met at the Medical College, Col. Charles 

 Whittlesey, Vice President, in the chair. 



The minutes of the previous meeting were read and 

 approved. 



Col. Whittlesey exhibited maps of several of the Eastern 

 and Western States, on which were sketched the limits of 

 the drift and the direction of the striae, supposed to be cut 

 by glacial action. The Colonel stated that these striae are 

 to be found beneath the level of the Lake, and on the tops 

 of the highest hills. On hard trap rocks they are very fine 

 and sharply cut, while in the softer strata they are some- 

 times from two to eight inches in depth. Several specimens 

 from the limestone rock, at Sandusky, were shown, and on 

 these the lines were quite distinct, and exhibited the phe-

 angles with each other, and giving the stone a checkered 

 appearance. 



After considerable discussion, the meeting adjourned for 



two weeks.
