180 Intelligence and Miscellanies. 



At the shore of the Bay, where as before observed, it 

 turns abruptly to the south, the liated rock again makes its 

 appearance, running in the same direction. Here the rock 

 dips gently to the east, and disappears with the impressions 

 under the water of the Bay. From the most westerly point 

 where I observed the impressions, to this place, must be 

 more than one mile, there can be no doubt that it is contin- 

 ued ai) that distance ; how much farther west or east it may 

 extend is unknown. 



It has to me the appearance of having been formed by 

 the powerful and continued attrition of some hard body. 

 It resembled in some slight degree, the sides of a saw gate, 

 (if you understand the expression) which has been for a long 

 time rubbing against the posts, which confine and direct it. 

 It was said to have been observed, by the gentleman before 

 alluded to, that the cause of this phenomenon had been the 

 subject of various conjectures in Europe ; but that the bet- 

 ter opinion seemed to be, that it had been effected by the 

 operation of running water. Such an opinion, however, 

 I think, could never have been formed, by one who had 

 himself examined this appearance; for to me, it does not 

 seem possible that water under any circumstances, could 

 have effected it. The flutings in width, depth, and direc- 

 tion, are as regular as if they had been cut out by a grooving 

 plane. This, running water could not efTect, nor could its 

 operation have produced that glassy smoothness, which, in 

 many parts, it still retains.

Observations upon the Cadmia found at the Ancram iron

In the second number of the first volume of the New- 

 York Medical and Physical Journal, Dr. Torrey has pub- 

 lished a description and analysis of a substance, which he 

 considered as a .ew mineral, and for which he proposed 

 the name of green oxide of zinc; a specimen of this sub- 

 stance having been handed to me last spring, I immediately
