elevation belonging to the Alleghany range, in a coarse-grained sand- 

 stone, are eight remarkable impressions, all having the same dimen- 

 sions, the same distance apart, and forming a continuous series in a 

 slightly bent line. Each is of an ovoidal form, 13 inches long, 

 9 broad, and from 3 to 6 deep. The impression is deep and ovoidal 

 before, but superficial behind, as though made by an animal with a 

 long and flexible pastern. 



Twenty-seven miles from Greensburgh, on the summit of Chesnut 

 ridge, in a coarse-grained sandstone, are numerous imprints, as per- 

 fect as they are anomalous and remarkable. These imprints are of 

 different kinds : the greatest number seem to have been made by 

 ruminant mammals, as the feet were cleft so as to resemble those of 

 the ox and deer, but much larger. They are of various sizes, and 

 differ from most living types in having two hind hoofs, which made 

 deep and vivid impressions from one to two inches behind the main 

 track. 



The length of the largest, including the posterior imprints, is 9 

 inches, breadth 5^ inches. 



The smaller vary from 4^ to 5|- inches in length, by 2^ to 4|- in 

 breadth. The general form of these foot-marks is ovoidal, the largest 

 portion being behind as well as the widest part of the cleft. The 

 posterior impressions are each about the size of a walnut. The in- 

 terval between each foot-mark is about 2^ feet in the larger, and 

 18 inches in the smaller. 



Besides these, and a few others which are identical or nearly so 

 with some which I have already described on a former occasion, there 

 are four or five huge imprints of a still more remarkable character 

 than any that have heretofore met my eye. They are in a conti- 

 nuous line : each imprint is 13 inches long and 9 wide. The toes, 

 which are five in number, are thick and very perfect. Four of these 

 imprints are quite perfect, others are less so, and many are nearly 

 obliterated. The average distance between each impression is 3 feet 

 7 inches, with the exception of the last two, which are 7 feet apart. 

 This seems to indicate that there was once a track between these 

 two, which has been defaced by the erosive action of the elements 

 upon the rock during a series of ages. — Proceedings of the Acad. Nat.
