the one below ; while the matter of this under one, escaping as 

 it were from this pressure, had been forced up round the an- 

 terior margin of the foot, and produced a hollow impression on 

 the under side of the incumbent layer. 



A few yards to the north of the tracks already described, 

 there was a third, in which the footmarks were all filled up and 

 elevated rather than depressed, though the general outline was 

 perfectly distinct. One row of them, indeed, was much more 

 distinct than the rest ; for it seemed as if at this place two or 

 three animals of the same species had descended in succession, 

 at some distance of time from each other. The shape of the 

 footmarks was a blunt oval about 1| inch in length, and those 

 on each side were not more than 3| inches asunder, while the 

 distance of the one side from the other did not much exceed 

 1| inch. Of these a very good specimen was obtained, the 

 thickness of the containing layer being at this place nearly equal 

 to that of thin pavement. 



The separate track at the north extremity of the range was 

 that of an animal still smaller than the one last mentioned, and 

 whose foot was more circular. Here too more than one animal 

 had passed along. The impressions were very numerous, and 

 could be traced from the earthy belt on which we stood up to 

 the very outgoing of the stratum ; but besides being probably 

 slight at first, they had all been so completely filled up with a 

 sandy sediment, exactly similar to the rest of the rock, as not 

 to afford any specimen that would have been of much value, 

 when unconnected with others, or with the series to which it 

 belonged. 



It will be obvious, from the preceding description of the 

 stratum containing these animal impressions, that though now 

 lying bare and superficial as at the time when these impressions 

 were made, it is really the one on which all the other strata of 

 the quarry had been superimposed. It may be proper to state, 

 too, that though the tracks here described are at the upper part- 

 of the acclivity, one of the specimens belonging to Dr Duncan, 

 which contains the deepest and most distinct impressions that 

 have yet been discovered, was found at the base of the stra- 

 tum, in the lower part of the quarry, perhaps 60 or 70 feet 

 beneath the surface of the earth. In what manner the facts
