plays six of the footmarks from Bexhill ; the five consecutive marks 

 are the first five of the hne a a, and the sixth mark is the single 

 ichnite (/c) crossing the track a a, at right angles between the fourth 

 and fifth marks. In consequence of a fissure which passed longitu- 

 dinally through the inner toe of the fourth mark and the outer toe 

 of the fifth, the former was divided in two and the surface of the 

 latter destroyed, in their transit from Bexhill to St. Leonard's ; 

 fortunately, however, the impressions were deep, and the integrity of 

 both prints was preserved. Such was the incoherence of the stone, 

 from the quantity of absorbed salt water, that a large amount of 

 manual labour proved insufficient to remove it without producing the 

 fractures now observed on its surface, and it was only after a slow 

 process of drying that it acquired sufficient cohesion for its removal 

 to town. 



Series of Footprints No. 2. 



The next place that contributes to the evidence is half a mile to 

 the west of Bexhill and opposite to the Tower No. 47. Here tracks 

 of impressions were so distributed over a sui'face of many hundred 

 square yards as to yield neither in numbers nor interest to the pre- 

 ceding series. I have not had an opportunity of seeing this spot 

 entirely free from loose sand, but tracks consisting of 2, 3, 5, 7, 

 and 8 impressions were distinctly traceable, and some of them, con- 

 tinuing into lines of much greater length, no doubt traversed this 

 extensive area in every direction. 



One track deviated from a right line ; but, vnth the exception of 

 two extraordinary consecutive impressions, the ichnites here presented 

 no new feature, either in form, size, or stride*. The important ex- 

 ceptions were almost of incredible dimensions ; the largest, of wliich 

 I obtained a specimen, measuring nearly 27 inches in length by 

 nearly 24 in breadth, with a stride of 42 inches. The distal extre- 

 mity of the ungual joint of the outer toe of each impression was 

 more pointed than that of the inner, and turned inside of its axis, — 

 peculiarities that I have observed in the best casts. 



In my collection is a fine natural cast from Galley Hill ; a portion 

 of the middle toe is wanting, but the cast measures 23 inches from 

 the tip of the heel to the tip of the outer toe ; so that, by analogy, 

 the extreme length of this splendid specimen must have been 27 

 inches, or of the size of those to the west of Bexhill. 



Three disconnected impressions occurred some time smce not far 

 from Bexhill, on a ledge too narrow for two consecutive marks ; one 

 of these impressions measured 28 inches in length by 25 inches in 

 breadth between the extremities of the lateral toes, proportions that 

 greatly surpass in magnitude those of the most colossal footprints of 

 the Triassic epochf . 



* In some impressions, particularly in a series to the west of Bexhill, the toes 

 appear to be connected by intenening stone which suggests the idea of a web- 

 footed animal ; but this peculiaiity is susceptible of other explanation. 



t The Brontozoum c/iganteum, or colossal biped that produced the largest triassic 

 footprints, is supposed to have been four or five times the size of the large African
