4 LOUIS DOLLO. 
ristic bed of-the Wadhurst Clay, a subdivision of the Hastings 
Sand, or Lower Wealden. 
» It occurs near the top of the Sea Cliff between Hastings and 
Ecclesbourne Valley. 
> The bed is inaccessible from above, but larges masses of it fall, 
as a rule, during the winter months, when it is usually broken up 
for road mettle. 
» Iguanodon foot-prints, however, occur throughout the Wealden 
beds, at many horizons, but usually in relief owing to the softer 
nature of the rocks. The above mentioned bed produces the finest 
IMPreSSIONS. 
» Itis now the first time that a connected series of Iguanodont 
foot-prints has occurred in such a position as to enable them to be 
photographed. 
» The actuel surface of the rock is ripple-marked and covered 
with worm casts, coprolites and shells of Cyrena. > (CG. Dawsox). 
2. Empreintes de pied dn premier type. — « These are 
all impressions. No heel-like impression. 
> 1. Foot-print A. — Occurred on the edge of the block and 
showed distinctly three toes. 
> The bipedal stride A to C measured seven feet ten inches. 
> 2. Foot-print C. — The centre toe of this impression measured 
exactly nine inches. 
> AJ] the toes of this series terminated with a deep impression 
as if made by a sharp claw, the right of C having this feature 
specially defined. 
> 3. Foot-prints B und D. — The bipedal stride here measured 
eight feet one inch. 
> 4. Foot-print I. — I believe to belong to the same individual 
that made the impression 1, but it occurs as a natural cast, not as 
an impression. 
> This last impression is much blurred and the mud is disturbed 
as if it has been very soft, and I conjecture that the Reptile may 
have, by instinct, down the next foot (1) flatter in consequence and 
lowered the tail (Q). > (C. Dawson),
