256 Tracks of Animals in Variegated Sandstone. 
looking for foot-prints here, nor recognized these when accident- 
ally found, as such. 
The form of these foot-reliefs, which resemble those of Hild- 
burghausen in no other respect than the mode of their occurrence, 
is very peculiar, being two-toed, and more like horse-shoes than 
feet. I sought in vain for any regular arrangement. or the con- 
tinuous course of any one individual ; all the tracks stood singly, 
as in the above plate A, in as much disorder as if there had beet 
a large tumultuous assemblage of animals there. For this reason, 
the forms of individual casts are often not expressed entire, and 
all are not alike, some being rounded behind, (2, 3, 7 and §,) and 
others more angular, (1, 4 and 5;) sometimes we observe on the 
hind part a little irregular prominence, (5 and 6.) ‘These vane 
tions may have arisen, in part, though hardly all of them, from 
the inequality of the soft ground, from the impression and dl- 
rection of the foot, &c. The irregular position speaks rather 
for two-footed than four-footed animals. Some slabs are covered 
with little round bosses of the same size with the foot-casts; 
these, however, occur only on the under surface of the layers rest- 
ing on the clay. Could the clay, ina certain state of softness, 
have on the feet so as to make their prints obscure?
