398 Miscellanies. 
The casts, which consists of a rather soft and coarse sandstone, 
were evidently formed in the impressions of two hind feet; and 
though they have suffered from exposure to the weather for twelve 
years, yet they are sufficiently perfect to have enabled Sir Philip Eger- 
ton to take the measurements of the different parts, and draw up the 
accompanying comparative table. Itis necessary to state, that though 
he preserves the use of the term thumb for the convenience of com- 
parison with previous descriptions, yet he is of opinion that the mar- 
ginal digit which has been so designated, is not the representative of 
the fifth, but of the first toe.

From these measurements it appears, that considerable differences 
exist in the three specimens of Chirotherium. Upon comparing the 
footstep from Hessberg with that from Storeton, it will be found, that 
the former is thicker and more clumsy than the latter; that the sole 
is shorter and broader, and the toes wider and longer. The most im- 
portant discrepancy, however, is in the position of the thumb, which 
is placed much nearer the heel in the Hessberg specimens than in 
those from Storeton. The cast from near Tarporley resembles the 
latter more than the former; it nevertheless differs considerably in 
the proportion of the breadth to the length of the sole, which is 
greater; and in the proportions of the length of the toes to the length 
of the sole, which is less than in the Storeton specimens. It is also 
distinguished by the greater divergence of the toes from each other. 
From these differences and the gigantic size of the Tarporley spe 
cimen, the author conceives that the animal which made the im- 
pression was a distinct species; and he proposes for it, in compli- 
ance with the adage ex pede Herculem, the name of Chirothertum 
Herculis.—Lond. and Edin. Phil. Mag., Jan., 1839.
