Of these caves the work before us contains several remarkable details, particularly of one at Kirkdale in Yorkshire, where the bones of hyænas, tigers, bears, wolves, foxes, weasels, elephants, rhinocerosses, hippopotamusses, horses, oxen, deer, hares, rabbits, rats, mice, ravens, pigeons, and other birds were found, indiscriminately dispersed in a sediment of loam, all bearing the trace of having been gnawed, with marks, corresponding to those of hyænas’ teeth, those parts of bones only being left, which hyænas are observed to spare, and the very excrement of these ferocious animals being detected among other remains, dispersed in the mud.
