CAVE ANIMALS ALLIED TO PRESENT KINDS. 101 
ed, that other animals obey a contrary rule ; some 
teeth of a species of horse are gigantic as compared 
to the generality of living instances, the fragment 
of hare’s skull which I found at Kitley cavern must 
have belonged to a much larger animal than our 
lepus timidus, and the parts of the hyzena’s skull 
contrasted with a cast of our Cape hyzna’s im- 
presses the mind with the terrific force the former 
species must have possessed in its masticatory 
apparatus beyond that of the latter,* so that alto- 
gether the rule of diminutives is far from being 
inviolate. 
* M. Cuvier, says the hyena fossilis was one third larger than 
our present species allied to it, but so far as my own comparison 
of these species goes, I should imagine the difference had been 
rather over-estimated by him.—The elephantine teeth from the 
Yealm Bridge Cave on the other hand, due perhaps to nearly 
full-grown animals, are absolutely diminutive in comparison with 
those of recent species. (see woodcuts.)
