the right leg, were eaten. Since that time he has not attacked any 
other part of his body. He now walks on three legs, but with great 
difficulty.” The fact seems to be, that many animals, particularly 
the monkey tribe, when in confinement, are subject to a sort of 
itching, which induces them to nibble their extremities; and in the 
case of monkeys, especially their tails, and that they rarely cease 
until mortification and death ensue *. 
A large proportion of the hyaenas’ teeth bears marks of extreme 
old age, some being abraded to the very sockets by continual gnawing, 
and the majority having lost the upper portion of their coronary part, 
and having fangs extremely large: these probably died in the den 
from mere old age : and if we compare the lacerated condition of the 
bones that accompany them, with the state of the teeth thus worn 
down to the very stumps, notwithstanding their prodigious strength, 
we find in the latter the obvious instruments by which the former 
were thus comminuted. A great number of other teeth appear to 
have belonged to young hyaenas (see Plate VI. figs. 15 to 27), being 
of the first set or milk teeth; in many others of the second set the 
fangs are not developed, and the points and edges of the crown not 
the least worn. I have a fragment of the lower jaw, in which the 
second set of teeth had not been protruded, but were in the act of 
forming below the first. (See Plate V. fig. 3 , 4.) Mr. Salmond has an 
entire one. (See Plate XXIII. fig. 10.) Archdeacon Wrangham has a 
* Pennant, in his Zoology, (3rd edit. 4to. vol. 1, p. 305) speaking of the Caspian 
Lynx, mentions one which bit off and devoured one of its own fractured limbs. Rats 
and foxes, when caught in traps, are often known to bite off their wounded limbs, but I 
have not heard of their devouring them.
