INDIVIDUAL DIFFERENCES 
acquainted with the subject would doubt the possibility 
of each one being readily distinguished and called by 
name at sight ; yet such is the fact, and it only requires 
a little care and attention to notice not only peculiarities 
in features, but marked differences in liahits, disposition, 
temper, and mode of action. How many thoroughbred 
and carefully reared and trained hounds are found to 
skulk and avoid the hard work of the chase, and look out 
for the most favourable opportunity of sneaking out of 
sight, and a hundred other tricks and dodges resorted to 
by cunning dogs, both old and young. It may be said 
that the dog and the sheep being domesticated animals, 
it is unfair to introduce them to illustrate a subject that 
is more strictly intended to show the individual differences 
that exist among wild species of animals. This must be 
admitted to be so far true, and the only object of their 
introduction is to point out that in the animals of pure 
breed, and consequently as much alike in appearance as 
wild animals, when closely examined are found to exhibit 
marks of distinction, not so easily observable on account 
of the difficulty of the examination of wild animals, and 
not because they do not exist. As an example, we may 
say, for instance, if the living lions to be found in the 
numerous menageries and Zoological Gardens in Europe 
had their portraits painted, these monarchs of the forest 
(as they are commonly called) would be found to differ 
in features and expression quite as much as the emperors, 
kings, and other rulers of this our savage world. 
But to return more closely to the subject under con- 
sideration, let us take the various kinds of wild birds that 
are reared by hand from the nest ; it would be natural 
to expect that the five or six young birds hatched from 
the same parents and fed at the same time, and upon the 
same food, treated alike, and kept together under the
