as assured by the
superintendent, that when young it had shoulder-stripes, and faint
stripes on its flanks and legs. I mention this case more especially as
an instance of the stripes being much plainer during youth than in old
age.

As the zebra has such conspicuously striped legs, it might have been
expected that the hybrids from this animal and the common ass would
have had their legs in some degree striped; but it appears from the
figures given in Dr. Gray's 'Knowsley Gleanings,' and still more
plainly from that given by Geoffroy and F. Cuvier,[98] that the legs
are much more conspicuously striped than the rest of the body; and this
fact is intelligible only on the belief that the ass aids in giving,
through the power of reversion, this character to its hybrid offspring.

The quagga is banded over the whole front part of its body like a
zebra, but has no stripes on its legs, or mere traces of them. But in
the famous hybrid bred by Lord Morton,[99] from a chesnut, nearly
purely-bred, Arabian mare, by a male quagga, the stripes were "more
strongly defined and darker than those on the legs of the quagga." The
mare was subsequently put to a black Arabian horse, and bore two colts,
both of which, as formerly stated, were plainly striped on the legs,
and one of them likewise had stripes on the neck and body.

The _Asinus Indicus_[100] is characterised by a spinal stripe, without
shoulder {43} or leg stripes; but traces of these latter stripes may
occasionally be seen even in the adult;[101] and Colonel S. Poole, who
has had ample opportunities for observation, informs me that in the
foal, when first born, the head and legs are often striped, but the
shoulder-stripe is not so distinct as in the domestic ass; all these
stripes, excepting that along the spine, soon disappear. Now a hybrid,
raised at Knowsley[102] from a female of this species by a male
domestic ass, had all four legs transversely and conspicuously striped,
had three short stripes on each shoulder, and had even some zebra-like
stripes on its face! Dr. Gray informs me that he has seen a second
hybrid of the same parentage similarly striped.

From these facts we see that the crossing of the several equine species
tends in a marked manner to cause stripes to appear on various parts of the
body, especially on the legs. As we do not know
