DRO) Animal Life 
different forms and habits of their possessors, and when thus considered they furnish 
marked indications as to certain very constant muscular actions of an animal’s life, 
and especially those which subserve locomotion; indeed, in another account which I 
have given of them, I ventured to call certain of them “animal pedometers,” because 
of their close connection with the range and constancy of 
the locomotive lives of animals. They are found chiefly 
among ungulates, and of these the domestic horse is in the 
proud position of exhibiting a greater number of these 
registers of locumotive activity than any other animal, wild or 
domesticated. A horse displays on its coat constantly three 
and very commonly five more of these whorls, featherings and 
crests. In this case, as in others, the greater mcludes the less, 
and no animal is to be found carrying about such badges on 
its coat which have not their corresponding arrangement on the 
skin of a domestic horse. So, for a type-study of this part 
of our subject, the friend and servant of man is most valuable. 
He is to us almost as useful, in our humble matters, as 
the lancelet of revered memory to the zoological teacher in his 
class-room. The curious fact that the horse possesses so many 
of these phenomena would require from the uncompromising 
selectionist some highly transcendental explanations, if indeed he 
thought this small waste-land of the territory of science worth 
claiming. But let us once adopt the working hypothesis that 
the facts in question are produced by very-often-repeated 
muscular movements, and soon we find the observed phenomena 
fall into ne, and order takes the place of chaos. The 
domestic horse, it must always be remembered, is 
essentially a locomotive, though not made of iron, steel 
and brass. Other wild ungulates, especially other Hquide, 
may be as fleet of foot; indeed the kiang and onager 
are said to outpace a very fast horse. But these wild 
members of the Equide are not such fools as to spend 
a large part of their lives running about on behalf of 
man. They can gallop like a racehorse when occasion 
requires, but rapid locomotion is to them a matter 
of casual need, often a very imperious one while it lasts, 
for their own ssafety. It is not, however, imposed upon 
them by the will of a superior being, who is very 
inferior in his own locomotive powers—indeed he has on 
that account learnt how to make the muscles of other 
animals work at the bidding of his superior brain. 
This contrast between a domestic horse and a wild 
member of the Equide is graphically illustrated by the 
observation, first, of a common horse’s skin, and then of 
that of a zebra. Yet these two equines are so alike, 
except for their coloration, that if both were skinned 
j no one but a traimed anatomist could distinguish the 
carcases of the two animals. And yet what different 
evidence do they not give by their hair-slope as to their locomotive lives. The horse 
shows three constantly and five very commonly of these registers of work done, in the 
shape of whorls, featherings and crests, whereas zebras show on their whole body
