We may say that an "instinctive" movement is a vital movement performed by an animal the first time that it finds itself in a novel situation; or, more correctly, one which it would perform if the situation were novel.* The instincts of an animal are different at different periods of its growth, and this fact may cause changes of behaviour which are not due to learning.
On the other hand, a movement is "learnt," or embodies a "habit," if it is due to previous experience of similar situations, and is not what it would be if the animal had had no such experience.
"If the animals
in front are continually changing and the direction of the whole herd is constantly altered, this is because in order to follow a given direction the animals
transfer their will to the animals
that have attracted our attention, and to study the movements of the herd we must watch the movements of all the prominent animals
moving on all sides of the herd." So say the third class of historians who regard all historical persons, from monarchs to journalists, as the expression of their age.
"Undoubtedly," replied the captain, "if it possesses such dreadful power, it is the most terrible animal that ever was created.
Notwithstanding the distance, and the noise of the wind and sea, one heard distinctly the loud strokes of the animal's tail, and even its panting breath.
And though there was no reason in his brain for a clear conception of so abstract a thing as justice, nevertheless, in his own way, he felt the justice of the man- animals, and he knew them for what they were--makers of law and executors of law.
It is not given us to know how some animals know laughter, and know when they are being laughed at; but it was this same way that White Fang knew it.
Among them were the teeth of a gnawer, equalling in size and closely resembling those of the Capybara, whose habits have been described; and therefore, probably, an aquatic animal. There was also part of the head of a Ctenomys; the species being different from the Tucutuco, but with a close general resemblance.
 From the bones of the Scelidotherium, including even the knee-cap, being intombed in their proper relative positions, and from the osseous armour of the great armadillo-like animal being so well preserved, together with the bones of one of its legs, we may feel assured that these remains were fresh and united by their ligaments, when deposited in the gravel together with the shells.
This condition continued for seven days; his animals, however, did not leave him day nor night, except that the eagle flew forth to fetch food.
Then did his animals think the time had come to speak unto him.
Again, all recent experience shows that it is most difficult to get any wild animal to breed freely under domestication; yet on the hypothesis of the multiple origin of our pigeons, it must be assumed that at least seven or eight species were so thoroughly domesticated in ancient times by half-civilized man, as to be quite prolific under confinement.
When we look to the individuals of the same variety or sub-variety of our older cultivated plants and animals, one of the first points which strikes us, is, that they generally differ much more from each other, than do the individuals of any one species or variety in a state of nature.
Difficult as this is to accomplish, it is still more difficult to persuade the human into any organised effort to alleviate the ill conditions of the lesser animals
"John, how can you expect sick people to come and see you when you keep all these animals
in the house?
