In the eye of the Cat, the pupil is perpendicularly oval, extending from above downwards, and when contracted appears like a straight line. This conformation is suited to the habits of these animals, for they are not content with prowling along the ground, but occasionally spring to great heights, their heads being directed upwards, and their eyes placed in front and more nearly parallel. This structure of the eyes occurs in all the Cat tribe. [Illustration: THE WILD CAT. (_Felis Catus._)] THE WILD CAT is a native of the forests of Europe, and was formerly abundant in Britain, but is now confined to some of the wilder parts of this country. It is a stouter and more powerful animal than the domestic Cat, and is of a greyish colour with black stripes, something like an ordinary tabby. It is a fierce creature, and is very destructive to birds and small quadrupeds. THE DOG. (_Canis familiaris._) TO no animal is mankind so much indebted for its services and affection as to the Dog. Among all the various orders of brute creatures, none have hitherto been found so entirely adapted to our use, and even to our protection, as this. There are many countries, both of the old and new continent, in which, if man were deprived of this faithful ally, he would unsuccessfully resist the foes that surround him, seeking opportunities to encroach upon his property, destroy his labour, and attack his person. His own vigilance, in many situations, could not secure him, on the one hand, against their rapacity, nor, on the other, against their speed. The Dog, more tractable than any other animal, conforms himself to the movements and habits of his master. His diligence, his ardour, and his obedience are inexhaustible; and his disposition is so friendly, that, unlike every other animal, he seems to remember only the benefits he receives: he soon forgets our blows; and instead of discovering resentment while we chastise him, exposes himself to torture, and even licks the hand from which it proceeds. Dogs, even of the dullest kind, seek the company of other animals; and by instinct take to the care of flocks and herds. THE SHEPHERD’S DOG.
