dually advance towards perfection. But we find that they never vary in the least from the rules of their forefathers, never deviate from the circle prescribed to them by nature, and the beavers of to-day build exactly after the same plan as those which lived before the deluge. But they are not the less worthy of our admiration. In these sagacious creatures we have an example of the great diversity there is in the instinct of animals-how superior is the instinct of the beaver to that of the sheep!

The flesh of the anterior part of the bodies of beavers re sembles that of land animals in substance and flavour; while that of the lower possesses the taste, and smell, and lightness of fish.

The sexual union among these animals is connected with considerable individual choice, sentiment, and constancy.Every couple pass together the autumn and winter, with the most perfect comfort and affection. About the close of winter, the females, after a gestation of four months, produce, in general, each two or three young, and soon after this period they are quitted by the males, who ramble into the country to enjoy the return of spring; occasionally returning to their cabins, but no longer dwelling in them. When the females have reared their young, which happens in the course of a few weeks, to a state in which they can follow their dams, these also quit their winter residence, and resort to the woods, to enjoy the opening bloom and renovated supplies of nature. If their habitations on the water should be impaired by floods, or winds, or enemies, the beavers assemble with great rapidity to repair the damage. If no alarm of this nature occurs, the summer is principally spent by them in the woods, and on the advance of autumn they assemble in the scene of their former labours and friendships, and prepare with assiduity for the confinement and rigours of approaching winter.

When taken young, the beaver may be tamed without difficulty; but it exhibits few or no indications of superior intelliSome beavers are averse to that association which so strikingly characterizes these animals in general, and satisfy themselves with digging holes in the banks of rivers, instead of erecting elaborate habitations. The fur of these is comparatively of little value.

Another subject of animal curiosity 18, THE MOLE.-This animal is about six inches in length, without the tail Its body is large and cylindrical, and its snout strong and cartilaginous. Its skin is of extraordinary thickness, and covered with a fur, short, but yielding to that of no other animal in fineness. It hears with particular acuteness, and, notwithstanding the popular opinion to the contrary, possesses eyes.

which it is stated to be able to withdraw or project at pleasure It lives partly on the roots of vegetables, but principally on animal food, such as worms and insects, and is extremely voracious and fierce. Shaw relates, from Sir Thomas Brown, that a mole, a toad, and a serpent, have been repeatedly inclosed in a large glass vase, and that the mole has not only killed the others, but has devoured a very considerable par of them. It abounds in soft ground, in which it can dig with ease, and which furnishes it with a great supply of food. I forms its subterraneous apartments with great facility by its snout and feet, and with a very judicious reference to escape and comfort. It produces four or five young in the spring, in a nest a little beneath the surface, composed of moss and herbage. It is an animal injurious to the grounds of the farmer, by throwing up innumerable hills of mould, in the construction of its habitation, or the pursuit of its food, and many persons obtain their subsistence from the premiums, which are, on this account, given for their destruction. Moles can swim with considerable dexterity, and are thus furnished with the means of escape in sudden inundations, to which they are frequently exposed. In Ireland, the mole is unknown.

THE COMMON FROG.-This is an animal so well known, that it needs no description: but some of its properties are very singular. Its spring, or power of taking large leaps, is remarkably great, and it is the best swimmer of all four-footed animals. Its parts are finely adapted for those ends, the fore members of the body being very lightly made, the hind legs and thighs very long, and furnished with very strong muscles. While in a tadpole state, it is entirely a water animal, for in this element the spawn is cast. As soon as frogs are released from their tadpole state, they immediately take to land; and if the weather has been hot, and there fall any refreshing showers, the ground for a considerable space is perfectly blackened by myriads of these animalcules, seeking for some secure lurking places. Some persons not taking time to examine into this phenomenon, imagined them to have been generated in the clouds, and showered on the earth but had they, like Mr. Derham, traced them to the next pool, they would have found a better solution of the difficulty. As frogs adhere closely to the backs of their own species, so we know they will do the same by fish. That they will injure, if not entirely kill carp, is a fact indisputable, from the following relation.

Not many years ago, on fishing a pond belonging to Mr. Pitt, of Encomb, Dorsetshire, great numbers of the carp were found, each with a frog mounted on it, the hind legs clinging to the back, and the fore legs fixed to the corner of

ench eye of the fish, which were thin and greatly wasted, teased by carrying so disagreeable a load. The croaking of frogs is well known; and from that, in fenny countries, they are distinguished by ludicrous titles,-thus they are styled Dutch nightingales, and Boston waites. Yet there is a time of the year when they become mute, neither croaking nor opening their mouths for a whole month; this happens in the ho season, and that is in many places known to the country people by the name of the paddock-moon. It is said, that during that period their mouths are so closed, that no force (without killing the animal) will be capable of opening them. These, as well as other reptiles, feed but a small space of the year. Their food is flies, insects, and snails. During winter, frogs and toads remain in a torpid state; the last of which will dig into the earth, and cover themselves with almost the same agility as the mole.

its

Not less remarkable is THE COMMON TOAD.-This is the most deformed and hideous of all animals. The body is broad, the back flat, and covered with a pimply dusky hide; the belly large, swagging, and swelling out; the legs short, and pace laboured and crawling; its retreat gloomy and filthy: in short, its general appearance is such as to strike one with disgust and horror. Yet it is said that its eyes are fine. Ælian and other ancient writers tell many ridiculous fables of the poison of the toad.

This animal was believed by some old writers to have a stone in its head fraught with great virtues, medical and magical it was distinguished by the term of, the reptile, and called the toad-stone, bufonites, krottenstern, and other names, but all its fancied powers vanished on the discovery of its being nothing but the fossil tooth of the sea-wolf, or of some other flat-toothed fish, not unfrequent in our island, as well as several other countries. But these fables have been long exploded. And as to the notion of its being a poisonous animal, it is probable that its excessive deformity, joined to the faculty it has of emitting a juice from its pimples, and a dusky liquid from its hind parts, is the foundation of the report. That it has any noxious qualities, there seem to be no proofs in the smallest degree satisfactory, though we have heard many strange relations on that point. On the contrary, many have taken them in their naked hands, and held them long without eceiving the least injury. It is also well known that quacks have eaten them, and have squeezed their juices into a glass, and drank them with impunity They are also a common food to many animals; to buzzards, owls, Norfolk plovers, ducks, and snakes, which would not touch them, were they in any degree noxious.

The fullest information concerning the nature and qualities of this animal is contained in letters from Mr. Arscott and Mr. Pitfield to Dr. Milles, communicated to Mr. Pennant; concerning a toad that lived above thirty-six years with them, was completely tame, and became so great a favourite that most of the ladies in the neighbourhood got the better of their prejudices so far as to be anxious to see it fed. Its food was insects, such as millepedes, spiders, ants, flies, &c. but it was particularly fond of flesh worms, which were bred on purpose for it. It never appeared in winter, but regularly made its appearance in the spring, when the warm weather commenced, climbing up a few steps, and waiting to be taken up, carried into the house, and fed upon a table. Before it attacked the insects, it fixed its eyes on them, and remained motionless for a quarter of a minute, when it attacked them by an instantaneous motion of its tongue, darted on the insect with such rapidity that the eye could not follow it, whereby the insect stuck to the tip of its tongue, and was instantly conveyed to its mouth. This favourite toad at last lost its life, in consequence of being attacked by a tame raven, which picked out one of its eyes; and although the toad was rescued, and lived a year longer, it never recovered its health or spirit. It never showed any signs of rage, being never provoked.

Our next subject is an animal of great bulk, THE RHINOCEROS. This quadruped is exceeded in size only by the elephant. Its usual length, not including the tail, is twelve feet, and the circumference of its body nearly the same. nose is armed with a horny substance, projecting, in the fullgrown animal, nearly three feet, and is a weapon of defence, which almost secures it from every attack. Even the tiger, with all his ferocity, is but very rarely daring enough to assail the rhinoceros. Its upper lip is of considerable length and pliability, acting like a species of snout, grasping the shoots of trees and various substances, and conveying them to the mouth; and it is capable of extension and contraction at the animal's convenience. The skin is, in some parts, so thick and hard as scarcely to be penetrable by the sharpest sabre, or even by a musket-ball. These animals are found in Bengal, Siam, China, and in several countries of Africa; but are far less numerous than the elephant, and of sequestered solitary habits. The female produces only one at a birth; and at the age of two years the horn is cnly an inch long, and at six only of the length of nine inches. The rhinoceros is not ferocious, unless provoked, when he exhibits paroxysms of rage and madness, and is highly dangerous to those who encounter him. He runs with great swiftness, and rushes through brakes and woods with an energy to which every thing yields. He is

generally, however, quiet and inoffensive. Its food consists entirely of vegetables, the tender branches of trees, and succulent herbage, of which it will devour immense quantities. It delights in retired and cool situations, near lakes and streams, and appears to derive one f the nighest satisfactions from the practice of rolling and wailowing in mud.—in this respect bearing a striking resemblance to the hog.

This animal was exhibited, by Augustus, to the Romans, and is supposed to be the unicorn of the scripture, as it possesses the properties ascribed to that animal, of magnitude, strength, and swiftness, in addition to that peculiarity of a single horn, which may be considered as establishing their identity. This animal can distinguish, by its sight, only what is directly before it, and always, when pursued, takes the course immediately before it, almost without the slightest deviation from a right line, removing every impediment. Its sense of smelling is very acute, and also of hearing, and, on both these accounts, the hunters approach him against the wind. In general, they watch his lying down to sleep, when, advancing with the greatest circumspection, they discharge their muskets into his belly. The flesh is eaten both in Africa and India.

We now proceed to THE CROCODILE.-This animal is a na tive both of Africa and Asia, but is most frequently found in the former, inhabiting its vast rivers, and particularly the Niger and the Nile. It has occasionally been seen of the length of even thirty feet, and instances of its attaining that ot twenty are by no means uncommon. It principally subsists on fish, but such is its voracity, that it seizes almost every thing that comes within its reach. The upper part of its body is covered with a species of armour, so thick and firm, as to be scarcely penetrable with a musket-ball; and the whole body has the appearance of an elaborate covering of carved work. It is an oviparous animal, and its eggs scarcely exceed in size those of a goose. These eggs are regarded as luxuries by the natives of some countries of Africa, who will also with great relish partake of the flesh of the crocodile itself. When young, the small size and weak state of the crocodile prevent its being injurious to any animal of considerable bulk or strength; and those which have been brought living to England have by no means indicated that ferocious and devouring character which they have been generally described to possess; a circumstance probably owing to the change of climate, and the reducing effect of confinement.

In its native climate its power and propensity to destruction are unquestionably great, and excite in the inhabitants of the territories near its haunts a high degree of terror. It lies in
