placed close together, being very small, and seeming scarce separated; so that with respect to this part of its formation, the animal has some resemblance to the viper. However, it is a very harmless, little creature, doing scarce any injury. On the contrary, as it lives chiefly in the fields, and feeds more upon insects than corn, it may be considered rather as a friend than an enemy. It has a strong disagreeable smell, so that the cat, when it is killed, will refuse to eat it. It is said to bring four or five young at a time.*

THE DORMOUSE.— These animals may be distinguished into three kinds : the greater dormouse, which Buffon calls the Loir; the middle, wbicb he calls the Lerot; the less, which he denominates the Muscardin. They differ from each other in size, the largest being equal to a rat, the least being no bigger than a mouse.

They inhabit woods or very thick hedges, forming their pests in the hollow of some tree, or near the bottom of a close shrub, humbly content with continuing at the bottom, and never aspi. ring to sport among the branches. Towards the approach of the cold season they form a little magazine of nuts, beans, or acorns; and, having laid in their hoard, shut themselves up with it for the winter. As soon as they feel the first advances of the cold, they

(Muscardin Mouse.) prepare to lessen its effect, by rolling themselves up in a ball, and thus exposing the smallest surface to the weather. But it often happens that the warmth of a sunny day, or an accidental change from cold to heat, thaws their `nearly stagnant fluids, and they revive. On such occasions they have their provisions laid in, and they have not far to seek for their support. In this manner they continue usually asleep, but sometimes waking, for above five months in the year, seldom venturing from their retreats,

and consequently but rarely seen.* Their nests are lined with moss, grass and dead leaves; they usually bring forth three or four young at a time, and that but once a year, in the spring.

THE MUSK RAT.-of these animals of the rat kind, but with a musky smell, there are also three distinctions, as of the former; the Ondatra, the Desman,

BE and the Pilori. The Ondatra is a native of Canada, the Desman of Lapland, and the Pilori of the West-India islands. The ondatra differs from all others of its kind, in having the tail flatted and carried edgeways. The desman has a long extended snout like the shrew-mouse; and the pilori a short tail, as thick at one end as the

(Musk Rat.) other. They all resemble each other in being fond of the water, but particularly in that musky odour from whence they have taken their name.

Of these, the ondatra is the most remarkable, and has been the most minutely described. (g) This animal is about the size of a small rabbit, but has the hair, the colour, and the tail of a rat, except that it is flatted on the sides, as mentioned above. But it is still more extraordinary upon other accounts, and dif ferent from all other animals whatever. It is so formed that it can contract and enlarge its body at pleasure. It has a muscle like that of horses, hy which they move their hides, lying immediately under the skin, and that furnished with such a power of contraction, together with such an elasticity in the false ribs, that this animal can creep into a hole where others, seemingly much less, cannot follow. The female is remarkable also for two distinct apertures, one for urine, the other for propagation. The male is equally observable for a peculiarity of conformation; the musky smell is much stronger at one particular season of the year than any other; and the marks of the sex seem to appear and disappear in the same manner.

The ondatra in some measure resembles the beaver in its nature and disposition. They both live in society during winter; they both form houses of two feet and a half wide, in which they reside several families together. In these they do not assemble to sleep as the marmot, but purely to shelter themselves from the rigour of the season. However, they do not lay up magazines of provision like the beaver; they only form a kind of covert way to and round their dwelling, from whence they issue to procure water and roots, upon which they subsist. During winter their houses are covered under a depth of eight or ten feet of snow; so that they must lead but a cold, gloomy, and a necessitous life, during its continuance. During summer they separate two hy two, and feed upon the variety of roots and vegetables that the season offers. They then become extremely fat, and are much sought after, as well for their flesh as their

skins, wbich are very valuable.* They then also acquire a very strong scent of musk, so pleasing to an European, but which the savages of Canada cannot abide. What we admire as a perfume, they consider as a most abominable stench, and call one of their rivers, on the banks of which this animal is seen to burrow in numbers, by the name of the stinking river, as well as the rat itself, wbich is denominated by them the stinkard. This is a strange diversity among mankind; and, perhaps, may be ascribed to the different kinds of food among different nations. Such as chiefly feed upon rancid oils and putrid Besh, will often mistake the nature of scents; and, having been long used to ill smells, will by babit consider them as perfumes. Be this as it will, although these nations of northern savages consider the musk rat as intolerably fætid, they nevertheless regard it as very good eating ; and, indeed, in this tbey imitate the epicures of Europe very exactly, whose taste seldom relishes a dish till the nose gives the strongest marks of disapprobation. As to the rest, this animal a good deal resembles the beaver in its habits and disposition; but, as its instincts are less powerful, and its economy less exact, I will reserve for the description of that animal a part of what may be appliable to this.

THE CRICETUS.—The cricetus, or German rat, which Buffon calls the Hamster, greatly resembles the water-rat in its size, small eyes, and the shortness of its tail. It differs in colour, being rather browner, like the Norway rat, with the belly and legs of a dirty yellow. But the marks by which it may be distinguished from all others, are two pouches, like those of a baboon, on each side of its jaw, under the skin, into which it can cram a large

(llamsler.) quantity of provision. These bags are oblong, and of the size, when filled, of a large walnut. They open into the mouth, and fall back along the neck to the shoulder. Into these the animal can thrust the surplus of those fruits or grains it gathers in the fields, such as wheat, peas, or acorns. When the immediate calls of hunger are satistied, it then falls to filling these ; and thus, loaded with two great hunches on each side of the jaw, it returns home to its bole to deposit the spoil as a store for the winter. The size, the fecundity, and the voraciousness of this animal render it one of the greatest pests in the countries where it is found, and every method is made use of to destroy it.

But, although this animal is very noxions with respect to man, yet, considered with regard to those instincts which conduce to its own support and convenience,

it deserves our admiration. (8) Its hole offers a very curious object for contem. plation, and shows a degree of skill superior to the rest of the rat kind.* It consists of a variety of apartments fitted up for the different occasions of the little inhabitant. It is generally made on an inclining ground, and always has two entrances, one perpendicular and the other oblique; though, if there be more than one in a family, there are as many perpendicular boles as there are individuals below. The perpendicular hole is usually that through which they go in and out: the oblique serves to give a thorough air to keep the retreat clean, and, in case one hole is stopped, to give an exit at this. Within about a foot of the perpendicnlar hole, the animal makes two more, where are deposited the family's provisions. These are much more spacious than the former, and are large in proportion to the quantity of the store. Beside these, there is still another apartment warmly lined with grass and straw, where the female brings forth her young; all these communicate with each other, and all together take up a space of ten or twelve feet in diameter. These animals furnish their storehonses with dry corn well cleaned; they also lay in corn in the ear, and beans and peas in the pod. These, when occasion requires, they afterwards separate, carrying out the pods and empty ears by their oblique passage. They usually begin to lay in at the latter end of August; and, as each magazine is filled, they carefully cover up the mouth with earth, and that so neatly that it is no easy matter to discover where the earth has been removed. The only means of finding out their retreats are, therefore, to observe the oblique entrance, wbich generally has a small quantity of earth before it; and this, though often several yards from their perpendicular retreat, leads those who are skilled in the search to make the discovery. Many German peasants are known to make a livelihood by finding out and bringing off their boards, which, in a fruitful season, often furnish two bushels of good grain in each apartment.

Like most others of the rat kind, they produce twice or thrice a year, and bring five or six at a time.

THE LEMMING.–Having considered various kinds of these noxious little animals that elude the indignation of mankind, and subsist by their number, not their strength, we come to a species more bold, more dangerous, and more numerous than any of the former. The lemming, which is a native of Scandinavia, is often seen to pour down in myriads from the northern mountains, and, like a pestilence, destroy all the productions of the earth. It

(Lemming.) is described as being larger than a dormouse, with a bushy tail, though shorter. It is covered with thin hair
