The shrew mouse (_fig. 81._) seems to form a shade in the order of small animals, and to fill up the interval between the rat and the mole, which though they resemble each other in size, differ greatly in form, and are a totally distinct species. The shrew is smaller than the common mouse, resembles the mole in its snout, which is longer than the jaw-bones; in its eyes which, though larger than those of the mole, are in the same manner concealed, and smaller than those of the mouse; in the number of its toes, having five on each foot, in its tail and legs, particularly the hind ones, which are shorter than those of the mouse; in its ears, and lastly, in its teeth. This extremely little creature has a strong smell peculiar to itself, and so offensive to cats, that though they chace and kill, they will not eat it. This noisome odour, and the aversion of the cats, most probably gave rise to the notion that the shrew mouse is a venomous animal, and that its bite is hurtful, particularly to horses; but the truth is, that it is neither venomous nor able to bite, for its mouth is not capable of sufficient extension to take in the double thickness of another animal's skin, which is absolutely necessary in order to bite. Besides, the distemper among horses, which is vulgarly attributed to the shrew mouse, is a swelling proceeding from an internal cause, and therefore can have no connexion with the bite, or the puncture of this little animal. The shrew mouse, especially in winter, fixes its residence in stables, hay-lofts, or barns; it feeds on grain, insects, and putrid flesh. It also resides in woods and fields, where it lives on grain; it sometimes conceals itself under moss, leaves, the trunks of trees, and sometimes in holes abandoned by moles, or in holes of a smaller size, which it digs for itself, with its claws and snout. The shrew produces, it is said, as many young at a time as the common mouse, but not so frequently. Its cry is more sharp, but it is not near so nimble, and as it sees imperfectly, and runs slowly, there is very little difficulty in taking it. Their usual colour is brown mixed with red, though some are ash-coloured, and all of them are white under the belly. They are very common throughout Europe, but do not seem to exist in America. The animal of Brasil, which Marcgrave mentions as the shrew mouse, and describes with three black stripes upon the back, is larger, and appears to be of a different species. THE WATER SHREW MOUSE. This animal, though a native of these climates, was unknown to any of our naturalists, until M. Daubenton first discovered and described it in the Memoires de l'Academie, in 1756. To the former animal we have only to add, that this is taken near the source of fountains, as the sun rises and sets; that in the day it remains concealed in the clefts of rocks, or in holes at the edges of rivulets; that it brings forth in spring, and has generally nine young ones at a time.
