    FAIRS OF MOLE. In the larger hairs of the Mole, which we will now look at, the bark is very thin; and though the surface is marked with sinuous lines, these do not project into teeth. The pith here again forms the greater portion of the hair, the cells of which it is composed being placed in single series, which, for the most part, extend all across the body of the hair, though they are somewhat irre- gular both in size and shape. They are rather flattened, and appear perfectly black (that is, opaque) by transmitted light, their surfaces absorbing all the rays of light. The small hairs of the same animal, how- ever, are very different in form ; they are flattened, so as to appear twice as broad in one aspect as in another at right angles to it; and, what is curious, the scales of the bark project into strongly marked imbrications on one side, and are scarcely per- ceptible on the other. Here, as in the larger hairs, there is a single row of oval transverse cells, perfectly opaque. The hair of many of the |( smallerMammalia shows con- |) siderable diversity of form, according to the part which \\ we HAIR OF SABLE. select for observation. Thus, if we take a long hair out of this Sable tippet, and examine it near the base, we see (a) that it is very
