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 some- what irregular both in size and shape. They are rather flattened, and appear per- fectly black (that is, opaque) by transmitted light, their sur- faces absorbing all the rays of light. The small hairs of the same animal, however, 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 imbrica- tions on one side, and are scarcely perceptible 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 smaller Mammalia shows considerable diversity of form, according to the part which we select for observ- ation. 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 slender, a transparent, and colour- less, covered with strongly- marked imbrications, which are not obtuse teeth, but.
