The first part is represented by itself, in [Figs. 37] and [49]. We shall call the former mammary, and the latter perinean. The former is sometimes large, extending over the milky glands, the thighs, and the legs, as shown in [Figs. 29] to [37]; and sometimes circumscribed, or more or less checked over with tufts of downward-growing hair, as in [Figs. 43] to [52]. It is sometimes terminated towards the upper part of the udder by a horizontal line, straight, as in [Fig. 37], or angular, as in [Fig. 49]; but more frequently it continues without interruption over the perineum, and constitutes the perinean part.

This presents a large band, [Fig. 30], straight, as in [Fig. 43], and bounded on the sides by two parallel lines, as seen in the same figures, or by curved lines, as in [Fig. 34]. It sometimes rises scarcely a fourth part up the perineum, as in [Fig. 38]; at others, it reaches or passes beyond that part, forming a straight band, as in [Figs. 35] and [43], or is folded into squares, as in [Figs. 31] and [36], or truncated, [Fig. 38], or terminated by one or several points, [Figs. 32], [33], [41], [50]. In some cows this band extends as far as the base of the vulva, [Figs. 40] and [48]; in others, it embraces more or less of the lower part of the vulva, [Figs. 29], [30], [39], and [47].
