BASTARD OF THE DEMIJOHN COW. 



When the streaks marked F F are found in the Coav of this Class, of the di- 

 mensions specified in the description of the Bastard of the Czirvehne Cow, they 

 serve here also to detect the Bastard Coav ; and i:er badness in regard to the rapid 

 loss of her milk Avill be in proportion to the size of these streaks. The smaller 

 they are, the less defective Avill she be in this respect. (See Plate IX. Fig. 6.)

 rior Orders of the preceding Classes. The udder delicate, covered Avith short, 

 fine hair. The escutcheon begins as in the foregoing Classes ; and, rising from 

 just above the hock joint, on the inner surface of the thighs, spreads outward to 

 the points A A. (See Plate VI. Order 1.) Above those points it represents a 

 square. A right line runs across to the points J J, distant from each other from 

 five to six inches. Thence the figure is bounded by two right lines, which meet 

 in an acute angle at the point E, distant about tAvo inches from the vuh'a. Above 

 that, to the left, the figure of a square is formed by tAA'o streaks of hair, E B an^i 

 B C (the point C being at the orifice of the vagina) ; the former of which is about 

 four inches long, by an inch and a quarter Avide, and the latter from five to six
