TREATISE ON MILCH COWS. 73 



CLASS V. 



Coto. 



Tills nacre indicates the shape of the escutcheon of this class. It may strike 

 the reader as queer ; but it is significant, and serves to recall the figure of the 

 characteristic mark of the Class, which very much resembles the outline of a dcm 

 ijohn. If my discovery is a useful one, habit will soon accustom people to this 

 name, as well as to the others of my Eight Classes ; and to those who may feel 

 disposed to find fault with them, 1 will say, what matters it to you ? the name is 

 as nothing, the importance is altogether in the thing. 



HIGH COW, 



FIRST ORDER. Cows of this Order and Size, while at the hight of their flow, 

 yield sixteen litres a day, and continue to give milk until they are eight months 

 gone with calf. 



The skin within the escutcheon has the same yellowish color as in the higher 

 Orders of the preceding Classes. The udder is delicate, and covered with fine, 

 downy hair. The escutcheon, consisting of a growth of ascending hair, begins 

 between the four teats, and on the inner side of the legs, above the hock joint , 

 as it extends upward it spreads upon the outer surface of the thighs to the points 

 A A. (Plate V. Fig. 1.) From these points, the figure is bounded by right lines, 

 to the points J J, which are distant from each other from five to six inches. From 

 these points, the upward growing hair rises to the line N, where it is from two 

 and a half to three and a quarter inches in width. This line is directly below 

 the vulva, and distant from it about four inches. The wider the figure is at this 

 place, and the nearer it approaches to the vulva, the better the Cow. 



Above the hind teats are two ovals (E E), formed by descending hair, about 

 four inches long, by nearly three inches in width. On the right and left of the 

 vulva are two streaks of ascending hair (0 0), nearly two and a half inches long, 

 by less than half an inch in widih. The hair within these streaks is fine and 

 short, and very distinct from the dascending hair that surrounds them. 



SECOND ORD.ER. These Cows yield, while at the hight of their flow, four 

 teen litres a day, and continue to give milk until they are seven months gone with 

 calf. 



The escutcheon differs from that of the First Order in being on a smaller scale. 

 Above the teats there is but one oval (E) to the right, formed by descending 

 hair. Of the two streaks of ascending hair (0 0) alongside of the vulva, the 

 one to the left is of the same dimensions as in the First Order ; but the one to 

 the right, although of the same width, is of but half the length. 



THIRD ORDER. These Cows, while at the hight of their flow, yield twelve 

 litres a day, and continue to give milk until they are six months gone with calf. 



The escutcheon, preserving its general shape, is yet more contracted. At the 

 points A A, it is more rounded off, and no longer spreads on the outer surface of 

 f he thighs. Above the points J J, it is narrower ; and it stops short at N consid 

 erably lower down beneath the vulva. There is but one of the streaKS (O) of 

 ascending hair, which is to the left of the vulva, and about an inch ai.a a half 

 long, by two-fifths of an inch in width.
