TREATISE 0.\ MILCH COWS. 



Fourth Order. — These Cows, while at the hight of their flow, yield ten 

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



The escutcheon is yet more reduced ui size. The points A A lower down aud 

 nearer together. The lines are more curved at the points J J, and the distance 

 from these points to N is much less. Below A, on the right side, there is a fail- 

 ure of the upward growing hair, marked P. 



Fifth Order. — These Cows, while at the hight of their flow, yield eight litres 

 a day, ?ftid continue to give milk until they are four months gone with calf. 



The escutcheon goes on contracting in size. The points A A, heing now on 

 the inner surface of the thighs, are no longer so apparent. The upper extremity 

 N is much farther below the vulva. At both points A A there is a failure of the 

 ascending hair (P P), where its place is occupied by descending hair, running in- 

 to the escutcheon. These marks are about five inches deep, by four in width. 



Below the vulva there is a small streak of ascending hair (E), about an inch 

 and a quarter long, by less than half an inch wide. 



Sixth Order. — These Cows, while at the hight of their flow, yield six litres 

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



The escutcheon is on a still more contracted scale than in the preceding Order. 

 Near the vulva, to the left, there is a streak of ascending hair (F), which bristles 

 up. It is nearly five inches long, by about one and a half in width. 



Seventh Order. — These Cows, while at the hight of their flow, yield four 

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



The escutcheon is smaller and lower down than in the preceding Order. On 

 the right and left of the vulva are two streaks of ascending hair, which bristles 

 up. The one on the left (F) is somewhat longer than that found in the Sixth Or- 

 der ; the one on the right (C) is about four inches long, by an inch and a half in 

 width. Below the point A, on the right hand, there is a failure of the ascending 

 hair (P). 



Eighth Order. — These Cows, while at the hight of their flow, yield tuo 

 litres a day, and continue to give milk until they have conceived anew. 



The escutcheon is hid away between the thighs ; the points A A scarcely per- 

 ceptible. The streaks of bristling hair (C C) on the right and left of the vulva 

 are of the kind indicative of the degeneracy and bad quality of the Cow. 



COW OF MEDIUM HIGHT. 



FmsT Order. — These Cows, while at the hight of their flow, yield fourteen 

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

 milk until they are seven months gone with calf 



Third Order. — These Cows yield ten litres a day, and continue to give milk

Fourth Order. — These Cows yield eight litres a day, and continue to give milk

Fifth Order. — These Cows yield six litres a day, and contmue to give milk 

 until four months gone with calf 



Sixth Order. — These Cows yield five litres a day, and continue to give milk 

 until three months gone with calf 



Seventh Order. — These Cows yield three litres a day, and continue to give 

 mijk until two months gone with calf.
