THE DISEASES OP CATTLE. 365 



would indicate the least deviation from health ; and the only 

 trouble was, the milk did not yield butter. I ordered a small 

 quantity of milk to be drawn from each cow, and, on inspect- 

 ing it, it appeared to have a light blue tinge, resembling 

 milk when artificially watered. On letting it stand for a short 

 time, there appeared to be a deficiency of the oleaginous or 

 butter-making qualities. The only way I could account for 

 this peculiar condition of the milk was, that it arose in con- 

 sequence of faulty alimentation. I therefore prescribed a 

 change of diet, from hay, meal, and turnips, to grass and oat- 

 meal. Next day, I furnished the owner a package of medicine 

 composed of the following agents : — 



Powdered Poplar Bark, 6 ounces. 



" Phosphate of Lime 6 ounces. 



" Ginger, 2 ounces. Mix. 



A tablespoonful of this mixture was given to each cow in 

 the food. By the time it was all used, there was no farther 

 trouble. It is probable that these animals might have re- 

 covered merely through change of diet, without any medicine ; 

 yet as medicine of the above kind is always favorable to health, 

 I do not hesitate to recommend it. 



I find in the London Veterinarian a brief translation of a 

 veiy singular occurrence, which may, perhaps, prove of some 

 value to some of my readers. 



" A letter from a farmer states that he had fourteen cows in 

 full milk, from which he obtained very little butter, and that 

 of a bad quality. Guided by the statements of M. Deneu- 

 bourg, which had appeared in the Annates Veterinaires, he 

 had separately tested the milk of his cows, and found that the 

 bad quality of it was owing to one cow only, and that the milk 

 of the others yielded good and abundant butter. It was there- 

 fore clearly established that the loss he had so long sustained 

 was to be atti-ibuted to this cow only. He at once adminis- 

 tered the remedy recommended by M. Deneubourg, which 

 effected a speedy cure."
