PLEUEO-PNEUMOKIA. 611 



Fifthly, All the animals, with the exception of milk cows, 

 should be fed judiciously, and receive in their food from two 

 drachms to half an ounce of sulphate of iron daily. Suppose 

 there are ten oxen feeding in stalls, a dozen calves in the 

 strawyard, a dozen two-year-olds in a field, I should pre- 

 scribe as follows. For the ten oxen,

Mix. Make four dozen such powders. Mix a powder 

 thoroughly with two pecks and a half of bran and bruised 

 oats or other feeding material. This is sufficient for one day 

 for the ten oxen, giving each animal the fourth of a peck of 

 the mixture. The treatment must be continued till the 

 forty-eight powders are used, that is to say, forty-eight days. 



For the twelve two-year-olds, if not stall-fed, I would mix 

 a similar powder daily in any food they would take, or if 

 being fed on turnips, would cause the latter to be wetted 

 daily, and sprinkled over with the powder. For the calves, I 

 should halve the above powders. 



Sixthly, The milk cows must be simply watched, and the 

 attendants on the animals must be made to announce when- 

 ever the slightest symptoms of ill health appear in any case, 

 and the affected one must be instantly removed. 



Concerning dairy stock I have now to say, the iron treat- 

 ment cannot be adopted, segregation is alone at our disposal. 

 Farmers and dairymen should be most careful with their 

 purchases, and it is usually found that the early removal of 

 any animal showing signs of disease has a marked effect in 

 diminishing the number of cases. Cows that are nearly off 

 their milk should be dried and receive tonics like other 

 cattle, and in some instances it is desirable to dry the whole, 

 feed them up, and sell to the butcher. Clearing out a
