272 SPECIFIC DISEASES. 



To administer this shallow troughs are made with fences at 

 the side, and the sheep compelled to walk through them, the 

 medicinal agents being mixed with water in the troughs. For 

 this the following will be useful: 



Take. Sulphate of zinc 2 lbs. 



Acetate of lead 2^- lbs. 



Carbolic acid crystals 8 ounces 



Water 10 gallons 



Mix thoroughly, pour into trough and compel the affected 

 animals to walk through it once or twice daily, and care should 

 be taken that lame sheep immerse each foot, as they are apt to 

 hop throvigh on three legs. This mixture must be stirred thor- 

 oughly before passing sheep through it. 



"Cubcrculoaie — Consumption. 



This is a rare affection of sheep, and while tables 

 mesenterica has frequently been reported as present in post- 

 mortem, we must believe that it has been confounded with 

 nodular disease of the intestines, due to the oesophagostoma 

 Columbianum, a very prevalent condition, which is described in 

 the chapter on internal parasites. 



Walley, in his work, "The Four Bovine Scourges," writing 

 concerning tubercle, says as follows: 



"Species of animal: The bovine tribe is pre-eminently 

 disposed, equally so indeed with man. Next in order comes the 

 common rabbit, which animals in some districts are almost anni- 

 hilated by the disease; the pig is very prone to tubercle, as are 

 also poultry, our feathered household pets, and under certain cir- 

 cumstances, game birds. I have even seen it in the rook, though 

 it is curious that the palmapedes are exempt from it. Tubercle 

 is rarely seen in the sheep, cat or dog."
