MEDICAL TREATMENT OF DOMESTIC ANIMALS. 49I 



" on the approach of the fly. Others smear their noses with tar, 

 " or cause them to smear themselves, by sprinkling their salt over 

 " tar. Those fish oils which repel the attacks of flies might be 

 " resorted to. Blacklock suggested the dislodgment of the larvas 

 " from the head by blowing tobacco smoke up the nostrils — as it 

 " is said to he effectual. It is blown from the tail of a pipe, the 

 " bowl being covered with cloth. Tobacco-water is sometimes 

 " injected with a syringe for the same purpose. The last should

" Catarrh. — Catarrh is an inflammation of the mucous mem- 

 '' brane which lines the nasal passages — and it sometimes extends 

 " to the larynx and pharynx. In the first instance — where the 

 " lining of the nasal passages is alone and not very violently 

 " affected — it is merely accompanied by an increased discharge of 

 " mucus, and is rarely attend^ed with much danger. In this form 

 " it is usually termed snuffles, and high-bred English mutton 

 " sheep, in this country, are apt to manifest more or less of it, 

 " after every sudden change of weather. When the inflammation 

 " extends to the mucous lining of the larynx and pharynx, some 

 " degree of fever usually supprvenes, accompanied bv cough, and 

 "some loss of appetite. At this point the English veterinarians 

 " usually recommend bleeding and purging. Catarrh rarely attacks 

 " the American fine-wooled sheep with sufficient violence, in sum- 

 " mer, to require the exhibition of remedies. I early found that 

 " depletion, in catarrh, in our severe winter months, rapidly pro- 

 " duced that fatal prostration from which it is next to impossible 

 " to recover the sheep — entirely impossible without bestowing an 

 " amount of time and care on it costing far more than the price of 

 *' anv ordinary sheep. 



" The best course is to prevent the disease by judicious pre- 

 " cautions. With that amount of attention which every prudent 

 " flock-master should bestow on his sheep, the hardy American 

 " merino is little subject to it. Good, comfortable, but well- 

 " ventilated shelters, constantly accessible to the sheep in winter,
