Spedjio Contagiotis Diseases. \ 41 



pink vessels, a whitish discharge often takes place from the 

 nose, and with it an increased repulsiveness and often dis- 

 tinct f oetor of the breath ; if tlie bowels are involved scour- 

 ing is common, and if the bones, swelling and lameness in- 

 crease. Exhaustion with profuse perspiration and labored 

 breathing occur on the slightest exertion, the appetite fails, 

 tympany follows each meal, and the milk is at once poorer 

 and lessened in quantity. The cough increases, becomes 

 rattling, the discharge profuse, fetid, mixed with cheesy- 

 like or chalky particles, crepitating, wheezing, gurgling 

 and other abnonnal noises are heard in the chest, and 

 percussion shows dulness in particular parts with wincing. 

 All of the symptoms become steadily aggravated, and the 

 animal usually perishes from the difficulty of respiration 

 or the profuse fetid diarrhoea. In cases affecting the 

 bones, the patient may be unable to stand, and the bony 

 prominences may make their waj' through the skin or 

 even crumble under the pressure thrown upon them. If 

 the tubercle is deposited in liver, pancreas, or kidneys, there 

 are symptoms of disease of these respective organs. 



Recoveries sometimes ensue in connection with healing of 

 vomicae or calcification of the tubercles in strong subjects, 

 but more frequently the disease progresses to a fatal issue. 



Treatment. This is unsatisfactory as being rarely suc- 

 cessful, and even then in preserving an animal which is dan- 

 gerous as a breeder for producing a progeny predisposed to 

 this disease, and for slaughter and dairy purposes as possi- 

 bly conveying the malady to man. 



The most promising course is to secure dry, pure air, 

 sunshine, a genial temperature, lich and easily digestible 

 food, containing abundance of fat (linseed, corn, beans, 

 peas, potatoes), a course of tonics (linseed or cod-liver oil 

 in small doses, sulphate of iron, hypophosphite of iron, 

 quinia, gentian, etc.), and antiseptics (fumes of burning 

 sulphur, bisulphite of soda, sulpho-carbplate of iron, §tc.).
