326 BKONCHITIS PLEUBIST. 



the windpipe, so that air can not escape through it, and then 

 between such compression and the body of the liings, in a 

 closely fitting orifice, insert a goose quill or other tube, and 

 continue to blow until the lungs are inflated so far as they can 

 be. As they inflate they will become lighter colored, and 

 plainly manifest their cellular structure. If any portions of 

 them can not be inflated, and retain their dark, liver-like 

 consistency and color, they exhibit hepatization — the result 

 of high inflammatory action — and a state utterly incompati- 

 ble, in the living animal, with the discharge of the natural 

 functions of the lungs. 



With the treatment of pneumonia, I have but little 

 personal experience. In the first or inflammatory stages of 

 the disease, bleeding and aperients are clearly called for. Mr. 

 Spooner recommends " early and copious bleeding, repeated, 

 if necessary, in a few hours — this followed by aperient 

 medicines, such as two ounces of Epsom salts, which may be 

 repeated in smaller doses if the bowels are not sufficiently 

 relaxed. The following sedative may also be given with 

 gruel twice a day : — nitrate of potash, one drachm ; digitalis 

 powdered, one scruple ; tai'tarized antimony, one scruple." 



The few cases I have seen have been of a sub-acute charac- 

 ter, and would not bear treatment so decided. Mr. Youatt 

 remarks : — " Depletion may be of inestimable value during the 

 continuance — the short continuance — of the febrile state; but 

 excitation like this will soon be followed by corresponding 

 exhaustion, and then the bleeding and the purging would be 

 murderous expedients, and gentian, ginger, and the spirit of 

 nitrous ether will afford the only hope of cure." 



Bronchitis. — It would be difficult to suppose that where 

 sheep are subject to pneumonia they would not also be subject 

 to bronchitis — which is an inflammation of the mucous mem- 

 brane which lines the bronchial tubes — the air-passages of the 

 lungs. I have seen no cases, however, which I have been 

 able to identify as bronchitis, and have examined no subjects, 

 after death, which exhibited its characteristic lesions. Its 

 symptoms are those of an ordinary cold, but attended with 

 moi'e fever and a tenderness of the throat and belly when 

 pressed upon. Treatment : Administer salt in doses from 1-J 

 to 2 oz., with 6 or 8 oz. of lime-water, given in some other 

 part of the day. This is Mr. Youatt's prescription. 



Plbueitis ok Pleurisy. — I have seen no instance of this 

 disease. Mr. Spooner says of it : — " This disease consists of
