DISEASES OF THE RESPIRATORY ORGANS. S07 



there is dullness on tapping with the finger, bronchial respiration 

 is heard. The animal continues to lie on the belly or support him- 

 self with his fore-legs. In this degree of the disease the prognosis 

 is always uncertain. The animal often sinks rapidly and dies of 

 asphyxia. We now begin a still more stimulant treatment, using 

 the veratrum as before but in larger doses and adding tincture of 

 aconite root, one drop to each dose {\^b). Enemas of brandy, 

 and beef tea must be given, as well as by the mouth, in order to 

 sustain the sufferer. We also give the turpentine and ^^% mixture 

 by the mouth (54), and bark tea and the fresh solution of acetate 

 of ammonia (No. 55), quinine, leptandrin and powdered iron too, 

 in large doses with sub-carbonate of bismuth if there is vomiting. 

 Small doses of quinine do not answer the purpose, exerting an in- 

 fluence upon the heart that we'do not desire. A bhster too will be 

 of value applied over the affected side, though the liniment will per- 

 haps do. If there is delirium, look out for trouble, for the animal 

 will not only be difficult to manage, but the disease may be looked 

 upon as fatal. Now no opium must be given, but full doses of 

 hyoscyamus, cannabis indica, and similar sedatives may be used 

 instead. 



When resolution begins to take place, we hear afresh the small 

 crepitation, at first alone, then mixed with the natural respiratory 

 murmur, which in its turn becomes alone audible. The discharges 

 return to their catarrhal character. In the meantime the dysp- 

 noea and fever diminish, and then cease-entirely. 



It would doubtless be very interesting to determine, in a given 

 case, whether the lung of the sufferer was in the second or third 

 stage of inflammation. But there are no certain means for mak- 

 ing this distinction. We may guess that such is the fact when the 

 discharges assume a prune juice color. The appearance of diar- 

 rhoea is not to be depended on, as it appears frequently, with the 

 inception of the second stage. However, the discharges will not 

 help us much ; for sometimes the lung may be in a state of suppura- 

 tion on the fifth day ; and again it may be found in a state of red 

 hepitization as late as the twentieth or twenty-second day. 



When pneumonia passes into gangrene, which is much oft- 

 ener the case with dogs than is supposed, the discharges become 

 of a greenish, or reddish, or dirty grey color, and exhale a pecu-
