around the chest-walls, and ten to twelve hours later apply Priess- 

 nitz's compress. 



In cases where there is great accumulations of mucus it is 

 advisable to give the animal an emetic (apomorphia is the best). 

 Xarcotics are to be given when the cough is constant and distressing. 

 "Where there is much debility stimulants are indicated, such as 

 wine, ether, and give the animal small, often-repeated quantities 

 •of chopped meat, broth, milk, and the peptone preparations. 



Very little good is to be derived from inhalations in this disease. 

 AVhen the breath is offensive we advise inhalations of turpentine 

 or a 1 to 50 solution of creolin. Inhalations of carbolic acid are 

 recommended, but on account of the danger of poisoning by that 

 drug they are to be used with extreme caution. In septic fever, 

 after the appearance of gangrene of the lungs, give subcutaneous 

 injections of ether or camphor. 



When cedema of the lung is recognized, it must be regarded as 

 a grave symptom and generally fatal. We must, therefore, take 

 very energetic measures — active stimulants, such as mustard oil, 

 to the sides, and also injections of ether or camphor subcutaneously. 

 Bleeding and the use of cardiac stimulants, such as digitalis or 

 •caffeine, are useless. 



Catarrhal pneumonia is the only grave important disease of the 

 lungs ill the dog; the others are of small importance. 



Croupal inflamuiation of the lungs, as we understand it, is a 

 jfirm, hemorrhagic exudation in the alveoli of the lungs and small 

 bronchia. This is very rare in the dog. The author has never 

 seen a case of true lobar pneumonia, but has seen a few cases of 

 croupal lobular pneumonia, the course of which is very similar to 

 •catarrhal pneumonia in all its symptoms, the difference only being 

 detected on post-mortem. Roll makes the statement that croupous 

 inflammation of the lungs is common in the dog, but he probably 

 meant lobular pneumonia. 



Anthrakosis pulmonum (blackening of the lungs) is quite 

 common in the dog, but it has no pathological significance. 



Emphysema of the lungs is not such an important disease in 

 the dog as it is in man and the horse. That form of emphysema 

 which appears in bronchitis and pneumonia, characterized by an 

 extreme distention of the alveoli, has been mentioned under 

 these diseases. If the irritation is constant, the disease becomes
