CHROXIC INTERSTITIAL PNEUMONIA 145 



results with Priessnitz's compress and from the remedies recommended 

 under the treatment for bronchitis. The good effects of moist, warm 

 compresses can be much increased by sharp friction with a small cjuan- 

 tity of mustard oil to the sides but it must be applied only in young, 

 strong, healthy animals. The best method of application is to make a 

 liniment of 3 parts of oleum sinapis aethereum in 45 parts of olive oil and 

 divide it into 2 parts and apply one-half to each side of the chest then 

 wind a dry bandage around the chest walls and ten to twelve hours later 

 apply Priessnitz's compress. Narcotics are to be given when the cough 

 is constant and distressing. Where there is much debility stimulants 

 such as wine or ether are indicated and the animal should be given small, 

 often-repeated quantities of chopped meat, juice of meat pressed from 

 raw beef, broth, milk, and the peptone preparations. 



Some good is to be derived from inhalations in this disease. When 

 the breath is offensive we advise inhalations of benzoin, 4.0 to cup of 

 boiling water. Inhalations of creosote are recommended, but on account 

 of the danger of absorption and irritation of the kidneys 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 oedema of the lung is recognized, it must be regarded as a 

 grave symptom for it is 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. 



Other Diseases of the Lungs. 



Catarrhal pneumonia is the only important disease of the lungs in 

 the dog; the others which are here described are of small importance 

 and rarely seen. 



Congestion of the Lungs, Acute Hyperaemia of the Lungs. — This dis- 

 ease is comparatively rare, generally being observed in the summer, as a 

 result of very severe exercise; for example, in hunting dogs, in warm 

 weather, or animals running after cars, wagons, or bicycles until ex- 

 hausted, or as a result of infiltration of the lung in ascites, or from cold 

 air, gas, great heat or smoke if the animal has been in a burning house 

 or kennel, etc. 



The early acute symptoms are greatly accelerated respiration, 

 mouth open, tongue deep blue to purple and hanging out, animal restless 

 and excited, heart full, bounding, and easily felt through the chest wall, 

 hard full pulse, cyanosed mucous membranes, and if the acute condition 

 continues for any length of time, apoplectic cedema, apoplexy, or
