 serves to reveal its true nature. Its cause being usually 

 incurable, it terminates fatally in the majority of cases. 

 Treatment must be altogether directed to the disease of 

 the heart. 



APOPLEXY OF THE LUNG. 



In the lov^er animals extravasation of blood into the 

 substance of the lung is usually the result of profound al- 

 terations in that liquid as in Malignant Anthrax, Purpura 

 Hcemorrhagica, Typhoid Fever or Intestinal Fever. A por- 

 tion of the lung tissue gives way and the blood escaping 

 raises the membrane covering it (pleura) from a half to 

 three inches above the natural level. The extravasation 

 lias the appearance of a fine jeUy and often preserves the 

 shape of the pulmonary lobules — a cone with the apex 

 turned in. Being usually a complication of another dis- 

 ease, treatment must be directed to that rather than the 

 local lesion. 



PliEUEODYOTA. 



This is a term applied to rheumatism of the muscles be-

 risy. It may be distinguished by the coexistence of rheu- 

 matism in other parts and by the comparative absence of fe- 

 ver, coiigh, rubbing sounds and effusion. Treat it Hke 

 other forms of rheumatism. 



ASTHMA IN DOGS. 



A spasmodical affection of the circular muscular fibres 

 of the bronchial tubes, occurring in paroxysms with irreg- 

 ular intervals and associated with corpulence and disordered 

 digestion, distended or ruptured air-ceUs, mucous dis- 

 charges from the air-passages and dilatation of the right 

 side of the heart. 



Causes. Usually in pet dogs pampered with highly sea- 

 soned articles of food, in excessive quantity, and deprived
