cattle, and preeminently the holding the head too high, and 

 pouring the liquid in a steady stream. Cases are on record in 

 which an ear of wheat was found imbedded in a bronchium 

 (Guillaume), and an ear of another graminaceous plant (Blanc). 



Lesions consist in intense broncho-pneumonia, suggesting 

 pulmonary oedema, followed by hepatization or abscess, which 

 may burst into bronchium or pleura. Hence empyema is some- 

 times found with a variable amount of effusion and false mem- 

 branes. Extensive gangrene of the lung may be present, and 

 the generally diffused petechias of septicaemia. 



Symptoms become rapidly developed, frequent paroxysms of 

 coughing, with hurried breathing, fever, and a rapid emaciation. 

 In milder forms the cough and loss of condition may be the 

 principal symptoms. 



Prevention should be sought, as curative treatment is usually 

 fruitless. 



INHALATION BRONCHO-PNEUMONIA IN DOGS. 



Causes. The predisposition comes largely from inflammatory 

 affections of the throat, as in distemper, which interfere with 

 proper sensation and deglutition. The careless giving of drinks 

 at such a time has been charged with half the deaths fCagny), 

 others are attributed to inhalation of dry sulphur (Albrecht), 

 and others to dry jalap (Cadeac). It must be borne in mind 

 that section of the vagus in dogs first showed the production of 

 experimental broncho-pneumonia by the resulting nervous im- 

 perfection, and the interference with nervous control during 

 agony operates in the same way. The congested and swollen 

 tonsils, fauces and pharynx, covered with muco-purulent matter 

 and even scabs and sloughs prove poor sentinels at the vestibule 

 of the lungs, and more or less of the food materials or medica- 

 ments enter through the larynx. Worse than all, in ulcerous 

 stomatitis the tenacious or inspissated exudate and sloughs of 

 the gums and mucosa, swarming with bacteria are liable to in- 

 halation in the same way and form irritating foreign bodies of the 

 worst kind, because of their dangerous microorganisms already 

 accustomed to life in the tissues. 



Other foreign bodies are inhaled by dogs which are breathing 

 hard under violent exertion (dust of highways, or railway
