Broncho- Pneumonia from Inhalation. 305 



betoken the advent of pleurisy, or splashing or metallic tinkling 

 the advent of hydro-pneumothorax. 



In case of a foreign body passing from the reticulum ; the line 

 of extensive exudation may sometimes be traceable by the dull- 

 ness on percussion, or by a clucking sound on auscultation, and, 

 as in pleurisy, there is usually a dropsical swelling, pitting on 

 pressure beneath the lateral parts of the sternum or between the 

 ■ first ribs. 



The constitutional symptoms, accelerated pulse, elevated 

 temperature, suppressed secretions, are more or less marked in 

 different cases. Foetid breath and expectoration are to be looked 

 for. 



Diagnosis. From lung plague it is distinguished by the pres- 

 ence of multiple small areas of dullness instead of one large area, 

 by a more frequent and stronger cough, by the presence of foetid 

 breath instead of the heavy mawkish odor of the exhalation, and 

 usually by the rnore moderate fever and the absence of other 

 cases in the herd, or of some evidence of infection. If there is a 

 question of tuberculosis apply the tuberculin test. 



Prevention has been fairly indicated under causes. The protec- 

 tion against inhalation of drenches consists mainly in only 

 slightly elevating the head, leaving the tongue free, and pouring 

 the liquid into the mouth in successive small quantities which are 

 to be swallowed before more is given. Especially is this to be 

 secured in drenching recumbent animals, and above all those suf- 

 fering from milk fever, though the success of the modern treat- 

 ment by udder distension virtually excludes the necessity of 

 giving liquids by the mouth in that disease. 



Treatment In cattle, the issue is rather more hopeful than 

 in horses, but the same general treatment is advisable. Beside 

 the general treatment of the fever and local inflammation, the 

 use of antiseptics (carbolic acid, creolin, lysol, chloro-naphtho- 

 leum) in volatile form, or even as liquid, is especially called for. 

 As in the horse the best agent is solution of peroxide of 

 h-ydrogen.

Causes. This is a common trouble from the administration of 

 liquid medicines, the causes being essentially the same as in
