INFLUENZA. 



35'r 



If there be abdominal complications, tlie colicky pains are to 

 be relieved by warm fomentations to the belly, and small doses 

 of opium, the bowels being regulated by oil. But even here no 

 very decided and heroic steps are to be taken to relieve symp- 

 toms, it being always kept in view that they are the result of 

 a cause which will not expend itself until a certain period, and 

 that mere remedies, although perhaps affording relief at the time, 

 are generally debilitating in their effects, and often tend to 

 cause a fatal termination. 



The sequelc^ of influenza are, hydrops pericardii, hydrothorax, 

 ulceration of the larynx, roaring, and sometimes glanders and 

 farcy. 



MORBID ANATOMY. 



Uncomplicated influenza seldom proves fatal, except in the 

 very old or otherwise debilitated animal ; the most prominent 

 lesions being great congestion of the mucous membrane of the 

 respiratory track, extending even into the minute bronchi, some 

 of which are filled with a muco-purulent discharge; the pul- 

 monary lobules being consequently collapsed. The blood is 

 dark, and is said to contain micrococci. The majority of fatal 

 terminations are caused by the gravity of some local compli- 

 cation, such as pneumonia, bronchitis, &c.

In Manchester it has been found that many dead animals 

 present a dark patch of congestion, with incipient ulceration on 

 tlie mucous membrane of the stomach, as shown above.
