BRONCHITIS. 



deep, no pain is indicated when the side of the animal is pressed 

 upon, or lightlj struck, and the animal does not gaze anxiously p.t its 

 sides. The most important of all, and marking the fatal progress of 

 the disease, the animal loses flesh rapidly, to a very great extent, and 

 becomes a mere skeleton. 



To young cattle bronchitis is particularly destructive, and the 

 symptoms and accompanying circumstances are very singular. A 

 yearling is often observed to have a cough peculiarly distressing. If 

 bled, and setoned, and physicked, the symptoms will sometimes 

 rapidly abate ; but in most cases remedial measures are applied in 

 vain. The cough continues as distressing as ever. The intermissions 

 are short, and the paroxysms exceedingly violent. The beast is off 

 his feed, hide-bound, his belly tucked up, his coat staring, his flank 

 heaving, and it is. painful to hear him cough. This occurs principally 

 on low, marshy woody lands. 



The animal at length dies, and the whole of the brorchial passages 

 are found to be completely choked up with worms. They are of the 

 strongylus species, and mostly the Jilaria. Many of them are also 

 found in the windpipe ; and the mucous membrane both of the 

 windpipe and the bronchial passage presents an appearance of the 

 intensest inflammation. 



Worms are oftenest found in an injurious quantity in a moist state 

 of the atmosphere, or in moist situations, and especially in those 

 which abundantly produce the vegetables and grasses peculiar to 

 such a locality ; and also in young subjects, and in those whose con- 

 stitution is somewhat enfeebled. 



Bronchitis, when not attended with all the violent symptoms that 

 characterize the existence of worms in young cattle, should be treat- 

 ed like other inflammatory complaints." Bleeding will, as usual, be 

 the first remedy, and it should be carried to the extent which the 

 pulse will allow ; in general, however, the ox will not, in this com- 

 plaint, bear the loss of so much blood as in other chest aftections. 

 To this should follow physic, and the sedative medicines already 

 recommended, with mashes, <fec. 



In some cases a favorable termination of the disease has been pro- 

 duced ; but in the bronchitis with worms there are exceedingly few 

 cases of successful treatment. jSTo drug can be brought to bear upon 

 these worms directly ; for no fluid at all can pass into these tubes. 

 Diluted chlorine gas might be inhaled. It might be breathed more 

 readily, if an artificial opening were made into the larynx. Other 

 symptoms of bronchitis, and particulai-ly the feeling of suff'ocation, 

 might also be reheved or removed by this. 



The animal would, probably, be much annoyed by such inhala- 

 tion ; he might cough for a while with even greater violence ; but 

 the woi-ms dying, or their hold being loosened, they might be ex- 

 pelled through the natui-al or artificial opening by the very urgency
