CATTLE. 



When an external lesion, as a blow, &c., has occasioned extenial 

 swelling and inflammation of the neck, in consequence of which an 

 angina has supervened, we are to give some doses of aconitum, then 

 arnica, which are sufficient in many instances, unless the inflamma- 

 tion has made too much progress. If, after the inflammatory symp- 

 toms have been removed, there remain a swelling in the neck, we 

 should have recourse to baryta carhonica, and when that is not suffi- 

 cient, to hepar sulphuris. 



BRONCHITIS. 



When catarrh begins to spread, and to involve the lower and more 

 important air-passages, it attacks the bronchial tubes oftener than 

 any other portion of the respiratory apparatus, and is inflammation 

 of the lower and minuter air-passages. It used to be called inflam- 

 mation of the hint^s in cattle, and is so considered by the majoi-ity of 

 farmers and cow-leeches ; but since the improvement of veterinary 

 science, this distinction, one of some moment, has been established. 

 Bronchitis, however, is seldom pure ; it is the prevailing disease, but 

 it is complicated with slighter inflammation of the neighboring sub- 

 stance of the lungs. Bronchitis is rarely sudden in its attack. It is pre- 

 ceded, and generally for a long time, by cough, which becomes more 

 and more frequent and painful, and husky and wheezing. 



Here, then, is another motive for attention to the hoose of cattle. 

 Simple catarrh may do little harm ; but the inflammatory affection 

 will gradually involve other and more important membranes, inflam- 

 mation of which is generally fatal. Bronchitis is the intermediate 

 step between catarrh and consumption, and it unfortunately is tha< 

 step which, if once taken, the other must follow. We may, th^re 

 fore, except when the disease assumes an epidemic character, (whicl 

 it not unfrequently dors, and particularly in young cattle,) attribute 

 it to the neglect or mismanagement of the herdsman or the owner. 



The existence of bronchitis may usually be detected by a gradua' 

 change of the countenance ; a sunken, anxious, haggard look ; i 

 rapid and laborious breathing, attributable, at first glance, to some 

 thing more than mere catarrh, however severe that may occasionalh 

 be ; a cough, painful to a very great degree, and against the fuL 

 action of which the animal strives as much as he is able, so that it ii 

 not full and perfect, but hn^kr/ and wheezing. There is a very con- 

 siderable disinclination to mo\e, which is easily accounted for ; foi 

 inflammation of the bronchial membrane is accompanied by thicken- 

 ing of it, and by the secretion of a quantity of viscid mucus, so tha\ 

 the passages are, to a considerable degree, obstructed. This gives a 

 consciousness of the danger of suffocation, and occasionally the 

 disease tenninates in suffocation. The slightest motion aggravates 

 the cough ; and motion of a sudden kind sadly oppresses and terri- 

 fies the animal. The breath is hot. The seat of inflammation being
