no case did it extend beyond the circumference of the valves ; the 

 lining membrane of the heart always remained intact. 



BRONCHIAL TUBES. 



Swine are very susceptible of bronchitis, and also liable to worms 

 in the bronchia, both of which affections manifest themselves under 

 the form of cough, inappetency, and loss of flesh. The former may 

 be subdued by bleeding and cooling medicines, as sulphur, cream of 

 tartar, or pulv. antimonialis : the latter almost invariably cause the 

 death of the animal from the irritation they create and the iiiflam 

 mation which is thus set up.

INFLAMMATION OF THE LUNGS. 



This disease is perhaps more generally known under the term of 

 rising of the lights ; it is one of the most prevalent and too often the 

 most fatal of all the maladies that infest the sty. It has been sup- 

 posed by some, persons to be contagious, by others to be hereditary, 

 but there does not appear to be any actual foundation for either of 

 these opinions. By far the most probable supposition is, that it arises 

 from some atmospheric influences or agencies which create a ten- 

 dency to pulmonary affections, and these, acting upon a system 

 heated and predisposed to disease by the mode of feeding adopted 

 in most piggeries, give a serious and inflammatory character to that 

 which would otherwise be merely a simple attack of catarrh ; or it 

 may arise from some irritating influence in the food itself, or from 

 damp, ill- ventilated styes : whatever be its cause, it generally runs 

 through the whole piggery when it does make its appearance. The 

 prominent indications of disease are loss of appetite, incessant and 

 distressing cough, and heaving at the flanks. 



As soon as the first symptoms are perceived, the animal should 

 be bled ; the palate perhaps will be the best place in this case to 

 take blood from ; purgatives must then be given, but cautiously ; 

 Epsom salts and sulphur will be the best, administered in a dose of 

 from two to four drachms of each, according to the size of the ani- 

 mal. To these may succeed sedative medicines : digitalis, two 

 grains, pulv. antimonialis, six grains, nitre, half a drachm, forms a 

 very efficient and soothing medicament for moderate-sized pigs, and 

 will often produce very satisfactory effects ; cleanliness, warmth, and 

 wholesome, cooling, nutritious food, are likewise valuable aids in 

 combating this disease. But whatever measures are taken, they 

 must be prompt; for inflammation of the lungs runs its course 

 with rapidity and intensity, and, while we pause to consider what *s 

 best to be done, saps the vital energies of the patient.
