BRONCHITIS IN CATTLE IN JAMAICA.' 8ol 
out what steps you must lake—you must make yourselves 
masters of the history of the case, and be guided by circum¬ 
stances. Let the overtilled cow-houses be enlarged, and the close 
and hot ones better ventilated—let cruel neglect, and exposure, 
and starvation yield to more judicious and humane treatment— 
when cattle are fed on dry meat, let them have sufficient to drink 
two or three times every day - let those that exhibit decided 
symptoms of phthisis be removed from the dairy, not because 
the disease is contagious, but because it is undeniably hereditary : 
in fine, in a case where generally so little can be done in the 
way of cure, let nothing be omitted in the way of prevention. 
THE MORBID APPEARANCES OF BRONCHITIS IN 
CATTLE ON THE ISLAND OF JAMAICA. 
Report of the morbid Appearances on the post-mortem Examina¬ 
tion of a Steer killed for that purpose, and supposed to be 
labouring under a Disease in Jamaica (prevailing among 
cattle only), and there commonly called ‘‘ Cough — 
“ This steer, called Blueman, ten years old, had commenced 
to w’ork in 1826. His first symptoms of disease were discovered 
about two years ago. No remedies were used ; he was turned 
out, and left to nature, changing the pasture occasionally be¬ 
tween the sea-side and mountain climate, and looked after, among 
others in the same disease, with care and attention, choosing for 
them alwavs the best pasturage on the estate. 
Upon dissection, the tongue was found clean, and of its natural 
colour and appearance ; the fine delicate membrane lining the 
trachea or windpipe, especially about the end next the fauces, 
was studded, and thickly covered, with a disorganized deposition, 
to the eye like hydatids, but fixed to the membrane itself; and 
not hanging down like the grape-bunch, and of various sizes, 
resembling herring-roe or fish-spawn. On being cut into, a sub¬ 
stance turned out of a gritty calculous description, so firmly 
connected as scarcely to be separated; in some comparison like 
tubercles that form in the substance of the luno-s or liver in the 
human subject, after long-continued disease, but of much larger 
proportion. This substance w^as traced partially along the canal 
of the whole tube, extending to the bronchia, and embedded 
itself eventually in the substance of the luno;s, where alone it 
appeared accompanied by purulent matter, or pus of a yellow 
thick consistence. It was found in vaiious parts of the lungs, 
in its substance, also adhering to its pleura externally, and the 
adjacent parts, as the pleura costalis, where some degree of
