352 BRONCHITIS IN CATTLE IN JAMAICA. 
vascularity was evident. In traversing the windpipe, a small 
worm was discovered, like the end of a thread, or the shape of 
ascarides; but whether the effect of accident or connected with 
the disease we could not ascertain, being the only one found. 
** The liver was also diseased, but seemed to have put on that 
action at a much later period than the parts already described. 
Tubercles containing the same gritty substance were detected in 
different parts of the organ, under the peritoneal covering, and 
not upon the surface, as on the pleura. On cutting into the 
substance of the liver, it was found to contain circumscribed 
cells of the same secretion all through.’^ 
In another animal (a heifer in the last stage of disease), killed 
the same day, the morbid appearance was not found in the wind¬ 
pipe, nor any signs of its having existed there ; but about the 
bifurcation of the windpipe, and commencement of the bronchia, 
at its junction with the lungs, the diseased appearance was ac¬ 
cumulated in a much greater degree than in the steer; and in 
the liver was found a number of living insects, like a small 
flounder, having a mouth or proboscis projecting outward, and 
something of the appearance of an eye on one side, the other being 
regular and flat. On being examined by a magnifying glass, 
they seemed to have the power of motion when discovered, and 
resembled much the rot in sheep at home, in low marshy situa¬ 
tions (if I recollect that disease) : however, I mean a malady of 
that nature, very prevalent and fatal in some parts of England, 
where animalculse are found floating in the liver like these. It 
would appear, as the gritty secretions are deposited in the sub¬ 
stance of the lungs, that the surrounding parts put on a diseased 
action, and the organ itself, and even the air-cells, became de¬ 
generated, and formed a mass of corruption, sui generis.'^ 
A gentleman called on us five or six months ago, and told us 
that his plantation was, in a manner, devastated by a disease 
which commenced with cough, and afterwards assumed many of 
’ the characters of phthisis, and for which no remedy had been 
found. He described the cough to be as urgent and painful as 
the cough of bronchitis among our cattle. We gave him certain 
directions, and recommended the use of the common fever medi¬ 
cine, but said, that on any future consultation it would be more 
satisfactory if he could procure from his agent an account of the 
post-mortem appearances, on the examination of a beast that had 
been afflicted with this disease. He promised that we should 
have it; and he forthwith wrote to his agent, desiring that tw'O 
cough cattle should be slaughtered, and that the surgeon of the 
plantation should transmit a report of what he found. This is
