parasites. The third outbreak took place in July last, on the 
farm of Mr. 8. P. Swift, Cuba, Alleghany county, N. Y. Nine- 
teen calves were attacked, eleven of which had died at the time 
of my visit, and all the cows on the farm coughed and looked 
badly. The cows with which the malady probably originated, 
erazed on a partially cleared field, full of stumps and brush, 
and abounding in springs and marshy places. They were 
driven home to milk along a road between the fields occupied 
by the two lots of calves, and could easily interchange courte- 
sies with them over the fences. Seventeen of the calves kept 
in one field got water from a deep, enclosed well in the centre 
of the field, while the remaining two never had water but 
only milk. The calves lived, on an average, from nine to 
fifteen days after they were attacked. Treatment, as recom- 
mended, thoroughly destroyed the adult worms, as I failed to 
find one in the bronchial ramifications of a calf examined 
and which had been but twice fumigated, while in those that 
died before the treatment I had prescribed had been put in 
practice an abundance of worms were found. The yearlings 
on the same farm, kept on a separate field and without any 
means of communication with the cows or calves, escaped the 
disease. 
An incident which occurred while one of Mr. Swift’s calves 
was being skinned, throws some doubt on the fatality being 
due to the worms alone. A cat which licked some of the blood 
died on the spot, and before the skin was separated from the 
body; the body of this calf—the only one skinned—is 
further said to have appeared much infiltrated with black 
blood, which points to bloody murrain—charbon—as the imme- 
diate cause of death in this case at least. A cow, too, had 
suffered some time previously from an equivocal swelling on 
the jaw, which burst and discharged an unhealthy sanious 
liquid. 
This complaint is probably much more frequent in calves in 
this countgy than has been yet recognized, and with our con- 
stant importations of English long-wooled sheep it will be a 
marvel if we fail to import their pulmonary parasite. 
In describing the disease it will be convenient to consider
