C. H. PEABODY. 
On arriving at the farm we obtained the following history : 
August 25th, 1880, Mr. J. bought, in Brighton, 47 head of 
calves, said to have come from Hew York State. On getting a 
short way from Brighton, some of the calves began to cough. 
They arrived at their destination on August 29th. Three or four 
days after one calf died, and then shortly after, four or live a 
week, then three or four a day, until we saw them. 
The following symptoms were observed: A cough, short 
andjharsh, gradually becoming hoarse, and finally assuming a 
muffled sound, was detected, the animals having the appearance 
of great fatigue. The respiration varied from 70 to 112 a 
minute, and was labored and abdominal, and each breath being 
accompanied with a slight cough or groan. Some of the calves 
were constipated, while others had diarrhoea. 
In some of them the appetite remained good until 24 hours 
before death, emaciation gradually taking place. The pulse was 
weak and irregular. The animals stood with their backs arched ; 
the heads down; the hind legs drawn under the body; the fore 
feet spread apart, with the elbows turned outwards. Frothy 
secretions oozed from the nostrils. The coat was staring ; the 
skin shriveled ; the eyes dull, and in a few cases there was an 
abundant discharge of saliva, in which was found contained filaria 
and their eggs, which had been coughed up. On examination of 
the thorax by auscultation, there was a peculiar, in some places a 
crackling sound; in others a loud wheezing, but no complete loss 
of respiration over any part of the lungs. On percussion, an 
abnormal resonance was observed over the greater portion of the 
lungs. The temperature ranged from 103 to 106 F. The dura¬ 
tion of the disease varied from 15 to 20 days. 
Having obtained the history of the disease, we proceeded to 
make the post-mortem of some already dead, and of some destroy¬ 
ed for that purpose. The description of the lesions found in one 
will, with slight exceptions, answer for the whole. 
The first animal examined had been dead about 24 hours. In 
the thoracic cavity, we found an abnormal amount of serum ; the 
membrane lining it was healthy, and the pericardium without 
patches of lymph or false membrane. The heart was filled
