change occurred in their condition until the excessive drought dried up the 
grass, when all of them lost flesh. 
September 19th.—The four cows, bull and calf, were slaughtered in Brigh¬ 
ton. 
Autopsies. —The roan cow (No. 1, Maine) was first killed. On removing 
the right lung it was found adherent to the ribs at its lower border, about five 
inches in length and four in width; that portion of the lung appeared wasted, 
and on the inner surface was a cicatrix, as if suppuration had taken place, and 
ulceration sufficient to open the cyst, causing a discharge of the contents of the 
cyst into the thorax. A small cyst was found in the immediate vicinity. There 
was also adhesion of the left lung. All the other organs appeared healthy; the 
uterus was empty. 
The next killed was No. 3, Maine cow. All the viscera, both thoracic and 
abdominal, were healthy ; the uterus contained a well developed foetus. 
The No. 4 Maine cow had a small portion of the pulmonary adherent to the 
costal pleura ; the lungs were healthy, as were all tlie other organs ; the uterus 
contained a foetus not more than four weeks old. 
No. 1, Weston cow.—The superior part of the large lobe of the left lung was 
adherent to the ribs and to the vertebrse, and in the lung was a cyst containing 
a mass about three inches in length, and two in breadth. Otherwise, the organs 
were perfectly healthy. The uterus contained a foetus about two months old. 
All the organs of the bull and calf were healthy. 
Two or three cows owned by Avery Whiting, one of which was attacked 
by the disease in the latter part of April, the other the 22d of June, were sent 
to my place in West Newton on the 31st of July. The first mentioned calved a 
few days previous to the attack, and on the 24th of June, when i first saw her, 
had a good appetite, and gave about seven quarts of milk per day, was thin of 
flesh, and coughed frequently. 
The other showed the first symptoms of illness on the 22d of June, previous 
to which she gave three gallons of milk per day, and was in good flesh. On 
the 24th of June she presented the following symptoms: 
The pulse was eighty per minute, small and wiry; respiration thirty, short 
and apparently painful; the coat stared ; the eyes were dull; and considerable 
saliva flowed from the mouth. By percussion, a dull, flat sound was emitted 
on both sides of the thorax. The appetite was entirely lost. Occasional visits 
were made. No material chauge in the symptoms appeared until the 13th of 
July, when the appetite began to improve. 
Her condition, August 1st, was little better than a living skeleton ; the hair 
stood out and had an unhealthy appearance; she coughed almost incessently 
both night and day; the secretion of milk was lost, and with the best of food 
for producing milk,—green grass and sweet corn fodder,—not over half a pint a 
day could be drawn. 
The appetite was voracious, yet but little improvement was manifest in her 
condition for two months, when the cough partly subsided and she began to 
gain in flesh, and continued to do so until she was slaughtered, yet no milk was 
secreted. No one would suspect she was diseased unless she was compelled to 
move a few steps quickly, when a lit of coughiug would invariably follow. 
With the first mentioned cow, but little improvement was produced in her 
condition.
