TUBERCULOSIS. 
there before the State authorities I had ample time to stud) 
carefully the history and surroundings of the herd. 
From Gr. W. Gowell, Superintendent of farm, I learned tha! 
for the past eight or ten years there occurred an occasional death 
among the cattle, and as nearly as I could judge from his 
description these animals were affected with the same disease that 
prevailed at this examination. 
The trouble was evidently a pulmonary one, a more or less 
persistent cough, irregular or hurried breathing and emaciation 
being witnessed in all. 
T was led to examine the hygienic surroundings. The barn is 
a large one and has ample room for the stock. It is well lighted 
aud thoroughly ventilated ; the air being surprisingly pure as I 
entered the building early in the morning. The stalls are kept 
very clean, as the animals themselves show. The manure is 
thrown in the basement, but a free current of air prevents any 
appreciable odor from rising to the stable. The water is from a 
cistern which, being above the level of any stable drainage, is pure 
aud wholesome. The feeding is judicious in every sense, and the 
food, both grain and hay, is of the best quality. 
From the history of previous cases, and upon examining a few 
of the cattle that presented the most marked symptoms, I was 
able to diagnose the disease as tuberculosis beyond any reason¬ 
able doubt. 
Upon the arrival of the State authorities it was decided to 
destroy some of the worst cases for post-mortem purposes. The 
animals thus selected were some that State Veterinarian Bailey 
had previously examined and placed by themselves in the horse 
barn. I will refer to some of them by name and give the lesions 
presented. Cow Pansy presented numerous miliary tubercles 
throughout the left lung, and in the right were masses of tuber¬ 
cular deposits of various sizes, situated chiefly near the apex of 
the lung. These masses had become cheesy or calcareous. 
Hyacinth presented smaller aggregations of grayish white 
nodules throughout the substance of both lungs. 
Flossy —Both lungs affected ; in the right lung near its centre 
was noticed a large abscess, due to softening and breaking down
