TUBERCULOSIS.

Which had, since the test, lost flesh rapidly and developed an 
aggravating cough. Suspecting tuberculosis, she was at once 
destroyed and an autopsy held which revealed pulmonary and 
intestinal tuberculosis with enlargement of the lymphatic glands 
of the mesentary. In fact this was one of the worst cases of 
tuberculosis that I have had an opportunity to examine after 
death. 
. 0n J une 22d ’ the bul1 and native cow which showed a reac¬ 
tion of only 1.1° on the first test, and none on the second, were 
also destroyed. The autopsy on both of these animals revealed 
intestinal tuberculosis with enlargement of the internal lym¬ 
phatics. The three remaining animals have not yet been 
s aughtered, but are isolated and will be tested with tuberculin 
later in the fall, and if they show the slightest reaction they will 
be slaughtered at that time. 
The question as to what elevation of temperature constitutes 
a reaction is at the present time an open one. I have seen no 
cases reported where the animal was condemned with a reaction 
of only one degree unless the general symptoms were prominent 
enough to make a diagnosis possible by a physical examina- 
tion. 
Dr. Conrow, m a communication to the Veterinary Magazine , 
January, 1894, reports the destruction of one case that showed 
the physical signs of tuberculosis, and with tuberculin gave a 
reaction of 1.4-4 but upon holding a post-mortem no tubercles 
were found. Dr. Conrow does not state whether or not a care¬ 
ful examination of the bones and all other tissues of the body 
v as made. If such an examination had been made it is more 
than probable that tuberculosis in some one of its many hiding 
piaces would have been found. 
From my own experience I am led to believe that any eleva¬ 
tion of temperature, that continues over two or more readings, 
above the highest normal variation during a period of twelve 
hours before injection is diagnostic of tuberculosis, and that if 
we expect to completely eradicate the disease from our herds we 
must take this as a standard. It would be much more profitable
