tion, but the diagnosis as made by the use of the tuberculin 
proved correct in every case and three of the five cows ex¬ 
amined had generalized tuberculosis, i. e., nearly all the 
organs were diseased. In three of the four Jerseys exam¬ 
ined tubercles were found in the udder where they were dis¬ 
charging into the milk. No attempt will be made to write a 
technical description of these post mortem examinations, 
but the following general notes will give the reader an idea 
of the amount of infection demonstrated: 
Kate. (No. 4 in Table I ) Jersey cow, 4 years old. Reaction, -5.8 de¬ 
grees. Killed and examined December 15, 1900. Carefully examined before 
death, but could find no evidence of disease. Cow in good condition with 
considerable internal fat. Had been lame and evidently suffering from 
effect of the injection of tuberculin since December 8. Lungs healthy except 
the lymphatic glands in the lungs which were hard and gritty with calcare¬ 
ous deposits in the tubercles. Kidney healthy, scattering tubercles size of 
pinhead to one-half pea, scattered over the intestines, especially the large in¬ 
testine. Spleen covered with tuberculous growths. Liver with scattering 
tubercles and grit of small size all over surface and through the mass. Inside 
of womb and placenta along with umbilical cord covered with tubercles 
from size of grain of sand to small pea. Small tubercles found in udder. 
Photographs taken of cow and affected glands Carcass burned. 
Kind’s Lee Noble. (No. 2 in Table I.) Jersey cow, four years old. 
Reaction, 0 4 degrees. Killed and examined December 29, 1900. Apparently 
in good health. Glands in lungs and those from the mesenteries affected, 
but not in advanced stage of disease. Well developed tubercles in the udder 
where milk glands were discharging over them. Photographs taken of cow 
before death, and of affected glands. Carcass burned 
Lacy. (No. 5 in Table I.) Jersey cow, four years old. Reaction, 8.9 
degrees. Killed and examined December 29, 1900. Cow apparently healthy. 
All organs apparently healthy, Finally small glands from the mesenteries 
were found with well developod tubercles in the milliary stage. (Millet-seed 
like excretions of calcareous matter encysted in the glands.) Photographs 
taken before and after death, also of glands. Carcass burned. 
L<ee Noble. (No. 2 ill Table II.) Jersey cow, seven years old. Re¬ 
action, 5.1 degrees. Killed and examined January 26, 1901. Though this 
cow was apparently healthy, inside of carcass and organs were found to be 
literally covered and filled with tubercles, the principal affection being in 
the liver, lungs, udder, lymphatic glands, placenta and umbilical cord. 
Hard, gritty, calcareous deposits everywhere. Carcass burned. 
Ambrosia. (No 9 in Table I and No 11 in Table II.) Shorthorn 
cow, three years old. Reaction, 4.8 degrees. Killed and examined May 4, 
1901. Cow apparently in good condition, well supplied with fat and with no 
external evidence of the disease. She had not been eating well for some 
time and we had been unable to get her with calf. Had a small tumor on 
right jaw. Postmortem demonstrated an advanced stage of tuberculosis. 
Ovaries and uterus badly diseased and filled with pus from the breaking 
down tubercles. Beside the sex organs, the spleen, liver and intestines,
