NOTES ON THE CONDITION OF THE EIGHT ANIMALS. 
Since the first testing, the big roan cow “Diana” gave birth to a fine 
healthy-looking male calf, which unfortunately, through some misunderstanding, 
was killed when only a few days old; itis, however, satisfactory to know that the 
lungs, glands, and internal organs of this calf were perfectly sound aud healthy, 
while the mother (from the time of calving) was noticed to lose condition 
considerably ; the milk yield was very small and poor in quality in consequence 
of the progress the disease had made in each of the four quarters of the udder. 
The other five cows had shown no alteration whatever in their physical 
condition, while the young bull and the heifer had both made very decided 
improvement—in fact, both looked the picture ot health. ‘With the exception 
of Diana, there was nothing to indicate that any of the animals were tubercular 
in the slightest degree. 
After the testing, the five cows—Dinah, Annie, Bluebell, Floss, and Snow- 
drop—were returned to the isolated paddock; while the newly-calved cow 
Diana, the heifer Hessie, and the little bull Young Randwick were killed, and 
on post-mortem the following appearances were revealed :— 
Diana.—DLungs filled with small tubercular deposits. Bronchial and 
posterior pharyngeal glands not enlarged, but caseous milliary 
tubercles on the mesentery. Spleen mottled. All four quarters of 
the mammary gland enlarged and tubercular. 
Hessie.—Lungs and bronchial glands apparently healthy. The 
mesenteric glands were tubercular, while on the mucous membrane 
of the intestine there were several large tubercular ulcers. 
Young Randwick.—Large caseating patch deeply seated on the inner 
aspect of the right lung; also numerous miiliary tubercles on the 
dorsal surface of both right and left lungs. Bronchial and posterior 
pharyngeal glands enlarged, and showed small tubercles on cut 
surface. Numerous small caseating tubercles all over the liver. 
Mesenteric glands enlarged, indurated, and highly pigmented. 
Throughout the small intestine there were numerous ulcerating 
tubercles on the mucous membrane. 
There can be very little doubt that the lesions found in the intestines of 
the young bull and the heifer were the result of ingesting some virulent tuber- 
cular material, and derived from either one or both of the following sources :— 
1. By being fed when young on the milk from a cow suffering from tubereular 
mammitis (probably Diana’s milk). 2. By ingesting some tubercular expec- 
toration which had been coughed up into the feed-boxes or mangers from one 
of the cows with infected lungs. 
It should be specially pointed out that the application of the tuberculin 
test is only one factor in éliminating tuberculosis from a dairy herd ; therefore 
every possible means should be afforded for adopting the other equally necessary 
preventive measures—zi.e., after testing the entire herd periodically (every six 
months), viz. :— 
(1) The reacting animals should be separated as far as possible from 
the healthy. ; 
(2) Kill all the evidently sick animals immediately. : 
(3) Rear the calves of the cows which react but otherwise appear 
healthy or at least only slightly attacked. 
(4) Remove the same immediately after birth from the infected sheds 
or yards; place them in the specially-set-aside healthy division ; 
and protect them from further infection, especially from feeding 
with suspected milk. 
(5) Following the lines adopted by Prof. Bang, it is advisable to 
sterilise all milk intended as food for calves. 
(8) Carefully disinfect the interior of the various sheds used for housing 
cattle, first, with 1 in 1,000 bichloride of mercury, and afterwards 
with limewash mixture containing 1 in 1,000 bichloride of mercury.
