I now pass on to the consideration of each herd separately, giving a 
description of the herd, the temperature charts, and particulars of all re-acting 
cows and their post-mortem appearances on slaughter :— 
Herd I., Leongatha, South Gippsland.—This herd consisted of 51 milking 
cows, the majority being pure Jerseys or Jersey-Ayrshire half-breds. Thirty- 
two of these were cows between 3 and 6 years, and of the remainder not one 
was over 8 years old. The herd had been carefully selected during the previous 
2 years, no animal yielding below 500 gallons of milk per annum, with a pro- 
portionate butter-fat value, being allowed to remain in the herd. All the animals 
were apparently healthy and in sleek milking condition, and were artificially 
fed with hay, chaff, bran, roots, &¢., in winter, and ensilage in summer, 
Shelter-sheds were provided in all the grazing paddocks, and the general manage- 
ment of the herd was in other respects generous and careful. 
The test was applied on 5th and 6th January, 1897. Koch’s tuberculin of 
date 27th October, 1896, was used, in doses varying from 0°3 ¢.c. to 0°5 c.c., 
according to the age and size of the animal, and diluted with 0°5 per cent. 
sterilised solution of carbolic acid. 
Five of the 51 cows gave re-actions, the highest rise in temperature varying 
from 4:4 degrees F. to 2°6 degrees F., and the mean rise varying from 4:1 
degrees F. to 1:0 degrees F. All the animals that re-acted were slaughtered, 
and the temperatures, together with the post-mortem appearances of each, are 
given in Table B. 
This herd was tested a second time in May, 1898, exactly 16 months after 
the first test. Six of the cows had been sold in the meantime on account of 
their failing to yield the standard amount of milk (500 gallons per annum). 
None of the remaining 40 cows, all of which, as already stated, had previously 
withstood the test, re-acted on this occasion.
