Herd VIII., Warrnambool, Western District.—This herd consisted of 13 
Shorthorn and Jersey cows in prime condition. All the cows were home bred, 
no cows haying been introduced into the herd for a number of years.* 
_ ‘Test applied, 26th and 27th February, 1898—Koch’s tuberculin; dose, 
0-4 c.c. to 0°5 c.c. 
None of the cows re-acted definitely. In one the temperature rose 2:1 
degrees I?., but this cow had calved 24 hours previous to injection, and was 
suffering from congestion of the vulva and vagina. 
Herd I[X., Leongatha, South Gippsland.—This herd comprised 7 half-bred. 
Jersey cows recently purchased for their milking qualities. They were in fair 
condition and well cared for. 
Test applied, 4th May, 1898—Koch’s tuberculin; dose, 0:4 ¢.c. to 0°5 c.c. 
One of the 7 cows re-acted, showing a maximum rise in temperature of 
2'4 degrees F., and a mean rise of 1:7 degrees F. during 21 hours. Particulars 
regarding this cow are given in Table G.

II.—_SOME OF THE LESSONS TO BE DERIVED FROM THE PARTICULARS SET 
: OUT ABOVE. 
_ Firstly, as to the distribution of the disease in the animal. On analysing 
the tubercular lesions present in the 23 cows slaughtered, it will be found’ that 
14 of the 23 were affected with “ generalised tuberculosis ”’—that is to say, that 
the disease existed in two or more organs or groups of organs, remote from one 
another, and unconnected with each other except by the blood stream. The 14 
were—Nos. 2 and 4, Herd L., Table B; No. 1, Herd ZZ, Table C; Nos. il Yh, 8}, 
and 5, Herd V., Table D; No.1, Herd VZ., Table B; Nos. 1, 2, 3, 4, and 9, 
Herd VII, Table F; and No.1, Herd ZX, Table G. The remainine 9 were 
cases of ‘localised tuberculosis,” in which the lesions had not spre beyond 
the organs or groups of organs affected and their special lymphatic glands. 
These 9 were—Nos. 1, 3, and 5, Herd L., Table B; Nos. 2 and 3, Herd VI, 
Table HE; and Nos. 5, 6, 7, and 8, Herd VIZ, Table F. 
Secondly, as to the probable method of infection. If the anatomical 
situation and pathological age and condition of the various lesions be analysed, 
an approximate idea of the method of infection in about half the cases may be 
obtained. For instance, in the case of 6 of the cows (viz., Nos. 1 and 3, Herd 
I., Table B; No. 8, Herd VL, Table E; and Nos. 5. 6, and 7, Herd VIL, 
Table F) it may be assumed that the primary infection was by ingestion. In 
the case of 5 others (viz., No. 5, Herd I, Table B; No. 1, Herd 77. Table C;

*'The owner writes 10th March, 1898 :—-‘ As _to the 13 cows tested, I have had the herd for 
the last 12 years, and have culled heavily for milk supply. The original animals were either 
Durham or Durham crossed with Ayrshire. Tvejected any animal which did not give a minimum 
of 500 gallons of milk annually, and reared the heifer calves of those retained in the herd. These 
cows have never had bought cattle running among them, and now have well-sheltered paddocks 
to run in. The young stock have always been carefully reared on healthy fresh milk separated 
on the place and kept in clean buckets until wanted. One cow is very old, and is kept more as a 
pet and breeder than for present profit. Most run from 3 to 5 years,
