80 QUEENSLAND AGRICULTURAL JOURNAL. [1 Jury, 1899. 
It will be seen from this table that no indication of tuberculosis could be 
drawn from the temperatures, and there was no other sign of a re-action. 
Particulars concerning the life history and post-mortem examination of these: 
animals are as follow :— 
No. 1 Cow.—A. six-year-old half-bred Shorthorn cow, recently calved, in 
low condition, but an excellent milker. Two years previously she had had an 
attack of acute pleurisy, but recovered after 14 days’ veterinary treatment. 
On being slaughtered, the respiratory, digestive, circulatory, urinary, and 
generative organs were carefully examined and minutely dissected, as also were 
the various groups of lymphatic glands, the supra-renal capsules, and the brain 
and spinal cord; and with. the exception of a fibrous pleuritic adhesion about 
3 inches in diameter, evidently the remains of the acute pleurisy, no lesion, 
tubercular or other, was found. 
Wo. 2 Cow.—An aged Shorthorn cow, in full milk and good condition. No 
previous history of serious illness, but selected by the manager as the most 
ikely of the others to be diseased on account of occasional capriciousness of 
appetite and attacks of fcetid diarrhoea and indigestion. A similarly complete 
and careful post-mortem examination of this cow was made, with the result that 
no tubercular lesion was found. ‘The liver was, however, somewhat extensively 
diseased, being affected with both fluke (Déstomum hepaticum) and parasitic 
cysts. A number of the ducts of the liver had undergone calcareous degenera- 
tion, and contained the calcified dé/ris of flukes, but no living fluke was found. 
In the substance of the liver were many parasitic cysts, the contents of nota 
few of which had undergone degeneration, the wall or capsule of each cyst 
being, however, well defined and shrivelled, and without sign of coalescence. 
[Another case,* which affords evidence that when tuberculin gives a 
negative result tuberculosis is not present, has recently been investigated. 
In the course of the post-mortem examination of calves used for the 
cultivation of calf vaccine lymph I found a twelve-weeks-old calf badly 
affected with tuberculosis, the parts most diseased being the lymphatic glands 
(especially the mammary or udder, inguinal or groin, bronchial and sternal 
groups), the lungs, pleura, and liver. There was also a large broken-down 
tubercular abscess at the umbilicus (navel). Although the fact that the 
disease was generalised in so young a calf might have led to the sup- 
position that it had been contracted from the dam, the calf having 
sucked up to the time of killing, the further fact that the alimen- 
tary canal did not show the least trace of any tuberculous lesion seemed 
to negative such a supposition. On the other hand, seeing that the lesions in 
the udder and groin lymphatics, which drain lymph from the region of the 
umbilicus, were apparently of greater age than ae in other parts of the body 
—those in the lungs and liver being apparently recent, while those in the pleura 
were in quite an initial stage—it appeared that the disease had progressively 
invaded the lymphatic glands situated between the umbilicus and the outlet of 
the main lymphatic duct into the blood stream, whence the lungs, liver, &c., 
ultimately became affected ; and I concluded that the disease had been contracted 
by inoculation at the umbilicus (shortly after birth, and possibly before the 
wound caused by the severance of the umbilical cord had properly healed), 
probably through the calf lying on tuberele-infected litter, débris, or other 
matter. The dam of the calf, about 3 years and 3 months old, was then tested 
with tuberculin. The test gave a negative result, there being no rise of tempera~ 
ture or other symptom of a re-action at any time after the injection. The 
chairman then decided to haye a bacteriological examination (for the tubercle 
bacillus) of the milk of the cow, of the vaccine lymph yielded by the calf, and 
of the tubercular lesions of the calf. The examination was made by Dr. Cherry, 
eet animal tested in this case is not one of the 267 cattle mentioned at the outset of this 
report.
