EXTRACTS FROM EXCHANGES. 
in the lungs, pleura and small intestine, but the genitalia were 
free. The foetus was likewise tuberculous, greyish tubercles 
being present on the surface of the liver, the lymphatic glands 
containing miliary tubercles in a state of cheesy degeneration, 
being conglomerated together in the hepatic omentum, both 
glands and tubercles containing Koch’s tubercle bacilli. Now, 
Nocard had always taught that the foetus could only become tu¬ 
bercular when the uterus of the mother was tubercular, i. e., 
only through a maternal source. But this case seems to prove 
that the foetus can become tuberculous without the uterus being 
tubercular, i. e ., from foetal source per se. For he found the 
vaginal and uterine mucous membrane normal; at least he could 
discover no tubercles nor bacilli, nor cheesy degeneration, nor 
suppurations upon the maternal side of the uterus. On the con¬ 
trary, the only evidence of disease in the genitalia or their con¬ 
tents existed on the foetal side, i . <?., in the placental cotyledons, 
seeming to prove that the foetus can become tubercular in litero , 
without the uterus being tubercular. There were no round mil¬ 
iary tubercles in the cotyledons, but a yellow cheesy, diffuse in¬ 
filtration containing Koch’s tubercle bacilli. It is very easy for 
the blood in the capillaries of the placental villi, surrounded as 
they are or walled in as they were with tubercular areas, to re¬ 
ceive the bacilli from the placenta and send them coursing 
through the umbilical vein to the liver and lymphatic glands of 
the foetus. How the foetal placenta is infected, the surrounding 
uterus being normal, is hard to say; but one thing is certain, 
and that is that a foetus can become tubercular in an apparently 
healthy uterus, making a marked exception to N.’s.rule that a 
foetus can only become tubercular through the agency of a tu¬ 
bercular uterus. Is the foetus infected through the male sper- 
matozoan, a thing hardly likely ? What is the explanation ?—

Treatment of Hoof Cancer. —A decided advance has 
been made in the treatment of hoof cancer lately, but only after 
patient and painstaking application of the most successful rem¬ 
edies. Nitrate of lead lias during the last few years been used 
with encouraging results in Germany. Concurrently with others 
the author believes that the careful removal of all the under¬ 
mined and pathological tissue is of the utmost importance ; this 
having been done and all redundant vegetations checked by the 
use of the cautery, the author employs lead nitrate. He selects 
a well-drained stall, well strewn with straw, appoints a man 
solely to water the animal and keep the stall clean ; then remov-
