INOCULATION OF BACILLAR PHTHISIS. 
215 
Baumgarten produces new experiments*. When milk, or a 
bacilliferous fresh liquid, which has proved its virulency, is ex¬ 
posed to the temperature of a room, or to warm air, so that it 
putrifies, it will produce but insignificant lesions, and the bacillus 
still conserves its character, viz.: its form and coloring reaction, 
it having then lost only its morbigeneous properties. Then, 
when a mixture is made of putrihed pus with a liquid containing 
fresh bacilli, and this mixture is injected into the anterior cham¬ 
ber of the eye, one may see, notwithstanding the invasion of the 
parasites of fermentation into the tissues, the development of the 
tuberculosis taking place, and may conclude that it is only after 
a long contact of the bacelli with the substances in putrefaction 
that the former lose their power. 
Resistance of the Sputa. —Schill and Fisher [Memoirs sur la 
desinfection des crachats phthisic , 1883), go further, and hold 
that sputa submitted to putrefaction during several weeks retain 
their nociveous power; they have seen sputa in putrefaction pre¬ 
served intact the forty-third day; their bacillar, notwithstanding 
the presence of numerous bacteria of putrefaction, and keep 
maintaining their phthisiogenic power; for when injected into 
guinea-pigs the animals become tuberculous. Their virulent 
property was not doubtful. Kussner confirms these facts. In 
injecting bacilliferous witli ordinary ones he obtained entirely 
different and opposite results. 
The resistance of the sputa to the action of antiseptics is no 
less marked. Absolute alcohol, salicylic acid and anilined water 
act only when in a very high degree of concentration. Plienic 
acid in the proportion of 5 per cent, may act. Dry heat at 100° 
for several hours disinfects them; a coetion of 15 to 20 minutes 
is sufficient to produce the same result. It is especially to the 
spores and to their refractory state that the continuation of the 
deleterious action of the sputa is due.
