with the hypodermatic use of anyl nitrite or nitroglycerin. 
Here, the patient instead of being squeezed, rolled, and 
tumbled about, is entirely passive, and will lie for hours with¬ 
out moving or appearing uncomfortable, or as long as forced 
respiration is kept up. Those who have had experience in 
the physiological laboratory, know that in dogs overdosed with 
an anaesthetic, life may be prolonged for indefinite periods 
of time by employing the bellows in connection with 
an opening into the trachea, hence there is no valid reason why 
the same procedure should not obtain where it is desirable to 
save life. It may here be noted that Dr. Geo. E. Fell has in 
this way been instrumental in saving several cases that were 
deemed hopeless ; in one instance the life of a man was pre¬ 
served through forced respiration continued without interrup¬ 
tion for more than thirty hours ; twenty grains of morphia had 
been ingested eighteen hours before a physician was 
summoned. 
Note. —It was my original intention to speak of the other 
anaesthetics in this connection, such as ethyl bromide, ethyl 
chloride, methylen bi-chloride and nitrous oxide, but the 
length to which this paper has grown forbids. Whether I 
shall take them up later remains to be seen. I have, however, 
recently devoted considerable attention to each in the columns 
of the Therapeutic Gazette for September of last year. 
PRELIMINARY REPORTS UPON KOCH’S ANTI-TUBERCULAR 
FLUID, 
Translated by R. Middleton, D.Y.S., Philadelphia, Pa. 
The following communication has been received by the 
“ Vos-Zeit respecting experiments with the Koch fluid, as 
made in Dorpat, Russia, upon cattle suffering from tuberculo¬ 
sis :—At present careful reports are being issued upon the 
inoculations which were undertaken at the veterinary institute 
in this city. After the presence of phthisis pulmonalis had 
been ascertained beyond controversy, by the physical signs 
displayed by the subjects, and also by the finding of the
