Above all things, however, we can exercise due circumspection 
in obtaining the lymph; one should ever remember “The wind 
sowetli but the storm reapeth,” i. e. those who inoculate with the 
lymph concomitantly ichorous elements, must expect gangrenous 
processes to follow on different parts of the body, especially the 
posterior parts, and which even with the best treatment, generally 
either terminate lethally or result in the animal in question losing 
the tail; hence lungs which offer the least appearance of suspicion 
must be carefully avoided as objects from which to obtain lymph. 
The same is best obtained from the interstitial connective tissue 
of the lungs, and from animals by which the disease is present in 
its early stages, and which are absolutely free from other com 
plications. One wins the lymph by allowing the same to flow 
from the cut surface into a vessel conveniently placed to receive 
it; such fluid should be placed in a well corked bottle for twenty- 
four hours, and then carefully filtered and placed in a thoroughly 
close bottle under water and in the dark until wanted for inocula¬ 
tion. All experienced inoculators are united in expressing the 
impossibility which has met their endeavors to retain such lymph 
pure and active for any length of time, and this fact offers one 
of the great obstructions to the extension of inoculation in refer¬ 
ence to this disease. Of late Goeroldt has recommended placing 
a piece of chloral-hydrat, of the size of a pin’s head over or on the 
surface of every fifty grammes of filtered lymph, the fluid to be 
then placed in a perfectly clean and disinfected bottle (scalded 
out —B.) the same to be carefdBy sealed and placed under water 
in a cool dark place. While I have not tested this manner of 
treating the lymph (Putz), yet the same recommends itself to 
us, especially as I know Goeroldt as a trustworthy man. 
The great importance of the necessity of great circumspection 
in obtaining, preparing and conserving lymph for inoculation, 
should be self-evident to every one who desires to reduce the 
losses resulting from the same, to the lowest possible degree. At 
the same time we must in no measure neglect to exercise a like 
degree of circumspection in the treatment and care of the inocu¬ 
lated animals, as well as any conditions which may present 
themselves during the action of inoculated disease. Of great
