the tumors without ever noticing reactive phenomena 
comparable to the preceeding (at the seat of injection). 
(5) Consequently we think that one may try subcutan- 
eous injections of serum in the vicinity of inoperable tu- 
mors when these might become operable after changes in 
the neighboring parts, or when they are accompanied by 
pain or edema due to compression. Normal ass’s serum 
will be employed in preference toass’s serum previously 
inocculated with epithelioma juice. At the recent meet- 
ing of the Societe de Dermatologie et de Syphilographie, 
Augagneur (Sem. Med.) reported the results of some ex- 
periments of the same kind made by him in cases of can- 
cer and syphilis. In patients suffering from epithelioma 
of the skin he injected ass’s serum in doses of 8, 10, and 
12cm. After the injection the tumor became turgid and 
bleeding, then after a time it diminished in size; this 
effect was, however, only temporary. He observed simi- 
lar local phenomena after injections of serum in patients 
with simple vegetations. The injections have the same 
effect in persons suffering from lupus; after a peroid of 
cedema and congestion there ensues a passing shrinkage. 
Formerly he tried the injections in syphilitic subjects. 
He made particular mention of one case of exuberant 
facial and lingual syphiloma, which has improved fora 
month. He makes the injections into the cellular tissue. 
Urticaria often occurs about the site of puncture, and 
there is some rise of temperature. On two occasions 
albuminuria occurred.—British Medical Journal. 
Flies and Infection.—Even hash is liable to get flies not 
only onto but intoit. Dr. G. M. Sternberg, Surgeon Gen- 
eral United States Army, spoke at the last meeting of the 
American Public Health Association at Buffalo, N, Y., on 
contamination of food by flies, and said that it was by no - 
means an infrequent cause of the spread of disease. Diph- 
theria, cholera, and other germ diseases, he said, could 
very often be traced directly to flies.
