In seeking for substance which
would destroy the microscopic ami

drinking purposes, DR. Langfeldt
found that citric acid (one-ffth

PROFESSOR CARLO PAvEsI, Of Italy,
proposes as an improved disinfectant
solution composed of chloride of
lime, camphor and glycerine. This
mixture is capable of being used in
all cases in which phenic acid is now
employed, and its odor is less dis
agreeable, less irritating and less
toxic than that of the latter 1t is
said to at once arrest the putrefaction
of animal bodies, and is highly com

The Scientific American says that
the prejudice against American hem

and English tanners now appreciate
its excellent qualities. Its capabili-
ties for resisting water and with
standing wear by attrition in the

be quite equal to those of the best
English sole leather, and greatly SUI
perior to the leather of English

RECENT experiments by M. Jailett
show that when alcohol is taken in
to the stomach it is partly decom-
posed there and in the liver, and is
carried by the veins into the lungs.
a small quantity of it is then thrown

ether is burned up in the system.

HE English journals, in discussing
Ihe question of domestic poisons,
