C., down to roo A. d., when it practical

bodies were embalmed in Egypt, o.
which the greater part are yet con

Experiments have been made by
Dr.. Buchner in submitting working
bees to regimen of alcoholizcd honey.
The efcet is astonishing. They revolt
against their queen and give themselves
over to idleness, briganda re and pillage

-Fifty-two trades unions, with a
membership of over $50 900 have made
returns for July to the labor depart

members were unemployed, as COM

Mr.. Jansen recently exhibited to
the French Academy of Sciences the
cloclxwork that viii register the OBJ
servatioDs of the instruments placed in
the observatory on top of Mount Blanc.
1t requires winding up only once in
eight months, and is fabricated with a
material that has been exposed to a
cold of so degrees below zero without
freezing.
"A new anthropometric test of sem
sitiveness has been designed by DR..
Cation. A band of color showing all
the sixty-five shades of blue, is slowly
passed before the eyes, and the subject
makes dot for every shade detected.
AS far as the experiments have pro-
ceeded only about twenty shades are
generally discovered. In one case, how
ever, dyer detected about forty.
Soap is found to be one of the best
known sterilizers of water suspected
of Infection. 1t seems that for long
time after the cholera epidemic of last
summer, the people of Hamburg were
afraid even to battle themselves with
Elbe water, but NM. Forster and
of that city, claim to have
shown by experiment that ordinary
toilet soap, added at the rate of an |
ounce to about twelve quarts of water,
will kill the cholera bacilli in about |
ten minutes.
According to the British Medical |
Journal, DR.. Troitzl1i states that he
has found that new and uncut bread |
contains no heterogeneous, as the
heat necessary to bake the bread is suf-
hcient to kill them all. As soon, how
ever, as the bread is cut and is allowed
20 lie about uncovered, not only harm
ess, but also pathogenic microbes find
n 1t an excellent nutrient medium.
white or wheatpeal bread is better

after contains greater percentage of

The bones of human being are
