Two French biologists have con-
cluded that microbes are not killed di-
rectly by the electric currents ordinarily
used in medical work, but that the OBJ

An enthusiastic entomologist Is re-
ceiving daily from the local lineman the

Some months age Prof. Schiaparelli
announced the astonishing conclusion
that the planet Mercury rotates on its
axis in the same period of tihe in which
1t revolves around the sun, and the
eminent italian astronomer has now
brought forward evidence tending to a
similar conclusion with regard to Venus.
II these views prove correct, both Mer-
curry and Venus must turn one side con-

"A recent communication to the
Academic de Medicine respecting DR..
Mesnet's Investigations as to stigmata,
or chches as they are now often called,
shows that If pressure on tho skin OF
susceptible subjects is made in the form
OF letters, such letters are clearly dis
tinguishable when nervous derange-
ment causes the skin to change color.
In one experiment the words LA Ma
ture" were traced out on patients
neck, and the letters in a few minutes
developed in color. 1t is observed that
people susceptible to stigmata are hys-
terical or epileptic, and frequently OK

Great Britain is the center OF the
small fruit industry of the world. Ac-
cording to recent statistics, the areas
devoted to small fruit culture there, in
including the cultivation between the
trees in orchards, aggregate 4S,612 acres.
The annual value to the growers aver
ages from S1s, 900, 900 to $50, 900, 900. The
industry has been veritable boon to
English agriculturists. Small fruit
growing is taking the place of unprofit-
able root and grain crops. In the coun-
ty of Kent alone there are about so,
900 persons engaged as growers, pickers
and packers in the production of jams,
and over 100000 tons of sugar is used
annually in the industry.-S Fran

Wood brought TO mirror polish is
coming into use for ornamental pur-
poses in Germany, and has this advan-
tage, that, unlike metal, it is not af-
fected by moisture. The stuff is first
treated with bath of caustic alkali for
two or three days, at a temperature be-
tween 1854 degrees and 1877 degrees F..
Next comes dip in hydrosulphate Of
calcium, for from twenty-four to thirty
six hours, after which concentrated
solution of sulphur is added. After
another soak in an acetate Of lead solu-
tion, at 95 degrees to 100 degrees F., it
is thoroughly dried and polished with
lead, tin or zinc, as may be desired,
when it resembles shining metal..-Sci-
