Herr J. Workman produced curvatures
in growing plants by causing radiant heat
to strike on one side only. Sometimes
plant bent itself toward, but in other In
stances the plant curved away from, the
source of the heat.
The first discovery of prehistoric mines
has recently been made in France. The
mines are flint ones, and are situated IN
miocene strata near Mur.de-Barrez Several
picks of stays antlers with other human
relics have been discovered on the ancient
floor of the excavation. Here and there
the marks of the picks of neolithic man
are still visible on the walls of the work
ings.
The British Commissioners of Northern
Lights have issued the necessary instruc'
tions to proceed with the erection of
large mineral oil gas works on the rock
islet known as Ailsa Craig. Gas to the
amount of 1000 cubic feet per hour, and
of 80 standard candle power, can be manu-
featured. The gas, besides lighting the
new lighthouse will be employed in the
gas engines of the fog apparatus.
Fame and fortune await the discoverer
of an efficient method of so consuming coal
that none of its constituent and combust-
ible particles can escape into the atmos-
phere of large cities, with the two-fold re.
suit of preventing pecuniary loss and SAM.

damage done to buildings and the injury
done to the public health through the
breathing of polluted atmosphere.

referring them to the insobaric conditions

Speaking of the origin of the Aryans,
Professor A. H. Sayce says: 1.-The evil
dence is now all tending to show that the
districts in the neighborhood If the Baltic
were those from which the Aryan Ian.
gusges first radiated, and where the race
or races who spoke them originally dwelt.
The Aryan invaders of northwestern India
could only have been an off.shoot of the
primitive stock, speedily absorbed into the
earlier population of the country as they
advanced southwark, and to speak of 'our
Indian brethren is as absurd and false as
TO claim relationship with the negroes of
the United States because they now use an

A varnish has been invented in Germany
for foundry patterns and machinery. 1t
dries, leaving a smooth surface almost as
soon as it is applied. It is thus prepared:
Thirty Lounds of shellac, 10 pounds of
Manila copal and 10 pounds of Zanzibar
copal are placed in vessel which is heated
externally by steam, and stirred during
from four to six hours, after which $50
parts of the finest potato spirit are added,
and the whole heated for four hours to 81.
This liquid is dyed by the addition of
orange color, and can then be applied as a
paint on wood. When used for painting
and glazing machinery it consists of 50
pounds of shellac, pounds of Manila CO.
pal and $50 pounds of spirit.
