Prof. Nothnagel, the Austrian court
physician, traces the grip back to the
ninth century, and says it recurs with
varying intensity for three or four
years. and then dies ont for twenty OF
more years. AS to remedies for it., DR..
Nothnagel seems to be sure only of one
thing, and that is that antipyrine should
not be resorted to.

ingot of steel thirty inches in width and
twelve inches in thickness. A mighty
foot holds the ingot in place, and the
knife descends and ships off piece as
boy cuts candy. Hydraulic power is
used, and the cut can be made in about

The orange crop of California has
become so large that it can not be mar
keted at paying prices. Thousands of
acres of the land of California are now
bearing young lemon trees. The olive
and fig crops of the state are now profit
able. Experiments in the raising of
Ceylon tea in Southern California will
soon be tried.
"A blue rose is among the impossi-
bilities There is law governing the
coloring of flowers, which is simply
this: The three colors, red, blue and
yellow, never appear in the same spe-
cies OF flowers; any two may exist, but
never the third. Thus we have the red
and yellow roses, but no blue; red and
blue verbenas, but no yellow; yellow
and blue in the various members of the
viola family las pansies, for instance),
but no red; red and yellow gladioli, but
no blue, and so on.
Canada gets her share of natures
bounty to this half of the world this
year, and the bureau of industries re-
ported last week that the grain yield in
Ontario is extraordinarily large. The
wheat crops, spring and fall, are esti-
mated at 80, 5s4, 02G bushels, nearly half
as much again as the crop of 1890 The
oat crop exceeds by 20, 600, 900 bushels
last years light crop and the average
prairie crop is the highest in ten years.
One hundred and forty-eight thousand
fewer acres were sown in barley than
last year. but the yield is Sal, 1877
bushels more.
Experiments recently conducted in
the school of physiology in Paris,
France, have demonstrated beyond per-
adventure that the kernel Of the oat
contains, three medicinal principles, the
first of which acts to calm, soothe and
tone up the brain and nerves, the Sec
ond yielding phosphorus to weakened
and hungry nerve tissues, and the third,
residing in the husk of the oat or oat-
meal. to act as a laxative and anti-con-
gestive on the stomach, liver and bowels.
"A chemist of Vienna has succeeded
in discovering composition which will
make even the slight material of ballet
dancers dresses fre-proof. The prince
of Lichtenstein gave this composition
first trial on the stage in his own palace
in the presence of a numerous company.
The rise of the curtain discovered two
life-sized dolls, dressed as ballet girls,
to both of which light was applied.
One of the dolls was rapidly reduced to
ashes. while the other, we'll saturated
with the protective composition, escaped
with small hole in the Dress
