1t is not generally known that excessive
palpitation of the heart can be promptly
stopped by bending double, with the head
downward and the arms pendant, so that a
temporary congestion of the upper part of
the body is produced. If the breath be
held at the same time, the effect of this
action is fastened.
There are now 120 women in the Berlin
telephone exchanges 1t has been decided
| to use only women in the future, as it has
been found that their voices are much
more audible than mems, owing to the
higher pitch. The men previously en-
gagged have not been discharged, but have
gradually drifted off to different work In
one of the smaller exchanges there are
fifty women working eight hours day,
only the chief and inspecting staff being
men.
A new departure mas been taken in gifts
intended for the edifcation of the public in
the electric fountain which has been pre-
sented to Lincoln Park, Chicago. The
fountain has over two hundred large jets,
which are artistically intermingled, the
highest of which throws stream of water
to hight of seventy-fve feet. The foun-
tain, when Illuminated, is most beautiful
sight The spray separates into innumer-
able drops, each of which reflects the glitter
of the electric lights, giving the effect of a
shower of diamonds.
1t is now denied that Gutenberg was
the inventor of typography, credit he
has held for centuries. The French his
torian, NJ. Requin, says typography was
known and reduced to practice in Avignon,
France, ten years before Gutenberg APP
peared with his important pretensions.
One Prokop Waldvegel came to Avignon
from Prague, Bohemia, in 1444, and COM
municated to an Israelite. David de Cader-
oso, "a new method of writing" and that
the latter began with manufacturing He
brew types. 1t remains to be seen whether
NJ. Requin can bring "the papers" to
prove his assertion. Old printers will
hesitate to believe the new suggestion of
this Image breaker"
The London Times describes a new
method of treating fbrous plants and
says: 'The various processes to be carried
out at the model fiber factory, which we
have recently been afforded the opportu-
nifty of inspecting, comprise the rapid rot
ting and ungumming of fbrous plants,
automatic breaking scutching, combing
and hacking; spinning into simple or
mixed yarns; cottonizing and woolenizing
fbers to initiate fine cotton or wool, suita-
BILE for the manufacture of various mixed
and cheap fabrics, as well as for fine and
costly goods; bleaching and dyeing the
same. and the rapid drying of fibers by
means of cold air. The factory is in High
street, Lambeth"
A Troy On. " paper says: at is said
that the process of dyeing roses is becom-
ing remumerative branch of industry
with English horticulturists. Instead of
growing new varieties of roses, which is a
process of years, they simply grow ordinary
white roses and dip them in a chemical
solution which in single hour converts
them into the most magnificent yellow
tea roses, the rare scarle. red, or the
peculiar shade of blush violet which
has been one of the favorites of the sea-
son. In a similar way pink roses are
turned into blossoms of the deepest red.
Some years ago, before this branch
of floral chemistry was developed,
the first experiments were successfully
made in France with the popular pink
hortersia, which, by being watered by a
solution of iron, assumed blush shade"
