"A Russian inventor, as reported In
L'Electricita, has succeeding in devising
a method for the manufacture of perma-
net arc lamp carbons, and this in a very
simple manner. They are composed of the
purest carbon, mixed with finely powdered
simeon carbide, some adhesive material
such as molasses, being used. A mixture
OF 80 per cent. of carbon and 10 per cent
OF the silicon carbide is stated to be a good
composition for the purpose, though the
proportions can be varied indefinitely. The
electrodes too, can be made with core
of the carbide, or the latter may be com
bined with any conducting material such
as carbon, to form the core. Since silicon
CARBIDE can only be produced by the action
OF temperature approximately that of
the arc, it contains no volatile ingredients
and has the highest resistance to oxida-
ton of all known substances and as II
as promising excellent results. From the
fact, however, of the carbide not being a
conductor it is not possible to use it as
an arc lamp electrode except in combina-
ton with carbon
People who rely upon domestic filters
to purify water for household purposes
will be surprised at statements made on
the authority of the board of health or
Maryland that such filters may steadily
tf-sa
culture beds for bacteria, says the New
York Evening Post. An example cited is
that in the case of a man in Baltimore
who sends the whole water supply of his
house through a large filter, and subse-
quenuy puts his drinking water through
one of the small domestic filters common
IN the market A test showed that on a
day when the city taps were running $40
bacteria to the cubic centimeter, the large
filter was delivering $500 bacteria in the
same quantity of water. When the large
litter was repacked, only nine bacteria
per centimeter got through it, but this
same water when passed through the
small filter came out with seventy-one bac-
terra per centimeter. A further example
cited is from the office of the Baltimore
health department, where a filter, sup
posed to be the best in the market, was
in use The effectiveness of that filter was
so short-hved that the precaution was OBJ
served of boiling the water after it was
filtered.
The name of "Dreyfus' has been in
everybody's mouth for several years past
and in the light of recent events it might
he of interest to learn something anthem
tic about the origin eff the family of the
unfortunate eX-captain, 1t was generally
supposed that his family came originally
from the French town of Troyes-the
birthplace of the famous Rabbi Rashi-
and has thence deducted the family name.
This is not correct. According to the care
full researches in the records recently pub
lished in BrulPs Jewish Annals it Is al
most certain that the name of Dreyfus is
deducted from the city of Treves Ger
man, Trier), which was called Augusta
TreviTorum by the Romans, this name be-
ing shortened into Treviris later on. The
first of the Dreyfus family coming from
Treves was Rabbi Joseph Treves son of
Rabbi Jochanaus the German (AshkenasD
who lived at Marseilles about the middle
of the fourteenth century Treves was
then German and 1t appears that Rabbi
Joseph emigrated from Treves to France.
One son of Rabbi Joseph, Rabbi Matatia
Treves, was chief rabbi of France; he
founded a Jewish seminary in Paris and
was counted among the great men of his
time. His descendants in turn emigrated
to Germany, Italy and Russia and all be-
ing rabbis, many of them were distinguish
still retains the name of Treves, while
their German and Russian relatives have
adopted the name of Dreyfus.
"A patent has recently been granted to
a New York inventor for a device by
means of which buildings ships, mines
and boiler rooms are constantly supplied
with fresh air, free exit being provided
for the foul and vitiated air says the
Scientific American. The contrivance con-
sists of a tubular casing adapted for in
serting in a circular opening in the roof
of building or the deck of a vessel. In
side of the casing sleeve is so supported
as to leave an air-pasSage between the
casing and the sleeve. Mounted in the
sleeve is a tube provided internally with
a spider or frame, and at its upper end
with a rotatable ingress tube. This ingress
tube likewise has a spider, or frame, on
which a rod is centrally pivoted. The up
per end of the casing is inclosed by
hood formed with a conical end, through
which the ingress tube passes. With the
conical end of the hood an ingress tube
as connected which communicates with the
interior of the hood. These ingress and
egress tubes are curved in opposite direc-
tions, and are mounted to swing in such
a manner that the ingress tube shall con-
stantly present its opening to the wind.
The ingress tube continually forces a col
umn of air downward through the build
or vitiated air to escape. Any vacuum
formed by ventilation, it is said, will be
Immediately tlled by the air pressed inro
the cold tube entering a room at the bot
tom. The ventilator at the rear or leeward
Of the hood constitutes an alr-passage, ere
ating vacuum below and drawing up the
warm air.
Departmental headaches are a distinct
nalady" remarked a wen-known physl-
clan to a Washington Star reporter, land
it Is somewhat of a Surprise how many
sufferers there are among department
clerks from this trouble The thing seems
10 grow among them and they have their
headaches as regularly as they have their
work. All kinds OF remedies are used, and
while the various proprietary medicines
and ten-minute cures, so-caned, cure for
awhile, they seem TO lose their power to
relieve after frequent use. Lack of ventila-
ton in a majority of cases is probably
the cause, but this does not explain all the
cases, for the reason that in many of the
