The keeping of cats Is the solution
offered by Lieut.. Col. A. Buchanan,
civil surgeon of Amraoti, Berar,
India, for the plague problem that is
now so steadily growing upon the
world IS attention. At Nagpur 70, 600
p9ople have died from plague. and
20,00 at Kalmeshwar. These places
are IL miles apart, and on the road
side between is the village of Aria,
which has had no plague. Cats have
kept the village free from rats. Fol
lowing up the hint, census showed
that the 500, 900 people of the district
of Anraoti had $4,000 cats, aud that
l45 villages having cats in at least
half of the houses had never had the
plague. OF more than 5000 cases of
plague in the district last year, there
we're no cases in groups of houses
containing more than one house pro-
tected by cats. 1t is now known that
the plague Is spread by rats. The gun,
the trap, the ferret, the terrier,
poisons like phosphorus and arsenic,
and bacteria have been suggested as
remedies, but Col. Buchanan believes
that the plague in India will cease
when the cat-which has been over
looked lis recognized as the true rat
eXterminator.
Salt is purified by melting in the
new and rapid English process. The
crude rocksalt is fed automatically to
IA table contained in large furnace,
is then fused and run into troughs,
from which it is drawn at one side of
the furnace into large cauldrons. Air
Is forced into the molten mass and lime
is added. The impurities sink to the
bottom, and the upper portion is
ground aud screened, while the lower
part is used for chemical manure.
The physiological effects of high
frequency currents are traced by two
French experimenters to increase of
body temperature. This gives them
value ia arteriosclerosis, Bright's
disease and other maladies and as
mild substitute for warm baths and
other heat applications.
The sensational prophecy has been
made that within year we shall be
lantic- and it is interesting to note
that scientific authority admits the
possibility. DR.. Sheltord Bidweli,
the British physicist, weighs the
chances. by method similar to
that which now telegraphs pictures to
photographic plates, it would he nee
cessary to pass the selenium cell
transmltter over the entire transmit
ting screen in long spiral at least
ten times every second, or the per-
sistence of vision would not combine
the successive impressions into one
view. A each passage the light var
lations of the selenium would he
transmitted from each division OF the
many thousand of the transmitter
screen to corresponding division of
the receiver screen by receiver syn
chroniZed to move exactly with the
transmitter. Such a mechanism is
not to be considered, and the only
practical plan seems to be TO provide
selenium cells and independent wires
for each division of the scene. To
produce a received image 2 inches
square, made up of units | $50 of an
inch square, would require 80, 000
elementary working parts, including
selenIum cells, luminosity -contr oil
ing devices, projecting lenses for the
receiver, and conducting wires. The
scene would be projected by 3-foot
lens upon a surface of selenium cells
s feet square,, the receiving apparatus
would occupy 1900 cubic feet, and
be = or ~ inches in diameter. A line
OF 100 miles would probably cost
ST, $50, 900.
