Marvellous Discovery of Calcutta

Research into the so-called Roentgel
Rays have experienced a new phase
DR.. Roentgen described his famous dis
covery under the name of X-the un
known formula Dr. Jagadis Chunde
Bose, NJ. A, of Cambridge, and pro
fessor of physical science, in the presi
dency college of Calcutta, now ascribei
the whole phenomena of the rays t.
electricity. DR.. Bose is now in London
whittier he has been sent by the Indiar
government, for the purpose of laying
his discovery before the British scien-
tific world The learned Calcutta
professor in discussing his work and its
results, says:
I'VE hear little and see still less
Our range of perception of sound ex-
tends through only IL octaves. There
are many notes which we cannot hear
Our range of vision is still more limit
ed. A single octave of ethereal notes
is all that is visible 10 us The lights
we see are few, but the invisible lights
are many"
Prof. Bose detects invisible lights" by
means of electric waves in the ether;
and these lights, he claims. can pierce
doors, brick walls, granite rocks,

of 81, 900 beats in a second the note pro-
duced is the limit of audibility, but q

produce light; and it is said that the
Roentgen rays Vibrate at even a higher
rate than this. To detect these in
visible rays Professor Bose has invent
ed an electric eye, consisting of sensi-
tive layer. on which the rays fall, and
which, by an electric optic nerve"
produces in the apparatus a twinling
-sensation-as the human optic nerve
does in the brain.
Professor Bose has succeeded in
ringing bells and firing pistols by
means of his invisible electric waves;
and, with the aid of special lenses
constructed with ebonite, he has trans
mitted signals for nearly a mile. Thus
ii will be possible 10 transmit signals
at sea in the densest fog.
DR.. Bose is a young Hindoo, Sc years
old. He was lately made a doctor of
science by the London university, and
IS soon 20 be made a fellow of the
ROYAL society.
'BaciIIus No. A.; This Microbe In
Used In Making Butter.
One of the most startling discoveries
of this end of the century is that mi
crobes are required to make first-cIass
butter. Bacillus No. Az is the scien-
titic term or artificial culture"
This startling microbe theory was
first advanced by a person who came
from Denmark to lecture on the art of
butter making. The theory, which was
received with scorn, is now advocated
by many scientists and many cream
cries in different parts of the country
or -f,o
state alone Qowa) IS creameries are
using the culture.
One OF the most satisfactory expert
mentS was made recently in a Connec-
tictit creamery. June butter as is well
known, is in flavor about the best pro-
duced during the year, and the effect
of bacillus No. IL upon June butter
was, therefore, especially interesting
Early in June. when the amount of
cream collected by the creamery was
very large, two watts full of cream
were collected. One of these was in
ocUlated with No. Il and the other
was uninoculated. They were then
both allowed to stand in the same
room. at the same temperature for
the same length of time, to ripen and
were subsequently churned The effect
OF No Al even here was striking. Both
lots of cream produced as was to be
expected, an excellent quality of but
ter, but No. Al had an aroma more
pronounced and more agreeable than
that of the butter made without the,
inoculation.
In both taste and odor. the butter |
made by incubation was decidedly SUI |
perior to that made without it. This |
butter was submitted for testing to a |
large number Of persons. and no one |
had the slightest hesitancy in deciding |
that No Il made the superior quality |
of butter
Experiments in improving the quail
lty and flavor of butter have been made
with over 100 different species of germs.

Inc 1irst attempt at an estimate of
bacteria in butter was made in Munich
n 1891. IT was found that there are
about 100000 in a grain. and one
pound Weighs asa grains.
