To Nicolas Leblaucs great discovery
Of the method of extracting soda from
common salt Mons. Dumas traces the
vast development of the worlds chemi-
cal industries during the last hundred
years. OF carbonate Of soda, prepared
by Leblanc's process it is estimated that
the present annual consumption in Europe
and America is from 700,0G0,000 to
sO0,OOO,OOO Kilograms (77l,6oo to $751;
800 tons.) Yet the name Of the discov-
CT had nearly been forgotten until the
recent action of people of his native town
-Isoudum-in proposing to erect
monument to his memory
A medical writer states that eggs con
tains fifteen and onc-fourth per cent. OF
carbon and two per cent. Of nitrogen
As food for sustaining the active forces
Of the body, the. value of one pound of
eggs is to the value OF one pound of lean
beef as | ,5S4 to 800. As flesh produce
or, a pound of eggs is about equal to
pound of beef.
According to DR.. II. Cradle, the pro
geny of one of the microscopic, beings
known as bacteria may, with plenty Of
food, amount to over 5000, 900 within
twenty-four hours.
In experiments at the kill Agricultur-
q Station, Germany, Prof. A. Emmer-
ling has found that ammonia produces
only slight effect when used to manure
clay soil, ana on sandy soils the results
we're very unfavorable. On black soils,
rich in hamus, the application Of ammonia
yielded good returns.
ut is now some years ago" says the
Lancet, ''since DR.. Henry MacCormac
promulgated the theory that the vera
causa Of phthisis was the respiration Of
pre-breathed air. According to this view
healthy man constantly exposed to an
impure atmosphere, rendered so by his
own breathing or that of other individuals,
is physically certain to become tubercu-
lous. Such notion has been entertained
BY many high authorities, but, 80 far as
We know, always rejected after due con-
sideration.'
With the aid of powerful steam siren,
Mems. Il. Panchon has shown that the
highest notes audible to the human ear
have Y 900 vibrations per minute. After
the limit Of hearing is passed, the vibra-
tons still agitate the sensitive fame Of a
.gas-jct. To obtain notes far above the
upper limit of human hearing Mr., Fran
els Gallon has devised whistle blown
By hydrogen gas, aud he has made such
an instrument Ola inches long and O,O4
in diameter which gives sound Of 3l2,-
600 vibrations per second. Mr.. Cotton y
whistle was constructed with the object
Of testing the hearing power Of insects,
which, as is well known, have very acute
ears.
Humboldt placed the number of exist
ing volcanoes at 407, of which 225 had
been active within century. Later cs-
Inmates credit the Indian Archipelago
alone with over 900.
Prof. Fischer, Of Munich, has lately
obtained from coal-tar white crystalline
powder which greatly resembles quluine
in is action on the human organism. The
range Of its action does not seem to be
thoroughly understood yet, but its effect
in rapidly reducing fever-heat is pro-
nounced remarkable, and it is believed
that this property alone will render it
valuable medical agent. 1t produces less
Inconvenience to the stomach than qui-
nine. Observation has not yet shown,
however, that it possesses the tonic and
restorative influence for which quiuine is
20 often administered. The new substance
Is called "kairin," and its manufacture
has been commenced in Germany. What
ever may be its virtues, the cost Of its
production--said to be over 81 an ounce
will probably cause it to be introduced
slowly.
Mons. Pasteur believes that cholera is
produced by minute organisms of some
kind, but the germs have never vet been
discovered. He has recommended the
French Government to send special
mission to Egypt to study the generation
