DR.. HARRIMoRE estimates THAI a cubic
inch of tartar upon the teeth contains
250,OOO.O00 animalcule, and he suggests
to those so afflicted the liberal use OF
tooth brushes and floss silk, .s
THE observatory for the study OF the
sun, which the Emperor Napoleon had
erected ut ST. Cloud for M. Jannsen,
was one of the first buildings which the
Prussian army wholly destroyed.
Photography is now applied in medi-
cine to the delineation of wounds and
their changes during treatment. A
splendid collection of photographs OF
this kind belongs to the Royal Medico-
Chirurgical Society, London.
IT HAS been discovered that New
Hampshire has LAO towering plants
and 4l0 of the lower orders-In all,
1850. On the White Mountain tops,
Arctic plants found nowhere else in
this country are numerous. .....
As AN evidence of the thoroughness
with which the botany of Great Britain
has been worked up, it is stated in
Nature that no new indigenous plant
has been added to the flora of that
country during the past year.
A SMALL species of lizard has recently
been found in Terra del Fuego. This is
an interesting fact, as Mr. Darwin has
commented on the absence of reptilian
life in that country, although expressing
an opinion that it may yet be found to
exist
Mr.. GEORGE MIvART, who has written
the abest book published in opposition
to the Darwinian theory, says, in a re
cent article in Nature, that science con
vinces him that monkey and mush-
room differ less from each other than do
a monkey and man.
julius KRAFFUB, Prussian engineer,
has invented machine which will
manufacture ice without chemicals,
merely by compression and expulsion OF
air The specimen machine, now at
New York, can turn out two tons OF ice
day, and the capacity can be increased
to twenty-five tons more.
A BEAUTIFUL photograph of the Plei-
ades-that group of stars popularity
known as the Seven Sisters-has lately
been taken by Mr.. Rutherford. We re-
greet to learn that over-work has so
affected the health of this distinguished
amateur astronomer as to compel him to
seek rest abroad for time.
ANOTHER new meat. preserving pro
cess, said to be very successful, is
described in the Moniteur Scientfque. It
consists in the immersion of the meat
in solution Of perfectly pure carbolic
acid in water. Not only raw meat, but
eggs, fish and vegetables can be pre-
served by the same method.
TOBACCO grown in q cold climate is
stronger than that grown in a mild one,
and similar statement is true with re-
gard to celery. So it appears from an
article in the Journal of the Pharmaceu-
teal Society, where it is maintained
that in the vigorous vegetation of cold
climates, as compared with that of warm
regions, the active principles of plants
are more concentrated in the leaves.
IT is a long way from Hecla, in Ice
land, to Etna, in sunny Sicily. Yet
scientific men tell us that there is little
doubt that these two volcanoes are con-
nected by tunnel or subterranean
passage Of communication. There are
good reasons for this belief. The great
internal earth-pulse beats simultaneous
ly in each. Etna is never disquieted,
but Hecla never show symptoms of
eruption without some throbbings in
Etna. Ancient and gigantic twins are
they, standing for ages widely separated,
but holding mysterious communication
through an unexplained labyrinth, q
fiery artery, through which their hot
blood flows and mingles.
IT seems only little while since, on
the Odd of April, the planet Mercury
reached its greatest elongation, and was
distinctly seen in the western sky, as q
brilliant evening star. The swift little
planet has not been idle, but has since
travelled more than a hundred million
miles in its orbit, and having reached its
greatest western elongation on the OPP
posite side of the sun, was this morning
shining brightly as morning star, about
two hours before sunrise. More than
half of Mercury's short year has been
completed since we watched its glowing
light in the fading twilight; and more
than two entire Mercurial seasons have
passed since our spring, then half COM
pleted, has ripened into summer. Be
fore our summer wanes, this swiftest
and brightest member of our planetary
brotherhood will complete another
oscillation on the celestial pathway, and
reappear as evening star.-ProUidence
