The loca, pronunciation Of geograph-

1t is held by Mons. P. do Tchihat-
chef that The great deserts of Asia and
Africa arc not Isosntly raised sea-bpds,
but were urlii;cd at remote geographical
epochs; their sands being the product of
rocks disaggregated by atmospheric
causes, instead of showing a marine cra
igin. The Asiatic deserts are much older
than the Sahara.

be matter of doubt that humanized
lymph should be entirely abandoned in

Herr Crsner; has made some expert
ments on the putrition.6 of man in his
sixty-fourth year who had practiced yeee-
tarianism since be was eleven. He finds
that strictly vegetable diet may main
tain the bodily and mental functions,
but it only suffices to prolong life when
the quantity of vegetables is reduced by
introduction of animal albumen7 in the
form of milk and eggs. He recommer ds

In warm -blooded animals tie hearts
action ceases in verysfew minutes after
the destruction of the nervous centres or
after the circulation of the. blood in its
own vessels is by any means fsrrested. /.
Not so with cold-blooded animals, how
ever, as the heart of one of them NAV
continue to beat for mary hours after it
has been etnptied of blood and even after
it has been cut out of the chest. Tho
pulsations of the heart of an eel have
been seen to continue for six hours after
separation from the rest of the body; of
a atorpedo, for nine hours; and of salmon
for twenty-four hours.
Prof. Feichtinger, of Munich, has
observed that of various kinds of writing
and printing paper Examined, all ti'oss
that had been sized with resin had
more or less acid reaction, while this
property:did not. appear in paper with
animal sizing. The acid reaction was
found to DO due to free sulphuric geld,
which. must impair the durability of
paper in which it exists, and must also
gradually! destroy the black color of
writing, on the paper i3Resin-sized paper
would therefore seem TO be unfit for rec

Herschell's labors, showed the Milky
Way to be a great neoula containing at
least fifty millions OF huge blazing suns,
with our sun and its attendant planets
near the centre of the system. This
nebula is distributed in two nearly paral-
lei layers having tho form ofa pair of
millstones, being very thin but extending
laterally to distances of which we can
form no conception. While With IA un-
interrupted track lightning express
train might pass around our world
which seems large to us-in less than
one short month, it could not at its high
est speoa accomplish the distance to the.
sun in two hundred yearsl But beam of
light flashes across that space in eli BIT
minutes. Aud yet this beam of light,
which vastly trPnscends in speed any
thing we know, requires more than three
years to travel from the nearest fixed
star to the earth, aud to cross the ex-
treme width Of the Milky WsY i,self must
occupy nearly three thousand yearsl
Even this expresses no idea of the limits
of the visible universe. Other nebulas
than our own are visible in space, and if
as lates as our own must be so distant
that the light cannot reach our system in
one million years!
