SCIENTIFIC MIscELANY.

Prof. Feichtinger Of Munich has o.
served that of various kinds Of writing
and printing paper examined all those
that had been sized with resin had
more or less acid re action, while this
property did not appear in paper with
animal sizing. The acid reaction was
found to be due to free sulphuric acid,
which must impair the durability OF
paper in which it exists, aud must also
gradually destroy the black color OF
writing on the paper. Resin sized pa
per would therefore seem to be unfit
for records and other writings intended
to be lasting.
Hsrschslrs labors showed the Milky
Way 10 lie great nebula containing
1t least 100000 Of huge blazing
suns, with our sun and its attendant
planets near thu center ot the system.
This nebula il distributed in two near.
y parallel layers having the form OF
pair Of millstonss, being very thin but
extending lateral!y to distances OF
which we can form no conception.
While with on uninterrupted tra.k a
lightning express train might Pass
around our world-which seems large
to us-in less than one short month, it
could not, at its highest speed, accom-,
plish the distance to the sun in 200
years! But a beam Of light flashes
across that space in eight minutes. And
yet this beam Of light, which vastly
trAnscends in speed anything We know,
requires more than three years to trav-
81 from the nearest fixed star to the
earth, and to cross the extreme width
Of the Milky Way itself must occupy
nearly 5000 years! Even this express
60 no idea of the limits Of the visible
universe. Other nebulae than our own
must be 90 distant that tho light can
not reach our system in 100000
years!
Experiments by Koch and Welfhugel
to determine tho disinfecting power Of
bet air have led to the conclusion that
70 high temperature and so long ON
exposure are necessary to secure disin.
lection that most articles--such a.
clothing--are liable to serious damage
BY the operation.
The great red spot which has been
visible on the surface Of the planet
Jupiter for several years Is reported
to BE- growing fainter, and the early
disapperance Of this remarkable objec,
seems imminent.
In warm .blooded animals the heart,
action ceases in very few minutes
after the dcstruction Of the nervou'
centsrs or after the circulation Of tn,
blood in it, own vessels is BY any mean
arrested. Not 90 with cold bloodet
animals, however, Is the heart Of on
q them may continue to beat for man,
hours after II has been emptied o
blood and even after it has been Gu
out Of the chest. The pulsations o
the heart Of an col have been seen t
continue for six hours after separation
from the rest Of the body; Of : torpedo
for nine hours; aud Of salmon, 70
twenty four hours.
II has been ascsrtained that the frs
experiment with air balloons WAS mad
at Avignon by Montgol6cr the eide
In November, 1882. He sent up i
his room : parallslopiped Of canvas
containing forty cubic feet Of air heate
BY burning paper inside. The room
still iu existence.

It b held BY Mons. P. Dc Tchihatcl
81 that the great deserts Of Asia IN
Africa are not recently raised sea bed
but were upliftsd At remote geologic
epochs; their sands being the produ,
Of rocks disaggregated by atmospher
causes, instead Of showing . marir
origin. The Asiatic deserts are mu,
older than the Sahara.
