CURIOUS. USEFUL AND SCIENTIFIC.

Water used in wool. washing yields 4 80
per cent Of a very dry potassium, which can
DO recovered, as NJ. DelattIe has shown, at g
considerable profit.
Struve upholds DR.. Biedent's suggestion
that only cream should be used for the earli-
est ncurishment Of young children brought
up by hand, Sc the digestibility of any milk
is inverely rs the quantity of caseine which
remains in the skim-milk.
Drs. Mitchell and Rsichert find that the
fuli.grown lizard will bite and cause wcund
that may prove fatal Unlike thst Of other
reptiles Its saliva is alkaline, rot acid. A
little injected into pigeon caused the death
Of the bird (which Was long, iat and plump
IN less than nine minutes.
The technical experts connected With the
Austrian Government are reported to have
succes sfuily applied portable electric lamps
70 the illumination of the revolving towers
which are being constructed in the oltworks
of the hsrbor of Pols, the chief station of the
Austrian Navy. This circumstance puts an
end TO the difficulty which has hitherto exist
I'd Of lighting such towers, as they contain
large pieces Of ordinance in a very limited
space.
More than 20 years ago HennesSy called
attention to the superiority of water for the
absorption and diffusion Of heat derived from
the sun. His conclusions have gradually
commanded increasing support. Mr.. w.
Henel in q recent publication has maintained
that the difference IN temperature between
the northern ard southern hemispheres Is
very slight, and that the southern hemis-
phere, which has the larger mass Of water,
has the higher temperature of the two.
A very exhaustive series OF researches on
entiscptics and the volatile properties Of
putt efaction have been made by Nj. Gust I'VE
! ia Bon. All OF bis conclusions are of & -est
scieatifc interest, but they hardly stmi. Of
ineligible or useful pyecis. The expert
nents explain, however, the so-cslled acci-
dents which have attended tie exhaustion
of bodies buried for a long time, and prove
ttat the atmosphere of cemeteries may, con-
trsry to Whist has been stated. Judging from
its freedom from microbes, be very danger
cue. The volatile alkaloids engendersd by
the action Of microbes upon certain organic
eubstsnces pla :, beyond dOabs, an i npor-
,snt role in many affections. Avoid walk

You know that the theory of gases sni
vspors, now generally accepted, is toss they
consist of molecular or atomic proiecsiies
endowed, in short, with q motion not OF vi
brstior, but oftranslstioD. When two MOLE
cules elssb, or when a single molecule strikes
| against its bOundry, the fret effect Is to de-
form the molecule, by moving It's atoms ous
! Of their pieces. But gifted as they ara with
/ enormous rssiliency, the atoms immediately
recover their positions, and continue TO
1 culver in C, nsequence of the shock. Held
| tightly by the force of affinity, they resem Die
string stretched 10 almost infinite tension,
and therefore capable of generating tremors
of a meet infinite rspidity. What we call
the heat of gas is made up OF these two
moiions-the fight Of the molecules through
! space, and the quivering oe their constituent
atoms. Thus does the eye Of science pierce
to Whist Newton called Athe more secre. end
! noble works Of nature" and make US st home
amid the mysteries of world lying in all
probability vastly farther beyond the range
# the microscope than the power of the mi
crofcoTe, at its maximum, lies beyond that
