MICROBES DESTROYED BY STEAM
The experiments OF steam disinfection,
recently tried ia Jacksonville, have proved
that the stcammg process is thoroughly
enicacious in destroying microbes IN gen
eral, aud also the yellow fever microbes.
Active germs placed by Dr. Glbier IN
gelatine filed glass tube gerninated, show
ing unmistakable life and activity. Microbes
subjected 10 the steaming process. though
for only ten inmates. and under very in-
perfect conditions, We're afterward sub
jected TO the same cultivation, but re
manned entirely inert.
NEPTCSE's sATELIT-s.
NJ Tisserand has presented report 70
the Paris Academy Of Sciences concerning
some remarkable observations OF the sat
elites of the planet Neptune, which WAS dis
covered in lS47 The angle which the plane
of the orbit of this satellite made az that
date with the ecliptic was about thirty ce-
grees. Dut this angle has now increased by
at least six degrees. Tho satellite moves
around its principal in an opposite direction
20 that usually followed bv other satellites,
so that a question might be raised whether
in the course Of time this variation III the
inclination OF the plane Of its orbit might
not end IN It's movement around its prin-
cipal becoming normal. NJ Tlsserand
showed that this variation of inclination
was due 10 the oblate or hattened condition
of Neptune AT It's poles, and that il win com
plete its limit within n period Of five hun
dred years, at the end OF which tune it VIII
be as it was IN 1S47.
VARIOUS LOCATIONS OF THE CAPITAL

located at different times at the following
places: At Philadelphia from September

KEEN SENSE or PRESSURE.
The relative sensibiilty 10 pressure Of dif-
.ereut parts Of the body is asoeriaincd by
placing weights Of the same size, but Of dlf-
fcrent amounts, upon the skin. BY this
means it has been found that the parts
which have the keenest sense Of pressure
are generally those in which senslbillty 10
touch IS most developed. Tie saallcs,
weight which can be perceived is three one
hundreGths Of a grain, and this - recoc-
nised by the skin OF the forehead, the TEN
pics. the back Of the hand and the forearm
The tips OF the ngcrs can perceive a
weight OF thrcc-tair. .ieths Of n grain, the
chin and the nose one Of three lourtns
Of a grain, while the finger mails do not
! notice one weighing less than fifteen grains.
Considerable pressure may be cxcrtcd
without its being perceived, II II is uniform.
Thus when the hand IS plunged into mer-
( curry the increased pressure is only at the
/ line corresponding with the surface OF the
fluid.
