posed the shadows appear on the lu-
'nous circle. They are not optical
shadows as is proven by the fact that all
o ors oo]ects do not give them. They
s'e produced in general only by con-
u"c'ors and semi-conductors of electri
Guy, ana insulating bodies give little or
10 shadow. A glass rod with one end
u'aue conducting by heat gives a par
tlal shadow, which gradually disap-
pears on cooling.
Croll has calculated that the amount Of
neat conveyed from the equatorial re-
sions northward in the Atlantic by the
uoit stream is equivalent to 77,479, ESQ.,
ooo'oo'oOO,o0o foot-pounds of energy
per day, which is equal to all the heat
received by 1,56o,935 square miles of
surface at the equator, and more heat
than Is conveyed by all the aerial cur
rents.
The object-glass for the Lick Obser-
vatory telescope is to be three feet in
diameter, and, il successful, will be the
most powerful instrument of the kind
ever made. About three years will be
required to finish the telescope.
Many people, says the Electrician,
nave observed that blow or other lar
ring shock will sometimes dispel pain :;
out the importance of mechanical vi
oratlons as an anodyne is now engaging
the serious attention of physicians. For
some years past DR.. Mortimer Granville
mas been endeavoring to find a good
means of mitigating the pangs Of neu-
ralgia by recurring series of shocks
administered to the skin over the affec-
ted part, and he has constructed an 40
paratus for the purpose which has been
employed successfully on various occa-
slons. M. Boudet of Paris, has howey-
er, quite recently developed the sub
Ject still further, and applied the ordi-
nary dlapason, or tuning fork, to the
purpose in question. He was led to do
this by the experiments of NJ. Vigou-
roux, who provoked contractions in
bysterical patients, and subdued the
pains of nervous cripple by causing
the sonorous waves from a vibrating
tuning fork and sounding board to i'm
pinge upon his limbs. NJ. Boudet i'm
proves upon this treatment by bringing
the vibrator into actual contact with
the surface of the body. He does this
by tuning fork kept in constant vi
bration through the attraction and re-
pulsion of an electro magnet, in which
an electric current flows, and rod hav-
ing one end connected to the fork and
the other applied over the nerve. So
efficacious does it appear to be that GER
tain kinds of neuralgia, especially in
the less deap-seated nerves, are charm
ed away after few minutes use. The
subject is yet in it's infancy, but it is
profile that other kinds of physical suf-
fering may be sootbed by the vibratory
influence, and it is not unlikely that
complete anaesthesia, similar to that
produced by chloroform, may result
Hom tremors of the Uranium, for when
the fork is applied to the walls of the
skull, a swimming of the head followed
by desire to sleep, is frequently in
duced. There are good reasons for be-
lieviug chloroform acts through me-
chanical disturbance of the sensory
nerves.
That grounding mentioned by the
Bossier Banner, which came out of his
hole in February, took look at the
weather, and went back, drawing his
hole in after him, and announced to his
old lady that winter would last six
weeks longer, was about correct. The
month Of March has been the coolest
within our recollection. There were
two freezes last week; last Sunday
there was heavy frost and on We'd
nesday and Thursday of this week we
had two more freezes. But nothing
green seems to he hurt by the cold :;
even tender grrden vegetables stand it.
This is owing to the fact that the wealth
er has been continuously cold, and
there is but little sap in plants.
A young lady, named Miss Martha
Freeman, we believe, was murdered
near Lake Charles few days ago. She
had been to town and started home,
some two miles below, and after being
missed for several days, her body was
found in the lake. with neck and jaw
broken evidently by blows of q club.
Blood was found On the lake shore near
by.
AS usual, the woods are full of wild
turkeys, no one brings us one, and we
haven't time to go hunting.-CLake
Charles Echo.
And when you have time to go hunt
ing, and do go hunting, do you always
bring a wild turkey7 1t is difficult
bird to bring.
