The only known examples of paint
ings of men by prehistoric cave de-
coratois have just been discovered by
Rene Jeaunel in the portel Grottc, a
cave Uf Louhens, in Ariege, France,
where NouIet had already found
Quaternary remains and human bones.
a bout forty sketches in black or red
only one in both colors- adorn the
cave as frescoes, and two represent
men of primitive tyre, while the
others show bison. bears and horses.
OF the human figures, one has long
head with retreating forehead, while
the other shows remarkably ape like
pose, with rounded back and arms
pendent in front. There is a crouch
ing boar, but the horses are mostly
galloping and poorly drawn, although
the forequarters of "A horse are quite
skillfully figured in black upon one
of the darkest walls of the cavern.
Soap is not regarded as dangerous,
but German physician records two
cases of fatal poisoning by it, and
warning is given that the material
should be kept out Of reach of the
insane and children. Each of the
victims both insane persons-ate a
cake of ordinary soap, death follow
ing in one case in an hour and IN the
other case in two days. Analysis
showed no distinctly poisonous in
gredient, and the fatal effects could
be attributed only to the material as
soap. Heart action was rapidly
diminished before death.
A remarkable secret writing of the
prisons has been brought to notice in
Germany by Prof. Gross. A well
moistened sheet of writing paper is
laid on hard smooth surface under
a dry sheet, a hard point being then
used to write on the latter, which is
at once destroyed. The writing,
which disappears from the bottom
sheet on gradually drying, reappears
distinctly as often as the sheet is
moistened.
Continuing the experiments of M.
Leduc, who has shown how electrical
sleep may be produced, Miss l..
Robinovitch. M. d., of New York,
has made a special study of local
anaesthesia produced by intermittent
low tension electric currents of con-
stant direction and of artificial cleo
trical respiration as a means of re-
suscitating the apparently dead
Local anaesthesia, easily produced in
the forearm by a current of 20 volts,
is often employed in her Practice
In rabbits and other small animals, a
current of or volts sent through
the body causes peaceful sleep,
which may last for hours, but a sud
denly broken current of 50 volts or so

continuing for a few minutes to half
all hour, while the action of II TO 10
volts is quite different, resulting in
real electrOcution in half minute to
one minute. DR.. RabinovItch has
found, however, that the electr ocuted
animal may be brought back to life
by intermittent electrical impulses in
the same rhythm as respiration. Ibis
gives artificial respiration, speedily
followed by resuscitation, and prompt
application may revive and save the
lives of persons whose heart beats have
ceased after accidental shocks up to
1000 volts The same method will
prove valuable in resuscitating pa
tients who have succumbed to chloro-
form or ether.
a material equal to the best Port
land cement is now claimed from
blast-furnace Stag as a product of the
Cowper Coles process. The Stag is
taken while still molten and raised
to greater heat by means of an cleo
trio resistance furnace, the necessary
amount of chalk being added, and
then certain reactions are brought
about by electrolysis. High grade
cement is thus obtained at very low
cost.
The new serum with which DR..
Bertrand of Antwerp, claims to cure
pneumonia, is applied in four or five
injections aggregating not more than
half cnbic inch,-no other curative
serum taking effect in such small
doses. Serious symptoms disappeared |
in less than 36 hours, even in adj
vanced stages where danger was in
