DIR. Constantine FahlberE recently de.
scribed 10 the German Technical Society
a new substance which he estimates 60
possess from twenty to thirty times the
sweetness Of cane sugar To chemists
the new body will be known as "anhy.

Mons. foussaint has shown expert
mentally the serious dangers Of eating
meat nearly raw az is now 50 generally
done. II the meat is unsound, the germs
Of disease must pass into the system
| The most frequent and dangerous malady
with which animals slaughtered for food
are affected is consumption, and even ii
tho animal ia only slightly diseased per.
sons eating the uneooked meat are liable
to infection. The raw juice pressed
| slightly from COWS lung was used to
inoculate rabbits and young pigs, and all
the subjects died in q short time from
the disease. The experiment was re.
peated with portion Of the juice which
had been partially cooked, and the result
was the same. Only thorough cooking
was found to efectually destroy all the
infectious germs.
During total eclipse Of its surface the
moon assumes copper red color. which
gradually fades away as the eclipse pro-
crosses. Mr.. w Mattieu Williams &C.
counts for this curious phenomenon BY
supposing that the Illuminated portion Of
the lunar surface, lacking the protection
OF an atmosphere, must be made red hot
by tho suns rays. Only a thin layer Of
the moons substance Is so heated, and |
when the suns rays are Withdrawn it |
rapidly coOls, causing the fading away Of |
the red color when in the shadow Of the |
earth. II this hypothesis IS correct, Mr.. |
Williams believes that the surface tenn |
perature OF the bright side Of the moon |
must he about GOO. OF course the dark |
side must be intensely cold, 50 quickly /
does the heat pass into space after the
sun disappears. On the whole the moon /
must be an uncomfortable world.
Recent evidences seem to indicate that
under certain conditions, vegetable mat
ter may be converted into coal in q much
less period than many biologists have
believed TO be necessary. At least an
approach 70 guch conversion has been
IN some OF the mines os the
Upper Hartz. in Germany, where some
Of the timbers originally used a. supports
have heen transformed into what appears
to be genuine Ignite, brown coal. The
time occupied by the process cannot, IL Is
believed, have extended beyond four CEN
turies-a very brief period compared /
with that usually assigned to coal forrna-
tons.
1t has been shown by Prof. Loornis
that more rain falls in the eastern than
in the same latitude on the western side
Df continents. This Is true everywhere
except in the higher ATTITUDES. Thus the
average rainfall at San Francisco Is only
from half to third as great in quantity
- III the east Of Pennsylvania; and the
Iame or even more striking difference
nay be found by comparing Morocco
With the Chinese coast, and the west
with the east coasts OF South AfrIca.
Australia and South America.
Mr.. Jacob Reese is credited with hay-
ng expressed the belief that If it were
possible to produce lameless conbus-
ion the intensity and quantity Of heat
obtained from given amount 0: fuel
would be greatly increased thereby Mr..
Thomas Fletcher Of Warrington, Eng
and, has succeeded in producing com
,ustIon without flame, and lately gave at
)wens College striking practical Illus
ration Of Mr. Reese's theory. He di.
ected the fame Of a simple eas blowpipe
Ipon q three inch ball Of iron wire for a |
ew seconds, and then blow out the
lame. The heat rapidly increased and ,
he wire quickly melted and ran into ,
rops. He even succeeded in fusing re-
FACTORY fire clay, the intensity Of heat .
'eing much greater than ever before Oh
aimed with the fuel used. Even in the
ark the burning Of the gas was shown ;
0 be entirely invisible. 1t appears that
he flame really indicates an imperfect /
ombustion
Prof. German See has called the atten- !
ion OF the Paris Academy OF Medicine to 1
new medicinal alEaloid said to resemble
igitalis in its action but having none of
he objectionable properties OF that drug. ]
he new substance is called convallairne,
nd is obtained from the lily OF the val !
ey. 1t acts powerfully on the heart, $
overs the pulse very decidedly. The !
liant itself is said to have been long en-
'loyed by Russian peasants for dropsical
Elections.
