1t has been found that larger amount
of ammonia exists ir the atmosphere
when an epidemic of yellow fever is at
its height than al other times, decreasing
as the disease lessons.
While it has long been known that
fishes return each year to about the same
place to spawn, recent observations of
their habits show that they go up the
left hand side of the stream and come
down on the opposite side.
Herr Fisher thinks the extensive
planting of forests in the countries of
North Africa would prove much more
efectual in restoring those desert regions
to their ancient fertility than the pro-
posed inland sea in Algeria,
Accurate measurements made by Rus.
sian authorities have proved that the lev
el of the Baltic sea is nearly two feet
higher at Constandt than at Reval, and
that the height decreases regularly from
north to south. This conclusion is full
ly supported by Prussian measurements
at Meme! and at Kiel.
The researches of DIR. Bollinser show
that the milk of cows suffering from tu-
bercular disease may communicate the
affection to human beings. AS five per
cent. of COWS advanced in life suffer
from this disease, the doctor believes the
danger to be considerable. Boiling the
milk is not u safeguard.
In a recent lecture in London, Prof.
Graham advised all who must smoke 10.
do so on the German plan-tbat is, with
out expeetoration. This heoohles easy
when the tobacco used is thoroughly
dried, as then only comparatively
small qantity of creosote and the larry
products of combustion collect in the
mouth. Saliva performs an important
part in digestive processes, and its sup
ply should be husbanded.
A Norwegian, Ernest Frolich, thinks
he has found in the Indian rice of Amer
lean swamps living proof of the truth
of Snorre Sturlson's history of Self
Rricsson's visits to this country nearly
nine hundred years ago. Tie voyagers
reported finding in Vinland not only an
abundance Of wild grapes but also a kind
of grain which Mr.. Frolich believes TO
have been the Indian rice, or wild rye.
1t grows plentifully in swampy locali-
ties, as did the gram described by Erics-
son.
Mr. Hannay's diamonds are produced
by the freeing of carbon from a HYDRO
carbon-by means of the affinity of the
hydrogen for certain metals at a high
temperature-in presence of a stable
nitrogen compound, under the conditions
of red heat and great pressure. The
action Of nitrogen compound causes the
carbon to crystalline The pressure re-
quired is enormous, and forms the great
difficulty Of manufacturing carbon crys-
tails by this process. Tubes, constructed
on the gun-barrel principle, of only half
an inch bore and an external diameter of
fnur inches, are torn open in nine cases
out Of ten.
The electric light is hot without its
dangers Some time ago bit of red-hot
carbon dropped from one of the LAMPS
of the British Museum TO table usual
ly occupied by readers; and a repetition
of the accident few days later set FIRE to
some loose paper on a table in the same
room. 1t is conceivable that a single
spark might do irretrievabIe damage to
some unique manuscript OF other liter
airy treasure. To intercept such stray
pieces of carbon as may fall in the future,
transparent saucers have been hung I'M
