Tea-drinking is an acquired habit and NJ Jules
Rudolph expresses the belief that it would not
be difcult to transfer our liking for Chinese tea
TO any one Of the various infusions having the
same eject in aiding digestion and stimulating
the nervous system. Some Of these infusions Of
leaves and flowers have been known to us as
medicines. Camomile, veronica, sage, ambrosia.
horsemint and wintergreen are among the local
II well known Of many common plants yielding
agreeable feas, and Paraguay tea and false tea are
already much used in South America. NJ Ru-
d0lph looks upon Roman camomile as an espe-
ciaily promising tea substitute. He has found
the unknown tea Of the tarragon to be very
pleasant, ana it is useful in stomach weakness.

A stereoscopic star chart is the successful
novelty Of 7. 3. Heath. the English astronomer
The stars IN given section Of the heavens are
drawn from two points Of view that are sup
posed TO be twenty-six light years apart, and
under large stereoscope the double view gives
rough but very instructive impression of the
stars floating in space at an approximation to
their relative distances. instead of as points
against the dark background of the sky. This
result is most interesting one.

The recent classification at the British Patent
Once shows that cooking Is the popular subject
Of invention. having been the subject Of 1915
British patents IN l8 years, or an average Of 70
year. Umbrellas brought out 1.i57 inventions
and hats All. Invention tends to run in grooves,
1895 and 1897 rejecting the enormous develop
ment in cycles, while motor vehicle inventions
have doubled since 1900.

The rare popularity known as haemophily. or
"bleeding sickness" has been brought to notice
anew by DR.. Boehme, German physician. 1t
continues for generation after generation in
certain families. and is characterized by an ex-
traordinary tendency to hemorrhage, making
the extraction of q tooth a dangerous operation.
while even pin-prick may lead to severe or
fatal bleeding. The cause seems to exist in an
unexplained failure Of the blood to coagulate
ike normal blood. The disease has been studied
in more than sixty European families. and in the
Mampel family has been followed for more than
century. Johan Peter Mampel and wife were
not "bleeders." OF their eleven children three
members Of these and subsequent generations
Of the family most singular law Of heredity is
deduced. This law is-that while the disease is
practically confined to males it is never trans
mitted by these males to their sons. but only by
the women-who are normal-to their sons.

The new petroleum fuel reported from Swift
zerland is in the form of briquettes containing
four parts of petroleum to one part of secret
material. At fifteen cents per gallon for oil the
cost Of each briquette was about tx cents, but
on large scale would be much less. Four bril-
Quettes under boiler having heating surface
Of 400 square feet ignted the coal in fifteen min
utes, the briQuettes themselves burning forty
I'VE minutes. Among the claims made for the
fuel is that it may he kept in piles fifty feet high
without breaking or crumbling, escape of liquid,
loss Of weight. or risk of explosion or spontane-
GUS combustion.
Enormous swarms of butterflies move along
the Amazon and other South American rivers.
d. Goeldi, of Para, Brazil, finds that detached
masses make detours to visit trees in bloom. but
does not explain the general migration. One
suggestion is that the great flights are made up
Of females seeking mimosas as place of egg
laying.
The repulsive action of light is shown in very
pretty experiment. An hour-gIass shaped glass
vessel is partly filled with very fine and light
lycopodium spore. and the air is then pumped
out to as high vacuum as is practicable. The
spore falls down through the orifce Of this hour
glass in the usual way. AS the light dust jet
falls an intense beam Of light focused on it just
below the hole spreads it out into a spray, the
lighter particles being repealed most. On COM
paratiyely heavy material, like sand, the light
beam could have no effect.

A specimen Of the powerful electric bells now
being made by London firm for railway use has
gong lex inches in diameter and weighing go
pounds. and the complete bell weighs about $50
pounds The iron clapper is two inches In diam
eter. making from 100 to $50 strokes per minute.
The acting parts are entirely enclosed in a
water-tight cast-iron box, the pull rod for NOV
ing the clapper coming through a packed gland.
The current needed three-fourths ampere at IS
volts--is supplied by IL ordinary dry cells.
New smoke-burning appliances continue to
use up considerable share Of the worlds in
ventive energy. The promising idea of Bel
gian chemist consists In drawing the smoke out
OF the chimney by an aspirator and passing it
through filter Of coke saturated with petro-
leum. The filter collects the SCOT. while the
gases passing through are made combustible by
the enriching with petroleum vapor. There is no
loss, as the coke Of the filler is an excellent fuel

For twenty years fishes of many varieties have
been kept in aQuaria by +. Davis, of London. and
his observations have convinced him-contrary
to common belief-that fishes sleep though only
In darkness. Artificial light awakens them. He
finds also that fishes have their play or sports,
like other creatures.
