tural Gardens, has but little faith in the
statements as to the suitability and value
OF the EUCALYPTUS globulusr in swampy
and marshv districts. The results OF his
experiments with the tree confirm the I'M
favorable results that have also been OBJ
tanned with it in Italy.
1t is said that the sand used in the man.
utacture of mirrors is now used by a Paris
company to make white bricks and
blocks, said not to be injured by fr0sts,
rain. etc, and TO be very light. the specific
gravity being only l.5O to 1S5 of clay
bricks. The sand is first strongly pressed
by hydraulic power, and then baked in
ovens at very high temperture. The
bricks are almost pure silica.
BY experiment Prot StOrer has found
that scantily fed mice will sometimes eat
daily One-thIrd OF their weight of ordina-
ry putty. When carbonate OF lead,
baryta, zinc or oxide Of zinc or bride of
zinc was mixed with the putty the mice
were able still 10 eat small quantities
with impunity, those pigments seeming to
lose their usual poisonous quality. Putty
containing no whiting was untouched, or
eaten very reluctantly.
A tunnel. measuring about 5000 feet
long and constructed at least nine CEN
turtles before the Christian era, has just
been discovered by the Governor Of the
Island of SamOs. Herodotus mentions
this tunnel, which served for providing
the old seaport with drinking water. 1t
Is completely preserved, and contains
water tubes of about 10 inches in dame
ter, each one provided with lateral aper-
ture for cleansing purposes. The tunnel
is not quite straight.
A Belfast Ireland) genius has invent

and breaches stuffed with straw. 1t is a

tached. The wind makes the fans go
round and they jingle the bells. greatly to
the annoyance of the crows. But water
motor ought to be attached to the machine
as provision against calm.
How to produce painless death in the
lower animals has been carefully studied
by DR.. W. B. Richardson. He seems at
last to have succeeded in securing euth-
anasia for them, The animals to be de-
stroyed are placed in a chamber. into
which is forced current OF carbOnic OK
ide passing at so deg. Fahrenheit over a
mixture OF chlOrOform and carbon bsul-
phide Extinction of life is soon effected
in the chamber by the lethal nature of its
atmosphere so brought about.
Some learned physicians now prescribe
nitro-glycerine as a stimulant in place OF
brandy. It's said that two drops Of
per cent. solution is equivalent to an
ounce OF brandy, and it creates no I'M
natural craving. This last defect will
probably prevent its ever becoming popu-
lar as an intoXicant. Were it not for this
it would be splendid liquor to smuggle
in candy drops. The nitrO-glycerine to-
pers would have to be careful about tum-
bling in the streets, as the charge might
go of at any time.
Now the Atlantic is traversed I'm less
than week, but Mr.. William Pearce
looks confidently forward to the time
when he will be able to produce vessels to
make the journey in four days. The pres
ent great increase IN speed has not been
| accomplished by finer lines or proportions
OF the ships, but entirely by the immense
engines that force the vessels through the
water. The three cylinder engine has con-
trlbuted the chief capacity in solving the
great problem OF increasing speed and
lesseDing cost Of fuel.
From experimental measurements Of
the temperature of the body during acts
OF motion the following conclusions have
/ been reached by French observer: That
the lowest temperature in man. following
a period of rest. is 9S.4deg.; that the tenn
! peTature rises under the influence of an
ascending effort to 1905 deg, and under
the influence of a descending effort to
| 1908 deg; shat it increases after any eX-
| ertion, but more after an ascending than
a descending one; and that the chemical
actions of the organisms are augmented
after every movement.
A process, which is in general use in
! France, by which two pieces of horn can
| be perfectly Joined together, is as follows
The pieces of horn are first heated before
/ a ore. and the edges where they are to be
| Joined carefully scraped, until they fit to-
| gether exactly; the workman then takes a
| pair of pincers, previously heated quite
hot, and after moistening the edges which
are to be Joined, presses them together
firmly and quickly. If the operation is
skillfully performed, a perfect joint will
result; and after the edges have been
dressed smooth with fine file, and pol
ished with tripoli and water, it will be
hard to tell where the two pieces are join
