With few exceptions, Australian
trees are fonni to flourish as we'll
in Californi as in their native coun-
try. Conversely, it is expected that
the native vege atom of Califor-
MA can be successfully grown in

succeed i'll the one country are likely
to do SO in tine other.
/ A Frenchman has invented q rub.
Der attachment to DO applied to the
corks of bottles from which liquids
may be forced in drops through
glass tube or pipette. This will be
great convenience for nurses and
attendants upon the sick who often

A Hungarian chemist has lately
shown some surprising experiments
in Paris with a new light-giving SUBJ
stance, which burns with so little
heat that it's flame will not set fire
to handkerchief, carpet or other
fabric with which it may come in
contact. A person may hold the
burning liquid in his hand without
injury. This new illuminating fluid
is prepared from petroleum.
An invention which must prove of
much importance in architecture
and sculpture has recently been
made By DR.. Gehring of Landshut,
Bavaria. BY means of an enamel
ing liquid he claims to be able to
render any kind of cement or stone
harder than granite, and gives it the
appearance of any other mineral de-
sired. The enamel may also be ap-
piled to metal, and is said to effec-
tually preserve it from rust.
The american Builder says the &C.
emulation of SCOT may be prevented
by putting a quantity of salt into
the mortar with which the inter-
courses of brick are to be laid.
Then there will never be any accum-
ulation of SCOT in that chimney.
The philosophy of it is thus stated:
The salt in that portion of the NOR
tar which is exposed absorbs mois-
ture from the atmosphere every
damp day. The SCOT thus becom-
ing damp, falls into the fireplace.
The laborers in the st. Gothard
tunnel have suffered from q myster-
ious disease that long baffled all
physicians; but an italian physician,
DIR. Giaccone, has now traced it,
with the aid of microscopic investi-
cation, to parasitic worms that are
engendered by the underground at
mosphere and lodge in the intes-
tines of meu working in it. A
Swiss physician, DR.. Sondsregge,
has supplemented this discovery
by advising a method of expelling
the parasites. The two doctors are
hailed in Switzerland as benefactors
of their race.
1t was recently remarked by Prof.
Maudsley that one striking feature
observed by medical men in cases of
hallucination is that tho patients
cannot be convinced that the objects
they see, the sounds they hear and
the smells they perceive have no real
existence, and that the sensations
received are the result of an excited
state of their nerves. Hallucination
often extends to but one sense, the
person affected being otherwise in q
perfectly normal condition. 1t may
arise either from an idea on which
the mind has dwelt closely, or from
excitement of the sensory nerves.
1t is said that Newton. Hunter,
and some others of equal eminence,
could, at will, picture forms to
themselves until they appeared to
be realities.
