The city Of Paris has this year
opened scientific information bureau
at the Sorbonne, and the inquiries al
ready reach as many as twenty In sim
gle days While special consideration
Is given to scientific matters In Paris
and France, foreign subjects Of French
interest receive attention.
The recent excitement in the cotton
market has served to attract atben-
ton to the possibilities Of cotton rails
Ing in various places where that indus
try has not yet been developed. From
Bogota, for instance, comes the in
formation that in some parts of Colon
bia cotton can be seen growing wild
on land that has never been titled, and
the newspapers of that country are
trying to create sentiment in favor
of the cultivation Of cotton there.
A remarkable instance Of apparent
mimicry in Ceylon has been brought
to notice by DIR. A. Wiley. a fish,
commonly known as the sea-bat, strik-
mgly resembles decayed leaf, and a
recent observer reports pursuing one
Of these fishes with a small net when
the creature suddenly disappeared, and
the pursuer saw only a yellow jak leaf

the objects themselves would be seen
with short Photographic objective.
This conveys to the eye very natural
effect, suggesting unconsciOusly cor
rect perception Of relief and dis
tances.
The Eteam-heating and electric
lighting combination now being tested
by Dresden promises to open new
era in municipal economy. A huge
central station OF the Saxon govern
ment contains ten generators, produc-
ing over $1,000 pounds Of steam per
hour, and this is distributed through
: street mains to the Royal Opera
House, the Picture Gallery, the Twin
ger Museum, the Royal Palace and
other buildings. After the morning
heating, little steam is needed to keep
J up the temperature, 80 that most Of
the supply can be used for general
ing electricity, for lighting and Other
> purposes during the latter part Of The
day.

Ical instruction, there are seven gDe

OF training locksmiths and black

! are admitted such students only a
3 have completed course IN one Of thl
+ other six schools, and the curriculum
q is highly advanced, covering physics
i chemistry and electricity, with par
