French Rronautic authorities have
given the name ";pronef." or aviation
apparatus, to a flying machine that Is
heavier than the air. The varieties In

and driven by one or several propellers;
CD the Rroplane, chiefly sustained by
one or more flat or curved surfaces, ana
(3) the orthopter or mechanial bird,
sustained and propelled by beating
wings.
growing evil reported by DR.. Aba
SZtankay among the SlOvaks OF Upper
Hungary is the habitual use of cam
phor internally. For fourteen years he
has persistently questioned buyers OF
the drug, and he concludes that at
least twenty-five per cent of the large
and increasing amount sold Is used by
the camphOr-eaters. An increase in
epilepsy seems to be result Of this In
dulgence
Flaming arc lights have now become
an established feature Of downtown
Chicago streets. They are new, COM
paratively, for such commercial pur-
poses, but their principle has long been
known. The flaming arcs thus far
shown in this country produce light
yellow, red or vivid white light ac-
cording to the carbons used The ad-
dition Of the salts of fiuoride, bromide
and iodide Of lime give the light the
yellow tint, while other salts Of lime
give the flame a red color.
Leprosy is increasing in both North
and South America. Colombia, where
there were only 400 lepers forty years
ago, is said to have 10000 now, and
many find their way into the United
States. Such medical authority as
DR.. Ashmead, who was formerly chief
medical adviser to the government of
Japan, says the increase Is alarming.
When leprosy Is brought into new
country it takes fifty years for the
seeds to take root. and 1t becomes epi-
demic after some 200 years. 1t has been
shown that mosquitoes are active in
transferring the baclli Of leprosy.
The first section of the railway
across the Andes between Chile and
Argentina has been officially inaugu-
rated, and work has been begun on the
highest part Of the line, where. at an
altitude exceeding 10000 feet, great
tunnels are to be constructed. The
largest Of these tunnels will have
length of 3,405 yards, not far from
equally divided between the Chilean
and Argentlnian sections. With the use
of that portion of the line already COM
pleted, the journey between Valparaiso
and Buenos Ayres will be shortened
several hours.
An Important use has been found for
the Cooper Hewitt mercury vapor lamp
In scientific Investigation. In optical
In the laboratory 1t Is
often important to have at command
light Formerly the
mercury arc light was employed for
this purpose, but after being used for
short time the efficiency Of this source
Of light seriously falls Off. 1t has been
found, however, that the Cooper
Hewitt lamp gives the same monochro-
matte light, with very fine rays, so that
it is admirably suited for the study OF
phenomena. and 1t pos
sesses the great advantage OF being
steady and trustworthy In It's output.
Moreover being a commercial appara-
tus, it Is easily obtained, and can be
used at a comparatively small expense.
