Like other modern occupations,
wireless telegraphy has brought
special disorders to man. In the
campaign In Morocco, the wireless
telegraph operators of the "Des-
cates' of the French Navy have been
pretty steadily employed, and DIR.
Z. Bellile, the surgeon on board re-
ports that the Hertziau waves have
developed various maladieF among
these men. The eyes we're much
affected, cases of slight conjuncti-
Wits, keratitis and leukoma being
common. This was due to the very
powerful action of the ultra violet
rays, and the wearing of yellow or
orange glasses was advised. Another
allment set up was eczema, Of which
there we're two cases-one of the
wrist and one of the eyelid-both
difficult to cure. A particularly un-
comfortable case was that of an
official who had worked the wireless
telegraph several years, but who
suffered from painful palpitation of
the heart after using the sending in
struments for any considerable time.
DIR. Bellile is inclined to attribute
also to wireless telegraphy much of
the nervous arrangements now be-
coming rather common among naval
men.
The making of ice goblets, which
cool beverages as they are served,
has been so perfected by Ii. ID. Z.
Huizer, at his simmer resort factory
near The Hague, that 100 per hour
can be made with one horse power,
only small refrigerating machine
being needed to supply the cold
brine. The mold is of special metal,
with a core of porcelain, and after
pouring in the water the whole is
submerged in the brine at 40 degrees
below zero for six minutes, then
passed for a moment to special
heater, when the goblet is pushed out
and caught in paper holder. Each
goblet contains half pint. 1t can
be filed only once. but will hold the
beverage half an hour in hot weather.
Every metal is believed by Grutin,
German chemist, to have it's
peculiar odor, which he regards as a
gaseous transfoI nation product. He
has made some of the odors percep
tible for few moments at intervals
by heating the metals to 122 degrees

Cork tissue, or 'tissue-liege, :"
the novel waterproof fabric now be-
ing made in France, is ordinary cloth
with lining of cork only 1-250 of an
inch thick, and is a substitute for
rubber cloth that is claimed to be
free from most of the defects of that
material. Before Eeing sliced into
thin layers, the cork is freed from
its resinous matter, thus booming
very flexible. The thin sheets are
then pressed into the outer cloth,
forming a perfect lining for cotton,
wool. silk, ramie, felt or leather and
the resin freeing treatment has made
the cork so plant that it may be
folded without breaking. The outer
cloth or other material is unchanged
in appearance. A garment from the
cork lined fabric is soft and comfor-
table IS perfectly proof against water,
does not deteriorate like rubber cloth,
is very light, and has no odor. When
desired, another lining-of cloth
may be used to cover the cork layer.
TO zee Mars and other heavenly
bodies better is an attempt of greater
pronise than efforts to telegraph to
worlds of which we know SO little.
The earth's atmosphere varies greatly
"a clearness, and, while American
astronomers have established several
observatories in very favorable locali-
ties, it appears that just the best
spot for a great international obser.

effort at looking outward can be
made-has not yet been determined.
