The swallow has a larger mouth, In
proportion to its size, than any other
bird. He needs a scoop-net mouth,
for he does all his feeding on the wing.
Place a snake on a smooth surface,
as a polished table, and it makes no
Roadway, because it finds no resistance
on the smooth surface 70 aid 1t In push

An attempt to acclimate ostriches In
South Russia has proved successful.
The ostriches born in Russia are much
less sensitive to cold than the imported
ones, and their plumes are equally
good.
The wave length of Roentgen rays,
according to Prometheus, has been as
certained by DR.. Fromm of Munich to
be fourteen millionths of millimeter, or
about seventy-five times smaller than
the smallest wave length of light The
determination was based upon inter-
/ ference-phenomena.
A powerful anaesthetic, which vola-
tilizes on exposure to the air, has been
invented by Polish chemist. 1t is be-
lieved that bombs filed with this chem
ical, and thrown into the ranks of an
opposing army, will in few moments
make the foe utterly helpless.
Condensation is the result of chilling
the air. The ascent of the lower strata
of the atmosphere into the higher re-
gions and the consequent expansion
and loss of heat is the most probable
cause of rain, and it is not impossible
that the air near the ground, being
made to rise by being artficially heat
downpour of rain.
There is patented a useful addition
to the typewriter in the shape of pair
Of small mirrors, measuring each nine
and one-half inches by three and one
half inches, SO mounted 9s to afford
perfectly clear view of the writing 10
an operator sitting erect and using ii
table height. The mirrors can be at
tached to any machine, and do not IN
terfere with any of its uses, while they
can be turned aside in a moment when
1t is desired to brush the types or insert
a fresh mixing ribbon.
1t is not often that estimates are Civ
Ell in years of the time that has elapsed
since the appearance of early races Of
I men. Such an estimate, however, has
recently been made by Mr.. Jacob
Nuesch concerning the ancient inhab-
ltants of Switzerland. According TO
DIR. Nuesch man first appeared on
Swiss soil about $4,000 years ago. He
dwelt there during 5000 years, when
great changes occurred, and for 5000
to l., 600 years man seems TO have been
absent. He reappeared at the begin
ming of the Lake Dwellers' period,
which lasted 1000 years, and closed
1000 years ago with the Introduction
of bronze.
Much attention in scientific circles
has been attracted by a recent lecture
/ by Prof William Crookes on 'Dia-
monds." Prof. Crookes made a spe-
cial study of the damond-mines of
1 South Africa, and his conclusion is that
the gems found there have been crys-
/ tallized out of molten iron containing
| carbon in solution. and ut sufficient
/ depth below the surface to give great
| pressure; but this Is doing on large
scale what Moissan, the French chem
list, has succeeded in doing on a small
scale. Moisson makes microscopic dia-
monds by dissolving carbon in iron,
and causing the crystals to form under
pressure. The chief difference appears
TO be in size and capacity of the labor
atory, in which regard nature has
vast advantage.
| DIR. Won Liebig of the University of
Munich calls attention, In Science, to
some of the curious effects of rarefied
and of condensed air on human res
! piration. On high mountains some
persons experience distressing short
ness of breath" one result of which is
that they are unable TO whistle. Pre-
csely the same effect is sometimes
produced by the condensed air in Gals
sons and diving-bells. Laborers work
ing in compressed air frequently find,
however, that their powers of exertion
are increased as long as the atmos-
pheric pressure is not more than dou-
BILE that of ordinary air; but beyond
that point unpleasant effects are ex-
perienced after the men have left the
working shafts and returned into the
open air. on the other hand high at
mospheric pressure in the case of per-
sons not doing manual labor has been
found to act as mental stimulus, in
creasing the impulse to talk.
