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

An attempt to acclimate ostriches In
South Russia has proved successful
Inc ostriehes 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
Defourteen millionths Of a millimeter, or
about seventy-five times smaller than
the smallest wave length of light. The
determination was based upon inter-
acknowledgements.
A powerful anaesthetic, which vola-
tilizes on exposure to the air, has been
invented by Polish chemist 1t is be-
lieved that bombs filled with this chem
lcal, and thrown into the ranks of an
opposing army, will in a 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 1t is not impossible
that the air near the ground, being
made to rise by being artiticially heat
ed, might tend to produce the desired
downpour of rain.
There is patented 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 as to afford a
perfectly clear view Of the writing to
an operator sitting erect and using it
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 moment when
it is desired to brush the types or insert
u fresh linking ribbon.
1t is not often that estimates are Civ
en- in years of the time that mas elapsed
since the appearance of early races of
men. Such an estimate, however has
recently been made by Mr., Jacob
Nuesch concerning the ancient inhab-
itants of Switzerland. According to
DIR. Nuesch man first appeared on
Swiss soil about 2S,0O0 years ago. He
dwelt there during 5000 years, when
great changes occurred, and for 5000
to $1,000 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 q recent lectur,
by Prof. William Crookes on 'Dia
monds." Prof. Crookes made spe
cial study of the diamond mines o.
South Africa, and his conclusion is tina
the gems found there have been crys
tallized out of molten iron containing
carbon in solution, and at sutficien
depth below the surface to give grea
pressure: but this is doing on larg
scale what Moissan, the French chem
ist. has succeeded in doing on SINAI
scale. Moisson makes microscopic dia
. monds by dissolving carbon in iron
and causing the crystals to form unde
pressure. The chief difference appear
to be in size and capacity of the labor
: atory, in which regard nature has
vast advantage.
Z DR.. Won Liebig of the University G
Munich calls attention, in Science,
some of the curious effects of raretie
and of condensed air on human re-
piration. On high mountains SON
persons experience distressing "shor
: ness of breath" one result of which
that they are unable to whistle. Pr
cisely the same effect is sometime
produced by the condensed air in cal
sons and diving-bells. Laborers worl
ing in compressed air frequently fin

are Increased as long as the atmo
pheric pressure is not more than do
BILE that of ordinary air; but beyor
that point unpleasant effects are e
perienced after the men have left Il
working shafts and returned into Il
