SCIENTIFIC MISCELLANY.

Among the dangerous citizens late
ly recognized Is tho microbe carrier,
who, immune himself and probably
unconscious of the misery he is caus-
ing, spreads broadcast the deadly
germs of diphtherla, typhoid fever
dysentery, plague, cholera, Influenza
spinal meningitis, and many other
diseases. The pathogenic microbes
simply survive in the body, in many
cases. long after the disease has pass
ed away, Referring to this newly con-
sidered source of danger. DR.. Simon
Flexner states that a. years after an
attack of typhoid fever the typhoid
bacilli were still being eliminated
plague bacilli have been present In
the sputum T6 days after recovery
from plague pneumonia; and influenza
hacilli have been found IN the sputum
one year after an attack of influenza.
The discovery suggests new views of
pears to be one of adaptive change
on the part of the parasite as well
as on that of the host.
The qualities of seed used by plant
ers may depend upon conditions not
yet sufficiently considered. Late OBJ
servations in Switzerland and Austria
have shown that plants grown from
the seed of spruces of high eleva-
ton, such as 5000 feet make much
slower progress than plants from seed
OF trees of lower elevation, like 1000
feet. Other characters. such as tho
weight of the seed, length of grow
ing period, and possibly tendency to
disease, seem to vary with the stu
alton of the seed trees.

BY reconstructing the old domestic
hand loom for use with power,
weaver near Chemnitz has opened the
way for q considerable return to tex
tile manufacture in the home, not
only in Saxony but in other localities
where electricity provides cheap pow

is built almost entirely of wood. 1t

This household machine is very quiet
in operation, sells at $50 or about
one-fourth of the price of an iron
mechanical loom, and the cost Of
weaving in the early experiments has
been less than half of that with the
factory loom. 1t Is to be adapted
coon for weaving manifold thread in
stead of the single thread of the first
model.
The usual method of using solar
heat has been to concentrate the
suns rays by mirrors, but in the
simpler apparatus with which Frank
Tacoma, Pa, the direct rays have
been made to heat a boiler of black
ened pipe-coils enclosed in q shallow
box with a double glass top. An air
space OF one inch between the two
layers of glass forms a Jacket pre-
venting escape of heat by radiation
Water in the pipes generated steam
with pressure of Is pounds. which
was made TO drive an engine. and by
employing ether a pressure of 80
pounds was reached In warm cli-
mates a good working pressure is ex-
pected from water, thus solving the
perpleSing power problem of tropical
lands.
The old suspicion that tobacco af-
fects the heart and even plays some
part In arterlosclerosis--the dreaded
thickening of the arterial walls SO
common in human decay-has been
confirmed by Zebrowski Russian
physician. Rabbits inoculated with
tobacco extract, with nicotine, and
with adrenalin. all showed marked
thickening and dilation OF the walls
OF the aorta, or main artery.
