The theFmophile fabrics Of @. Herrgott Of
WALDORF, France, introduce novel method Of
applying warmth. and are expected to do much
for domestic electric heating. The fabrics are
combination of textile and conductive threads.
the latter being made Of any required size and
combining with any textile materials. When
woven the electro-fhermic wires are hidden,
many electro-thermfc wefts enter into each
circuit, and the circuits are joined by collector
wires Of which one pole Is placed In each selvage
of the fabric. There Is danger of fire or other
accident. The temperature may range from 7O'
to o5o f. for carpets up tn 1902 to 1902 for hotair
baths, and the possible applications are many,
including use for foot-warmers and articles of
clothing and furniture. drying apparatus, baby
incubators and numerous hospital appliances
and most purposes requiring constant moder-
ate heat.

plate glass, which is finished by rolling fat upon

which Is blown in large bubbles and cooled on
fat surface. In the new method. the molten
material is drawn upward through a system of
rollers raising in tier of seventeen pairs. The
thickness IL regulated by the distance apart of
the rollers in the pairs. and the glass produced
is perfectly fiat and beautifully polished.

Sulphur is being tried 10 Germany as wood
preservative. 1t is applied in molten form, and
as 1t hardens it completely fills the pores. At
moderate temperatures it is unaffected by
water. weak or strong acids, or alkaline solu-
lions. disadvantage is that the sulphur melts
ct 115o f., and this makes the treated wood unfit
for PLACES exposed to considerable heat. The
best wood for use with this process is poplar,
the trials of oak and pine having been much
less satisfactory.
Medicines are made almost absolutely taste

ise. The need Of a tonic was suggested by the
exhausted appearance of certain fruit trees,
and sulphate of iron was injected into the sap,
with especially favorable results in chlorosis of
the vine. Colored injections have been used
by Monryetski, Russian, to show something
of the penetrotion of the liquid into the cell.
The circulation proved to be confined to the
young layers, never entering the old wood, but
the liquid rose to the top of the tree and passed
three or four feet into the root. The best
method of injection seemed to be through hole
in the neck of the root. In disease of stone
fruits weak solutions of oxalic acid, creosote,
cftric acid and salicylic acid have been tried,
and the last named had particularly good effect.

Our much-neRlected sense of smell can be put
to important uses. When we'll developed, it
may serve in medical diagnosis, and some
English physicians have pointed out lately that
diabetes. enteric fever, acute rheumatism,
plague, abdominal fistula, undressed cancers,
erysipelas in some cases. gangrene of the lung
pyaemia, septic mouth, bleeding hemorrhoids
and undressed varicose ulcers are among the
disorders that emit characteristic orders. and
that can be recognized by smell alone. Care is
necessary, however, as the physician, after in
nuena or the taking of alcohol himself, may
fancy his own odor to be that of his patient.

The electric target of Canadian officer, Lieut..
Col. G.. A. Peters. is being tested by English
rifemen. The target itself is a bullet-proof
plate OF chrome steel, and the impact of the
bullet on this drives back one or more of set
OF steel hammers, thus closing an electric cir
cult. by which the exact spot hit is recorded on
an indicator plate at the firing point. The sys-
tenn insures accuracy. saves much time, and
needs no attendant.
