The thermophile fabrics of c. Herr
gott, of Valdoie, France, introduced
novel method OF applying warmth,
and are expected to do much for
domestic electric heating. The
fabrics are a combination of textile
and conductive threads, the latter
being made of any required size and
combining with any textile materials
When woven, the electTothermic wires
are hidden, many electrothermic
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 no
danger of fire or other accident. The
temperature may range from 70 de-
grees to 90 degrees +. for carpets up
to $50 degrees to 300 degrees for hot
air baths, and the possible applica-
tions are many, including use for
footwarmers and articles of clothing
and furniture, drying apparatus, baby
incubators and numerous hospital
appliances and most purposes requir-
ing constant, moderate heat.
The new glass making process of
Fourcault, of Belgium, combines
some of the advantages of plate glass,
which is finished by rolling fiat upon
smooth table, and of ordinary
window-glass, which is blown in
large bubbles and cooled on fiat
surface. In the new method, the
molten material is drawn upward
through a system OF rollers rising in
a tier of seventeen pairs. The thick
ness is regulated by the distance
apart of the rollers in the pairs, and
the glass produced is perfectly fiat
and beautifully polished.
After az evening shower, lily, the
Crinum augustum, shows a striped
bud four inches long, Is fully
blossomed in few minutes, and
within an hour the petals have curved
over an arc of or inches. Kineto-
scopic pictures, to show the growth
of flowers, are suggested.
In recent experiments the bouquet
and characteristics of the famous
wines of Bordeaux, Burgundy and the
Kline have been tIansplanted by
means of germs from the cask dregs
nt hn al 4.
brand of germs is placed for keeping
in jelly-like mixture of Japanese
isingIass and fruitiuice. in which it
soon forms a colony. When required
tor use, some of the germs may be
added to tube of stelilized fruit
juice, and in two or three days the
juice will be in full fermentation
and lively etfervescence-a duplicate
of the old wine.
a naturalist relates that the appear
ance of perch, breamand crayfish in
newly-cut dams near the Macquarie
river, in New South Wales, was at
first a perplexing mystery, the fishes
even being noticed alter the first rains
in the dams, and for some years
spontaneous generation was regarded
as the only possible explanation.
Then came a simple, and credible
solution of the problem III a Sydney
biologists discovery of half-hatched
fish ova on the breast and wings of
a wild duck.
Sulphur is being tried in Germany
as wood preservative. 1t is applied
in molten form, and as it hardens it
completely fills the pores. At moder-
ate temperatures it is unaffected by
water, weak or strong acids, or
alkaline solutions. A disadvantage is
that the sulphur melts at lis degrees
f., and this makes the treated wood
unfit for places exposed to consider
able 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 abso-
lutely tasteless, according to new
German process, by causing them, in
liquid form, to be absoI bed by
natural agar-agar, then graduating
or puIveriZing, and drying.
The incubation of plants with
nutritive and curative substances Is
new field of great promise. The
need of tonic was suggested by the
exhausted appearance of certain fruit
trees, and sulphate of iron was in
jected into the sap, with especially
favorable results in chlorosis of the
vine. CoIored injections have been
used by Monryetski, Russian to
show something of the penetration of
the liquid into the cell. The c!Icula-
ton proved to be confined to the
young layers, never entering the old
wood, but the liquid rose to the top
of the tree aud passed three or four
feet into the root. The best method
of injection seemed to be through a
hole in the neck of the root. In
disease OF stone fruits weak solutions
of oxalie acid, creosote, cit1ic acid
and salioylio acid have been tried,
and the last named had particularly
good effect. 1t is expected that
suitable drugs will have influence in
producing variations and new plants
as we'll as in supplying food and
medicine.
