cut increase OF temperature, and produces
a liquid capable OF generating with the aid
Of zinc and carbon an electric current. 1t

lieht upon colors printed on cotton. They
conclude that the electric light bleaches
cOlOring matters; the cOlOred rays OF sun
light and OF the electric light both being
ofiicacous, though in different degrees.
The action OF light, solar or electric, is
recognized, whether the colors are eX-
posed to or protected from the air. and the
activity OF the rays increases in the follow
ing order: Yellow. blue, green, orange,
violet, red.
VI. 4. Liyache has aScertained that an
ordinary drying oil containing lead dries
in tGCnty-foUr hours, but similar oil con-
taining manganese dries under the same
conuIiious in from five TO six hours. Cop
per. zinc, cobalt iron, chrome, &c.. pro-
long The time OF drying = thirty-siX TO
foIty-cght hours. Ia practice Livache
takes an ordinary lead oil, adds TO it dry
manganese suphate in fine powder, and
agiiatcs the mixture ior some time in the
cold. The manganese is entirely Sub,titu-
ted for the lead, and the oil obtained freed
from GrCgs by simple decautation possesses
an extreme drying power.
4 process for rendering textiles water
tight and ncombustible has been invented
by N. Dumas. The fabric Is list passed
through solution containing 7.S per cent.
OF gelatiDe heated to 400. Alter remaining
in the solution few minutes the fabric is
pressed between rollers TO remove the sur
plus liquid, and afterward allowed 10 dry
partially in the open air. Ii Is then per-
mitted 10 steep for short time in a cold
81 solution OF alum, and Is then taken out,
exposed 10 The air for OH hour, washed in
cold water, and finally dried. lis claimed
that goods thus treated are quite permeable
to air and lose neither their elasticity nor
soitness.
