making artificial marble, regarding
which so much has been said. Th1
claims set forth that limestone, or othe
like substance including alabaster stone
may be given the appearance and uni
form hardness throughout of natura
marble in its various colors by the ap
plication of moist heat or heat in the
form of steam, in combination with s
bath of alum and water, or with various
baths composed of various chemicals
and coloring matter.
SOLIDIFICATION OF PETROLEUM.-A
very curious effect is produced on the
oils of petroleum. even those of the
least gravity, by the addition of pow
dered soapwort (saf onaria), an
herbaceous plant of the order of Cargo
phylloceg. On digesting the powder
with water and mixing it with the oil
the latter forms g very thick mucilage,
so that the vessel in which the expert
ment is made can be turned upside
down without spilling the contents
What is still more singular, is, that if a
few drops of carbolic acid be added, and
the mucilage be shaken, it becomes in a
few minutes perfectly limpid again
honnonger.

A CORRESPONDENT sends the New
York Tribune an account of lady who
was relieved from the most excruciating
agony OF pain caused by a complication
OF disorders by having her bed moved
from the wall and placed on heavy
glass salt cellars, thus insulating it en-
tirely. The electric currents were there
by prevented from flowing away from
the body, and until her death, which
occurred some weeks after this insula-
ton, she was entirely free from pain.
1t is said that in many diseases where
there is acute pain, as in rheumatism,
like happy results will follow insula-
ton. The bed clothing should be so
adjusted as to touch only the bedstead
or objects uponit.
ACCORDING to Professor jaeger of
Leipsic, the proportion of water in the
tissues and the liquids of the body is
one of the chief factors in liability to
illness. Any treatment, therefore, that
aids the discharge of water from the
system by the lungs, skin, etc., is con-
sidered favorable. The promotion of
perspiration, both sensible and insensi-
BILE, by keeping the skin perfectly clean,
the wearing of woolen clothing, vigor-
GUS gymnastic exercise, the use of hot
drinks, thorough ventilation of sitting
and bed rooms for the elimination Of
moist air, are all of much Importance
According to the Professor, the specific
gravity of a living being is good cri-
terion of his strength of constitution,
power OF resistance to causes of illness,
and power of work.
A CORRESPONDENT writing from Paris
states that well attested cure of HYDRO
phobia is just now occupying some at
tention in the medical world. The
discovery is due to the experiment of
two Russian physicians, Drs. Schmidt
and Ledeben. A little girl aged II was
bitten on the hand by mad dog. The
wound, after being cauterized, healed
in few days, but hydrophobia set in
fortnight afterward. The physicians
thereupon made the little patient inhale
three cubic feet of oxygen. By this
means III the course of an hour and a
half all the symptoms disappeared and
the child remained calm. Two days
afterward the malady returned in all its
distressing characteristics difficulty in
breathing and swallowing, and tonic
commissions. A fresh inhalation of
oxygen was tried, and at the end of 45
minutes the attack subsidized never to
return
A RECENT examination of French
black silks showed that they were heav-
lily adulterated. The weight of dye in
American silks is about Il per cent,
but the French silks showed a weight of
from 80 to 50 per cent. The principal
article used in weighing is iron. The
silk is repeatedly inserted in solution
of nitrate of iron. 1t then receives a
blue tint from prussiate of potash, fol-
lowed by several baths in gambler, and
a treatment with acetate of iron. 1t is
then made brieht by logwood and soap.
To make the silk soft, little oil and
soda are added, while to max, it stiff
and rustling an acid is used. The
Z" wearing shiny is caused by the ac-
ton of the soap and alkali, which de.
velop, under friction, sort of grease.
The cracking of silk is owing to its in
ability to carry the great load of ma
terial used in the dyeing.
No one in st. Petersburg is allowed to

shortly before that hour, the old man
