Is is the old story. The world refused
him bread while living; now it gives him
monument.
A specimen of vegetable wool is on ex-
hibition at Amsterdam. II comes from
Java. When il is freed from its leathery
covering and the seeds, through a very
simple process, IT is worth between 10
and IL cents a pound.
A correspondent Of one of the medic
al journals says that the application of
a strong solution of chronic acid three
or four times day, by means ofa cam
els hair pencil, is the best and easiest
method Of removing warts.
A simple and efficient device for clean.
ing sinks has recently been patented by
Mr.. r. C. Turner, of Brooklyn, n. Y. 1t
consists of suitable brush or scraper for
collecting the refuse In the sink, COM
bined with shovel for scooping it up.
A patent has recently been issued to
Mr.. +. s. Gullick, of Bolivar, N. Y, for
an improved stove-pipe holder, which
consists of an extensible hanger and an
extensible hoop, contrived in simple
arrangement for suspending stove pipes
from the ceiling in better way than by
the wire suspenders commonly EN-.
ployed.
'Thc best quality Of charcoal" says
the Enquirer, "is made from oak, maple,
beech and chestnut. Wood will furnish,
when properly charged, about 20 per
cent. Of coal A bushel of coal from pine
weighs about 20 pounds. A bushel of
coal from hard wood weighs 80 pounds.
About 100 parts of oak make % of char
coal; the same quantity of red pine 22l0,
and of white pine 49,"
An improvement in table casters for
holding condiment bottles is the subject
of patent by Mr.. Orin F. Bacon, of Taun-
ton, Mass, which provides an anti.fric-
ton bushing. or collar, for the hslder, or
for the standard, by which the wear on
the holder IN the pintle and the conse-
quent rattlins of the caster when turn
ed are obviated, and the durability of
the caster is greatly extended.
The French Ministry of Commerce is
engaged in drawing up the particulars of
the patents for inventions granted in
France since the foundation of the pres
ent republic. The work so far is CON-
plete up to the end of 1878. During the
eight years prior to the end of 1876 there
were nearly mean annual average of
= Tar -. 10 In,
the succeeding years tie number of APP
plications has considerably increased.
Mrs. Augusta Netzner, of New York
City, has patented a very strong suspen-
der end. This suspender end is provid-
ed with cord between the two strands
of each strap, which cord has its lower
end secured at the lower end of the
strap, and its upper end secured to the
upper part of the strap. The cord is
thus made to bear the greater part of the
strain. and the ends thus rendered ex-
ceedingly durable.
A Yokohoma paper states that John
Milne, whose researches on earthquakes,
as explained by him to the British asso-
citation at Southampton, have excited
great mi crest in scientific circles, and
who has since returned to his duties in
Japan, has applied to the Japanese au-
thorities to establish an observatory, in
order that he may be able to thoroughly
investigate underground phenomena.
He has sent the authorities long trea-
tise upon the earthquakes of Japan.
From the latest reports regarding the
cholera in Egypt which became epidem.
ic last summer it appears that the germs
of the disease are always present in the
Nile Delta and only wait the circunr-
stances which go to their development to
make pestilence at any time. The dis
ease does not seem to be imported. 1t
has an abiding place in the country.
Now that Egypt is so closely connected
with the great distributing centres of the
commerce of the world the final report
of the Scientific Commissioners will be
looked for with interest and given an
attention worthy of the subject.
Paper gas-pipes are made by passing
an endless strip of hemp paper, the
width of which equals the length of the
tube, through bath of melted asphalt,
and then rolling it tightly and smoothly
on core to give the required diameter.
When:the numpcr of layers this rolled is
sufficient TO afford .he desired thickness
the tube is strongly compressed, the out
side sprinkled with fine sand and the
whole cooled in water. When cold the
core is drawn out and the inside served
with a water-proofing composition. In
addition being absolutely tight and
smooth, and much cheaper than iron,
these pipes have great strength, for
when the sides are scarcely three-ffths
of an inch thick they will Withstand a
pressure of more than 10 atmospheres.
If buried underground they will not be
broken by settlement, nor when vio-
lently shaken or Jared. The material
being bad conductor of heat, the pipes
do not readily freeze.
The sun has been, during the past
summer, in a state great excitement as
to sun-spots, and the surface still shows
considerable number. About the lst
of August there were several instances
of remarkable eruptions OF prominence
in connection with spots at the edge of
the suns disk. Thollon, in France, OBJ
served one in which the l474 line, which
characterizes the spectrum of the corona.
was bent and distorted in such way as
TO show that the coronal matter itself
was implicated in the Disturbance
most unusual thing. Generally this line
remains bright. smooth and keen as ra-
pier, even when all the other lines in
the neighborhood-lines ofiron, magne-
stun, calcium. hydrogen and what not
