most curious is the tact that the ntltiDe
point OF the alloy is Usually lower loau
tat OF auy of its components. Woods
sltoy, To- instance, which consists of lead
tin, cadmium and bismuth, melts al
above 1862 F., while the lowest melting
point OF any OF the metals separately il
that Of tin, 44ee. 1t has always been sup
posed that this alloy could only be formed
st comparatively nigh temperature, but
Mr.. William Hsllock has recently shown
that when The several metals are mixed
together 10 filings, and exposed for
twenty four hours to the heat of an or
binary water bath (2l2o), the alloy is
produced, and the mass becomes fluid,
andthst the previous fusion CT either
constituent is unnecessary.
The bridge across the classic Oxus, on
the line OF the Russian Trsnscsspfan
Railway, is 1900 feet longer than The
Brooklyn bridge. The entire railroad is
remarkable piece CT engineering. II
was considered impossible to maintain 8
railroad through the shifting sands
CT the Kara-kum desert. But Gen.
eral AnnepBeff, by covering parts
OF his roadway with clay, by placing
IN his embellishments layers of the branches
OF desert shrub and by cultiva.ing along
parts OF the route many thousands OF
desert plants, the roots of which retain
the shnd, has thus far maintained his
ro.d-bed without deterioration. The
problem OF water supply Was solved by
bringing water in pipes from the noun
tains that skirt 200 miles CT the route,
slso by canals from the Murghab, while
artesian wells are the source of supply
between Merv snd the Oxus. In region
that ls destitute Of fuel and where the
cold is at times intense petroleum has
been utilized TO drive the locomotive an1
TO heat the sixty railroad stations aIong
the wey.
A German journal gives !the following
process for making blottiIg paper able to
give copies OF letters: Soak four parts
of The best clear glue in mixture of five
parts OF pure wster ard three parts Of
ammonia liquor until the glue is thorough
ly sof ened. Warm it till the glue is dis
solved, and add three parts Of graduated
sugar and eight parts of glycerine, stir
ring the whole well, and letting 1t come
to the boiling point. While the mixture
is hot paint it with broad brush on
clean white blottng paper until the latter
is thoroughly soaked and thin coating
remains on the surface. Let it dry for
two or three days, and 1t will
be ready for use. The writing or
sketch to be copied is done with the usual
sniline ink on writing paper. Before
transferring it to blotting psper wet the
latter with q sponge or brush and clean
water, and allow it to stand for one or
two minutes. Place the written side on
the blottipg paper and press cut the air
bubbles. After few moments OF gentle
pressure remove the written matter. A
number OF copies eau then be made after
The manner Of the "grapS" processes from
the bIottipg psper. When the impress
siors grow faint dampen the surfsee Of
the blotting paper sgsin.-[ CasseI's
