SCIENCE AND INDUSTRY.


| Composition of Old Mortar-An in
teresting and instructive fact has just
come to light. Four samples Of mortar
taken from the remains of FONDA
ton OF great antiquity which were
laid bare in Germany in March of this
year, were chemically analysed. The
striking feature in the analysis is the
percentage of lime to the sand used,
the proportion being in the four
samples S.S6, 1865, 5.33 1887 per
cent of sand respectively to one part of
lime, the sand used being very coarse
grained. The remains were supposed
to be those of a temple of the Persian
god OF light, Mithra, of about the mid
die OF the third century.
Manufacture of Cow-bells There are
four establishments in this country de-
voted exclusively to- the manufacture
of cow-bells, two being in Collinsville,
Ill. One hundred and fifty dozen are
turned out daily. and thousands of
them bangle from the necks of COWS
all over the prairies of North and
South America The manufacture of
bells is entirely differentfrom that
of other bells. Instead of being mold
ed, the metal is rolled into thin sheets.
cut into symmetrical polygons, which,
when folded, are pressed into their
well-known form. Afterbeing rivited,
they are packed in clay and brought to
a white heat. When suddenly cooled
these steel bells are found to- be not
only tempered, but beautifully bronz-
ed.
Cost of Locomotive-One man can
build an eight-wheel passenger loco
motive for a standard gauge railroad
in 1900 days; it will require 1850
days work for him to build a CONSOLE
dated ten-wheei locomotiNesfor.a a. stand
ard gauge. The average cost of the
required labor would be 81, 635, and
the cost of the necessary metal is
usually estimated at about $4,000. The
profit may be put down at another
$4,000, which would include the ex-
penses of sale and delivery. This
would make an engine. when absolute
ly ready for service and complete in
every way, worth about $685.
Prevention OF Typhoid Fever-It is
generally conceded that nothing is
more discreditable to the civilization
of the nineteenth century than the ex-
istence of typhoid fever. DR.. Edison,
of the New York health department,
in a late report, thus sums up the
logical conclusions drawn from the in
vestigations undertaken by him: '.Ty-
phoid fever never infects the atmos-
phere, it never arises de novo. The
causes of the disease, in order of their
frequency. are as follows: First, m
fected water; second, infected milk;
third, infected ice; fourth. digit Il in
lection; fifth, infected meat" DR.. Ed
son states that with the observations
of the ordinary obvious precautions
suggested by these conclusions, the
disease should not exist.
The Dangers of Carbolic Acid-Car--
bolic acid is now much less used in
surgery than formerly. Surgeons have
only gradually become acquainted with
it's dan gers. The acid may not only
cause Inflammation and gangrene, but,
also blood poisoning, and so may even,
prove fatal. 1t is useful only in the
hands of a skillful surgeon, and ought
never to be used without his advice.
The best lotion for recent injuries is
the ordinary lead lotion, which can be
bought at any chemists. The best
antid ote in carbolic acid poisoning is
soap, which should be taken Immediate
ly and repeatedly until all symptoms of
poisoning have disappeared. F..
New Architectural Effect-A build

troduced. The front of the building
has medallion formed of pressed
brick with the face Clipped off, giving
a surface that resembles rough-faced
red sandstone. The brick, while equal
in appearance to stone, will retain it's
beauty longer. as sandstone grows,
darker with time.
