SCIENCE AND INDUSTRY.

Composition of Old Mortar-An in
teresting and instructive fact has just
come to light. Four samples of mortor
taken from the remains of founda-
ton of great antiquity which were
laid bare in Germany in March of this
year, were chemically analysed. The
strik ing feature in the analysis is the
percentage of lime to the sand used,
the proportion being in the four
samples $3.50, 1866. 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 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,
LII. One hundred and fifty dozen are
turned out daily, and thousands OF
them dangle from the necks of COWS
all over the prairies of North and
South America. The manufacture OF
cow bells is entirely different from 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
weltknown form. After being rivited,
they ass packed in clay and brought to
white Neat. When suddenly cooled
these steel bells are found to be not
only tempered, but beautifully bronx
ed.
Cost of a Locomotive-Onem man can
build all eight-wheel passenger loco
motive for a standard gauge railroad
in 1900 days; it will require 1850
days. work for him to build consoli-
dated ten-wheei locomotive for a stand
ard gauge. The average cost OF the
required labor would be $4,635, 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 IS, 635.
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 late report, thus sums up the
logical conclusions drawn from the in.
designations 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, In
fected water; second, infected milk
third, infected ice; fourth, digit Il in.
lection; fifth, infected meat" DIR. 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
its dangers. The acid may not only
cause Inflammation and gangrene, bu
also blood poisoning, and so may even
prove fatal. 1t is useful only in the
hands of skillful surgeon, and ough
never to be used without his advice
The best lotion for recent injuries i:
the ordinary lead lotion, which can bt
bought at any chemists. The bes
antidote in carbolic acid poisoning il
soap, which should be taken immediate
ly and repeatedly until all symptoms O
poisoning have disappeared.
New Architectural Etfect-A build
ing has just been completed in Colum.
bus, Ohio, in which novel and beauti'
full architectural feature has been in
troduced. The front of the building
has medallion formed of pressed
brick with the face Clipped off, giving
surface that resembles rough-faceG
red sandstone. The brick, while equal
in appearance to stone, will retain it's
beauty longer, as sandstone grows
darker with time.
