Chemical analysis alone is no longer
the guide to the quality of iron and steer;
In the new autobiography a Poilsnsu
and etched sample is examined under tne
microscope, when it is found to be mace
up of various minute particles, OF which
Mr.. A. P. Head, the British engineer
gives the following as the chief: !. Fer
rite. or pure iron, soft, ductile and con-
ductiye. 2. Cementite, a definite carbide
Of iron. harder than glass and very pril-
tie. 3. Pearlite, a mixture of SIX parts
Of ferrite to one Of cementite. =. Marten-
site. a hard, brittle solid solution OF
carbon up to IL per cent. IN iron. ,:
Austenite, a soft, non-magnetic steel OF
II to 1.6 per cent. carbon, suddenly quencn-
ed from iOO0' in ice water. s. GraPnite,
or carbon, found in slowly cooled cast
iron. Ordinary wrought iron and the
softer steels consist of about SO per cent.
Of ferrite to 1 of cementite; while the
harder steels may contain as much as
= per cent. of cementite, and in white cast
iron il NAV rise to 81 per cent The
maximum strength is reached with about
* ner cent of cementite. High-carbon
tool-steels. hardened by quenching, are
almost entirely martensite.
Ieft-evedness is looked upon by DR.:
George M. Gould, of Philadelphia, as OF
greater significance than left-handedness.
He is seeking facts concerning the two
and their association, but suggests that
both may be due to the abnormal location
Of the speech center in the right side OF
fhe brain. lie believes ambidexterity
should be discouraged, while he has seen
only bad results in the attempt to correct
a decided use of the left hand.
An unweIcome settler from America is
being fought by the Queensland Gov
eminent. This is the prickly pear, kind
a kind of cactus that has proven so Wig
orous a weed that $4,000 has been offer
ed for a sure means of eradicating it.
The latest of the lamps attempting to
take advantage of the great brilliancy OF
the electric arc in the vapor of mercury
has Just been perfected by c. Orme Bas-
tan and A. E. Salisbury, English cleo
tricians. 1t resembles the Nernst lamp
in size and appearance. The light pro-
ducing part, consisting of an H-shaped
glass tube with bulb-shaped lower ex-
tremities into which platinum wires pro-
ject, is exhausted of air, and contains just
enough mercury to fill the bulbs and
food the cross-tube, which is slightly
curved downward. The lamp is so hung
that the legs are normally vertical. A
soIenoid above the globe is connected in
series with the mercury through the plat
mum wires, and when the switch is closed
the solenoid attracts an armature, fitting
the tube, and slightly separating the two
sides of the horizontal mercury. An arc
forms across the gap, frightening to about
three inches as the increasing pressure
forces the mercury up the side tube. The
light is very vivid, but its lack of red rays
causes all red Objects to appear black,
and this defect is remedied by placing
small red glow lamp alongside the tube.
The light is cheap and powerful, while
its richness in actinic rays specially adapts
it to Photographic use.
Reviewing the steam engineering prog
ress of Japan, Prof. Bunji Mano finds
that the first land engine was placed in a
spinning-mill at Kagoshima in 1868, and
that the first made in the country came
about ten years later. In 1901 the land
engines in use numbered 1888, with
horsepower of 1882. The first railway,
with four British locomotives, was opened
between Toxic and Yokohama in 1872;
to-day the railway mileage is 1859, with
1869 locomotives. The first steamer was
brought from Holland in 1855; the first
built in the country dates from 1866. The
present number Of steamers is 1919, with
a gross tonnage of 645,926.

An extraordinary case of multiple
personality" has been described to the
London Psychical Society by DIR. Albert
Wilson. In 1895 well-behaved, intel
ligent girl of 1914 years was taken sick
with influenza, followed by meningitis,
and after an illness of six weeks her
facial expression and manner changed,
and she became childish, clipping her
words. She had to be re-taught the mean
ing of words, while she wrote each one
backward. Her characteristics, moreover,
changed rapidly, so that she often seemed
three different persons in FIVE minutes,
and DR.. Wilson has classified altogether
ten of these distinct personalities, besides
her own normal one. She was at times
more childish and ignorant than at other
times. Sometimes she was deaf and dumb;
at other times paralyzed in the lower
limbs; sometimes she wrote forward and
spoke backwards; occasionally she became
an imbecile, blind and apathetic; and in
another change she was an acrobat, try
ing to climb a wall on her head In
her blind stage she could read writing
and determine color by touch. She has
now settled into a single personality, not
her original one, and in this, but in no
other she understands French.
Dusty work seems to be responsible for
consumption to an unexpected degree. In
2161 cases of tuberculosis treated at the
sixty institutions of the German Empire,
1895 patients had been employed in dust.
The kind of dust was not stated in 431
cases; in 1872 cases it was metal dust;
in 12O, stone, coal or glass dust; in 116,
wood dust; in Ill, wool dust; in 126,
various other kinds of dust.
Cryostase-a mixture of equal parts of
phenol, saponin, camphor, and little tur-
pentine Oils a scientific curiosity. 1t
reverses ordinary experience by the sur
prising property of liquefying in the cold
and solidifying in heat and continuing
to change with temperature. Albumen
is solidi6ed by heat, undergoing no furth-
err change.
