The Railroad Gazette of June 10th gives
a total of "a miles of new railroad, making
l,574 miles thus far this year, against l, 500
miles reported at the corresponding time in
1880, 66l miles in 1879, 4l3 miles in 1873.
so miles in 1876, 296 miles in 1873, 537
miles in 1874, and /, III miles in 1878.
One of the things against which all deli
cate people should be warned is veal cut
lets. Bread crumbed and fried in fat is
positively very injurious, and neither
nourishing nor digestible. Altogether pork
steaks aud meats that are put into pot
of boiling fat are utterly useless and can
not be dealt with
w. G. Bagnall, of the Castle Engine.
Works, Stafford, England, has just COM
pleted the tiny engine, the Hampson. p"
The cylinder is three inches the wheel,
thirteen and a half inches and the max
mum width only thirty-one and a half
inches three horsepower nominal gauge
eighteen inches. The engine has been
tested, the ir0nmoBgeT says, with salts
factory results. 1t is destined for South
America.
The Journal de PfGYmGcie Ct de Chime
says that two pupils OF the Communal
burnt in the face with boiling sulphuric
acid, owing to the rupture of a retort. The
author covered their faces with q soft
paste made of calcined masnesia and
water, and applied it in layers of two nm.
in thickness. As portions OF the coating
split off. the paste was reapplied. All pain
ceased in about quarter OF an hour, and
after some time-fve hours in the slighter
of the cases. and twenty-four in the more
severe-no further treatment was needful.
Their faces show no trace of injury.
Steaks and chops are not the best dishes
for weak digestion. Either they are but
half done or they are charred too much.
Meat that is to be really nourishing, and
yet be easily digsshble, must be thor
oughly permeated with heat. A steak or
chop prepared with care Will be digestible
to certain extent, but great trouble
should be taken that the outside is.not
burned and the inside raw, and of either
steak or chop, but small piece should be
thought sufficient The pounds of steaks
and chops that are often devoured by peo'
pie, who can scarcely cram them into their

A tricycle. driven by electricity appeared
lately in one Of the streets of Paris. NJ.
Trouve writes of it to La Nature, stating
that the tricycle. was of English make and
very heavy (55 kilogr.), and that he had
adapted to it two OF his small electric
motors, fed by three Of the secondary ele-
ments or accumulators OF electricity, which
serve for his polyscope. The vehicle,
mounted by friend of his, ran several
times along the Rue de Valois as fast,
at least, as good, ordinary cab. The
total weight Of the vehicle, with
its rider, was about 100 Kilograms,
and the effective force produced by
the two motors was kilogrammeters.
The experiment lasted an hour and a half
In view of the results, NJ. Trouve has set
about the construction of a motor which
will produce as much as the two others, so
as to obtain 4 greater velocity. say 20 to 80
kilometers an hour.
The tapeworm is able to live in the
stomach because of its ability to resist the
digestive action of the fluids normal to the
stomach. In a stronger peptic solution
the live worm succumbs and is digested
like any other flesh Accordingly French
physician treated with strong. doses of
pepsiue a child who had passed segments
of large tapeworm. About 40 grains of
pepsine were administered daily for five
days. The child experienced no harm
and showed no special symptoms. Then
q proper dose of sulphate of pelletierine
with. castor oil was given, and the dis
charges showed no signs of the worm.
Subsequent experiments with vegetable
pepsine-papaine- is much more &C.
tive, are said to have given very promis.
ing results. One child passed fragments
of tapeworm ten inches in length, softened
and partially digested.
1t has been found that wires, when en-
ployed for a telephone circuit, are much
more susceptible to disturbing causes than
when employed for transmitting telegraphic
signals. 1t has been observed that the
slightest friction, such as will inevitably
occur from the ordinary mode Of joining
telegraph wires, the closing OF pressure
screw anywhere on the circuit, the slight
est blow upon the wire, vibration
from wind, the Ordinary modes OF
support, etc., which produce no percep-
tible effect on the transmission of tele-
graph signals, are great hindrances to the
transmission of voice vibrations, and thus
confine the telephone to comparatively short
circuits. 1t is thought ii these hindrances
could be avoided, the telephone circuit
might be continued to as great length as
the telegraph-even across the ocean. Ex-
periments are now in progress to determine
all the facts connected with this matter.
These experiments will involve the charac-
ter, inequality and size, of the wire to be used,
the best form of support, and q substitu.
ton OF soldering the ends together, in
stead Of the usual mode of joining. There
is much reason for the belief that the tole-
phone may ultimately as fully supersede
the telegraph for long, as it slreadY has
for short distances.
