not in any case exceed $40 gallons per

In paper by Professors Ayrton and
Perry, read lately before the Physical
Society, London, there is prediction
that gas engines will be employed in
the propulsion of vessels.
Soap bubbles which will last very
long time for laboratory experiments
are generally made of this solution:
Dissolve one gramme of dry Marseilles
soap in 100 grammes of warm water;
filter, and to every 100 cubic cent?
meters of the liquid add forty grammes
of white sugar.
To produce pure black upon wood
the following receipt is given: Pour
four quarts of boiling water over one
ounce of powdered extract of logwood,
and when the solution is effected add
one drachm of yellow chromate of po-
peat the application of this mixture
unit il the wood is dark enough.
During the fractional distillation of
tiuorinc Mr.. w. X. Hodgkinson noticed
the formation of an orange-red sub
stance, which he considered likely 10
be an oxidation product. Its isolation,
however, is extremely difficult, as it
decomposes when distilled in vacuum,
and is equally soluble with the hydro
carbons which accompany it.
Silveroid is the trade name given to

that cadmium enters into it, 1t is in
tended to take the place of the brass,
bronze and gun metal classes of alloys,
and if all turns out to be true which is
spoken in its favor it will soon do so,
especially in the manufacture of arti-
sles which must be strong and capable
of taking fine polish.
A contemporary believes that the
largest locomotives in this country are
those of the Central Pacific Railroad
Company-cylinder 10 inches diameter
by 80 inches stroke; 8 driving wheels,
"a inches diameter; weight in working
order, 1913, 900 pounds; built at railroad
shops. There are now building at the
shops of the same company engines
with cylinder II inches diameter by sc
inches diameter; weight in working or
der, 100000 pounds.
A cloud so dense as to prevent per-
sons from reading bold type at mid
day passed over a great part of Ian
cashire, England, recently. The un-
usual darkness lasted about an hour.
From the accounts given by intelligent
observers of the occurrence the cloud
must have consisted of finely divided
carbon dust. Rain which fell cOpiously
in some places was as black as ink. AT
other localities where hail or snow fell
it was noticed that each was likewise
black. Not long time ago such a
phenomenon would have been deemed
Ominous.
c. f. Bessey calls attention in the
american Naturalist to an enormous
puff ball This particular fungus
found by Professor X. +. Call in Herk-
inner county, n. Y, belonged to the
species known as Lycoperdon gigan-
teum. Photographs of it were taken.
1t was irregularly oval in outline and
much flattened. It's largest diameter
was five feet four inches, its smallest
four feet six inches, while its height
was but nine and half inches. This
specimen, the writer says, is the larg-
est of any of which measurements
were attainable for comparison.
The Lancet condems the practice OF
giving and taking such depressing mar
cotics as choral and bromide OF
potassium as remedy for sleepless-
ness, as mischievous and wholly indie
fenslble. 1t is as clumsy in theory as
knocking a man down because he
needs rest, and yet as by common con
