Exhaustive tests for years have COLI
vinced Joseph L. Ferrell that sulphate
of aluminium Is the best freproofing for
wood. Unlike sulphate or phosphate of
ammonia, which check flames by emit
ting ammonia gas, the aluminium COM
pound forms an infusible and non-con-
Quoting coating.
The late discovery in strawberries OF
salicylic acid, a specific in acute rheu-
matism, has seemed to confirm the idea
that these berries are desirable artl-
Gle of food for rheumatics. The effect
of the fruit cannot be due to the sail
cylic acid, however. as less than the
hundredth of a grain per pound Is
found.
Important tests of the fatal proper
ton of carbonic oxide in the air have
been made by Prof: Mosso at the Turin
Physiological Institute. A heroic sub
ject was confined three times in her.
metically sealed iron chamber, the air
of which was mixed first with 1888 of
carbonic oxide, then with 1885, and
lastly with 1888. On the last expert
ment the man ceased to breathe. being
restored only by oxygen.
While urging that the proposed bio
logical survey of the North Sea should
seek means of favoring fishes and their
food supply, Prof. W. G. Mcintosh de-
clares that no important species is in
danger of becoming extinct. The fishes
were not eXterminated by the swarms
of gigantic destroyers of rept1Ilan
times, when the destruction must at
least have equaled that Of to-day by
man, and future extinction need not be
feared.
Alcohol Is coming into considerable
use for illumination in France. The
fame is made luminous by the addi-
ton of sufficient coal-oil or crude ben
zine, or the ordinary non-luminous
fame is used to give incandescence to
a WeIsbach mantle. The latter is the
more important method. Some lamps
have from sixty to eight hundred can
dle-power, and these large portable
lamps, carrying their own illuminant.
seem to have advantages over gas or
electricity for many purposes. The
best of the burners yield about thirty
| candle-power hours per ounce Of alco-
, hol. -<....
Tests have recently been made on the
Boston and Maine and the Florida
East Coast Railroads to determine the
value of oil as fuel for locomotive en-
/ gines. On the Florida Railroad it was
found, after months experimenting
with a locomotive hauling its regular
load, that 1928 gallons of oil did the
work of one ton of coal. Another test
showed 1918 gallons Of oil TO be equiv
alent to a ton of coal. In the Boston
and Maine experiments the ratio was
| 140.26 gallons Of ell to one ton of coal
| 1t was found that the engine could be
urged to a greater capacity with oil
than with coal, and this with a smoke
less fire.
By singular change of circum-
stances, the gold miners of Hastings
County, Ontario, Canada, who for
years were baffied in trying to extract
the precious metal from its matrix by
the presence of arsenic in the ore, have
lately found the arsenic to be more
profitable than the gold. This. is due
at once to the great purity Of the Cana
dian arsenic, and to the rapid exhaus-
ton of the arsenic deposits Of England
and Germany At the same time, the
introduction of a successful method
of separating the gold increases the
profit of working the Canadian depos-
it's, because every ton of the arsenical
ore carries from 81 to $50 worth at
gold.
