on the adulteration of food, in VIII CHI
he recommends the public fogging of
certain classes of adulterators.
A little extract of ginger mixed with
hot water and sugar will counteract
the bad effects OF wetting.
Since the Introduction of the electric
light, the matter of its effect on the eye
has been much discussed. The result
of recent investigation by Partisan
scientists was that it was not hurtful.
An eminent Arabian natur Alist and
ply stefan of the tenth century, named
Temini, states that in ancient times
the bitumen of Jud@a was used to
perserve the vine from the ravages of
parasites.
To produce light and dark shades of
gold leaf the metal is alleged with sill
yer and copper. The addition of the
baser metals lessons the malleability,
and as the leaf is sold by superficial
measure, and not by weight, adultera-
ton is kept at the minimum.
A relis BILE pill for dyspepsia: Dias
tase, 10 grains; pepslne, so grains; ex-
tract of gentian, so grains tartaric
acid, so grains powdered rhubarb, 30
grains, and gentian, q. s. Divide into
three-grain pills, and silver, if desired.
Dose, two or three pills, shortly before
meals.
In 1880 the value of sugar of milk
imported into this country exceeded
$25 900. The Boston Journal of Ciena.
istry asks if it is not about time that
some of our large cheese factories under
took the manufacture of gar from
the whey, which yields about 5 per
cent. of this substance.
The italian Government is organic
ing for the navvies who are employed
in the Tunnel, and still suffering from
an@ mia and other ailments arising
from the bad air and high temperature
in which they are compelled to work,
a sanitarium for their reception high
up on the st. Gothard-pure mountain
air being the most efficient remedy for
diseases of this class.
In hardening small tools, says the
american Mochinist, or any article of
steel that is thin or light and heats
quickly, il is advisable to remove, on
grindstone or emery wheel, the scale
formed in forging before heating. The
sc lie being of unequal density, if it is
not removed it is generlly impossible
to heat evenly; besides the degree of
heat can be better observed if it is
removed.
The american Chemical Journal
says crysiallized anhydrous glucose
has hitherto only been obtained from
alcoholic solutions. Arno Behr has
recently found that glucose can, under
certain conditions, be obtained as the
anhydride in crystallized form from
solutions in water. This result may
be accomplished by putting some crys-
tallized anhydrous glucose in a coD-
/ centrated aqueous solution of glucose.
Surgeons know the value of the ex-
pansive power of peas and other grain
in making anatomical preparations.
No one has any idea of the force exer-
ted until a test of it is made. An
italian vessel, laden with rice, put into
East London some time ago leaking
badly. A strenuous effort was made
to pump out the water and unload the
cargo. But the rice continued to swell,
and finally the vessel was violently
burst asunder.
A Connecticut mech snic has made
trial of rotary files for finishing planed
surfaces. H is of the opinion that
quicker and truer work can be done
with these than with hand files. and
that the surface Is in better shape
for trueing with the scraper. His ex-
periments have been confined TO the
planer; but he believes that his device
may be pre- perly aud economically
adapted to the lathe and milling ma
chine.
Starch is much more readily convert
ed into sugar when under pressure
than otherwise. Not only, says con-
temporary. is the diastatic action of
the soluble albuminoids increased but
when the pressure is great the small
percentage of free acid which is found
in all cereals is sufficient to convert
rapidly the starch into sugar. 1t is a
matter of surprise, therefore, that
brewers do not mash under pressure.
The st. Gothard Line not only has
the longest tunnel in the world but
twenty four miles, or more than one
fifth of the whole line, consists of tun-
nels. Many of these have had to be
constructed in spiral or corkscrew
fashion, whereby, while making the
necessary rapid ascent from the valleys
to higher elevation, the line is per-
fectly protected against the avalancnes
