CEM1Nr FOR AQuAR1A.-An adhesive
cement for aquaria may be made, &C.
oording to Klein, by mixing equal parts
of flower5 of sulphur, pulverized sal
ammoniac, and iron filings, with good
linseed oil varnish; and then adding
enough Of pure white lead to form q
firm, easily worked mass.
MARINE FISHERIES OF MAINE IN 1873.
According to The Gloucester Tele-
graph, the total value of the cured and
packed herring, goldfish, haddock, pol.
lock, and mackerel in Maine last year
will approximate $500, 900, giving en-
ployment to not less than $50 men. In
catching cod and mackerel 661 vessels
are employed, aggregating 46, 1876 tons
burden.
oMEAr BIsCUn.-A new form of bis
cult for troops was used in the Russian
campaign against Khiva with very sat-
is factory results. This was composed
Of one-third rye -four, one-third beef
reduced to powder, and one-third of
pulverized sauerkraut. Great relish
for the food and excellent health of
those who used it were characteristic of
the Russian soldiers throughout the
campaign. :.::i
BEAuT1ru1 WHITE FOR Woo1.-Ac-
cording to the Deutesche .Wollen-
Gewerbe Organ beautiful white may
be impaired to wool by working it about
anlhour in bath at 122 degrees, COM
posed, for so pounds Of wool, of alum,
2 pounds; tartar, 1 Of q pound sui
phuric acid, pound soluble indigo,
8 ounces archil, IL ounces (orf, iodine
violet, soluble in water, 28 grains). and
Afterwards allowing it to Lie for about
two hours in solution of pound of
chloride OF barium in water at 122 de-
grees. There is also gain In weight
OF about 18 per cent, by the precipita-
ton OF sulphate Of baxyta (permanent
white), in the fbers of the wool in the
second bath. :. "
One CAUSE OF THE PorATo DISEASE.
Among the numerous causes cf the
potato disease, according to DR.. Alfred
Carpenter, q principal one consists in
the accidental introduction of q dis
eased tuber into pile destined fol
subsequent planting, the spores being
transmitted from one to the other. 90
that the entire mass is more or less af.
fected. Dr.. Carpenter thinks that, "a
q general rule, the germs of disease
must be pre- existing in the mother
plant, but that they NAV remain en-.
tirely dormant or altogether inactive
for . considerable period, or until fa-
vorable conditions of excessive mois-
ture, heat or other causes combine in
proper ratio to quicken their growth.
II measures can be taken completely to
disinfect the seed-potato before plant
ing, he thinks no apprehension need be
felt az to the future.
WRATHER-PRooF WASH FOR WOOD
According to Kuhr, a cheap and con-
venient reddish-brown coating of fer
rocyanide of copper can be formed upon
wood, which not only adheres firmly
and resists the weather, but also pre-
serves the wood by keeping it free from
moss, ETC., as we'll as from Injurious in
sects. To produce this resuitswash the
surface previously brushed with 10
luton OF half pound of yellowprus
state Of potash in a gallon. Of water)
with solution of one pound of blue
vitriol in q gallon of water. The shade
can be regulated by varying the strength
of the solutions. Since the wood il
stained rather than covered, it's texture
remains somewhat visible, which is not
Objectionable, and by coating it with
linseed oil varnish not only it's dura-
bility is increased, but gloss is i'm
parted, without which it is rather dull.
ANTAGONIST BErwERN B111ADoNNA
AND THE CA1ABAR BEAN.-According to
numerous experiments by Prof. Fraser,
22} grains of atropine, and II grains OF
the extract of Calabar bean, are the
smallest amounts of these substances
respectively necessary to kill rabbit
weighing 81 pounds and the, sulphate
lot eserine has stenfeld he-e6eet~-of the
extract. Dogs are more easily affected
than rabbits by atropine /; Is grains be-
ing sufficient to kill dog weighing 16
pounds. The minimum Of eserine nee.
essary to produce death may, however,
be greatly exceeded, doubled. or even
trsbled without poisonous effect, if g
certain amount of sulphate of atropine
is administered with It, and the cues.
ton naturally arises whether eserine
and atropine neutralize each other il
cases Of other animals, especially since
dogs and rabbits are hot very sensitive
to atropine. =.

CoMBUsT1BLE.-The following process
for the preparation of starch that will
render fabrics incombustible, il given
by Hagar: Cover 10 parts Of white,
pulverized bone-ash with so parts oi

SulDhuric acid. Stir the mixtnra thor.

place. Then add 100 parts Of distilled
