In London the milk bought by the
officials for analysis nearly invariably
contains M excess of cream.
A CORRESPONDENT of the Scientific |
Republican recommends common glue |
as an effectual remedy for cuts and
bruises.
Ir is said that if one part of sugar is
dissolved in three parts of water. and
digested with one-fourth part of calcic
hydrate, the resulting liquid will readi-
~ dissolve glue warm, and the solution
will remain fluid on cooling, without
having lost any of its adhesive proper
ties.
NJ. PATERA proposes to render woven
fabrics non-inhammable by using. in.
stead of sodic tungstate, mixture of
four parts borax with three parts mag
nesic sulphate. One hundred grammes
of the mixture are to be dissolved in
three hundred to four hundred cubic
centimetres of water, and in this solu-
ton the fabrics are soaked, then wrung
out, dried and ironed. Another mix
ture proposed for the purpose is that
OF ammonia sulphate and gypsum.
Hot alum water is said tobe valuable
as m insecticide. Two pounds of
alum dissolved in three or four quarts
boiling water, and applied to all cracks
and crevices, will keep out and destroy
all red and black ants, cockroaches,
spiders, chinchbugs, fees, etc., Trav-
elers in strange countries should
always carry small package of pow
dered alum or borax with them to scat
ter round their pillows where they sus-
pect strange bedfellows.
NJ. ON1Mus has found that when the
wire OF q bobbin is bad conductor of
electricity the muscular contraction
produced is stronger, and the impression
ON the cutaneous nerves is less vivid
than with good conductors, as copper.
These effects are more marked the
greater the exterior resistance. The
current induced in bad conductors has
greater tension than that in good, and
less quantity. Coils ,of German silver
wire may, in accordance with these
facts, be advantageously used in cleo
tromedical apparatus.
THEfollowing mixture is said to make
very good barometer, it being very
sensitive to weather changes: Mix
with p drachms of camphor, dissolved
in 10 drachms of alcohol, with 40 grains
of saltpetre and 40 grains of sal am
moniac in 9 drachms of water. This
mixture should be placed in q four
ounce vial, with piece of cloth tied
over its mouth, and placed in a good
light, out of the sunshine, where it can
be observeded without handling. When
the weather is fine the fluid is clear, but
on the least change the chemicals rise
from the bottom in beautiful frend-ike
crystals.
A CORRESPONDENT of Nature saws that
during the hurricane of October 9Th,
1873, he was residing on the west shore
Of Biscayne Bay, South Florida.
In the early part Of the gale, and while
it was approaching it's height, he noticed
overhead innumerable man-of-war
hawks" They seemed to be "laying
to 4" Ito use a nautical phrase), with but
little motion of their wings their
heads were towards the wind, but in
stead of moving backwards they seemed
to drift off in a line calculated to take
them directly away from the storm
centre. This action he considers to
have been developed from experience
by the ancestors of the "man-of-war
hawk, and to have become 80 organic
ed in the race as to cause them to leave
the track of the approaching cyclone
instinctively.
Ar recent meeting of the Geologi-
cal Institute, of Vienna, the director,
F. V. Hauer, stated that towards the
end of the international exhibition he
had asked almost all Austrian and q
great many of the foreign exhibitors of
ores, Goals, or other useful minerals, to
present these objects to the museum of
the Institute. This request was very
successful, more than q hundred exhib-
itors having offered the whole or part of
their expositions to the Institute. and
the number of the givers is increasing
still every day. Out of the objects OBJ
tanned in this way will be formed par
ticular collection of useful minerals
from Austria and from abroad, embrace
ing ores, Goals, salts, building stones,
al sorts Of useful clays, limestones, etc.
This collection, it is supposed, will
form, when finished, one Of the finest
in the world.
