NEARLY 100000 persons die annual
" in France, which gives 1880 deaths
per diem in round numbers. Taking
the number of deaths as it is observed
in France, we obtain as the total of the
| annual deaths for the whole world 3d.
693, 350-that is, 1890 persons die
daily. AS compensation, the number
of births is estimated at seventy per
minute. or 1O4,800 per diem.
A GOOD silver-platlng fluid is made as
follows: Dissolve one ounce of crys-
tails of nitrate of silver in twelve ounces
of water. Then dissolve in the water
two ounces of cyanide of potassium.
Shake the whole togetherrand let it
stand until it becomes clear. Have
| ready some half-ounce Walls, and fill
them half full of Paris white, or fine
whiting, and then fill up the bottles
with the liquid. and it is ready for use.
The present necessity of American
agriculture is larger crops at the same
cost, or less proportionate cost, than
| our present small ones. This result
can only be secured by additional fer
tiizing. The present average of our
crops is not more than one-fourth of
that which the soil is capable of pro-
| ducing, and this extra three-fourths
may be produced without any more
labor by the use of fertilizers or addi-
tional manures-but fertilizers chiefly.
A WATERPROOF whitewash may be
made as follows: "Take half bushel
OF lime, Stake it with boiling water, and
cover to keep in the steam; strain and
add seven pounds of salt dissolved in
hot water; three pounds of ground rice,
boiled to paste, and added hot; hail
| pound Spanish whiting, and one pound
clean glue, previously dissolved to a
thin paste; add five gallons hot water,
and stir the whole cover it, and keep
it a few days. It must be used hot.
One pint covers a square yard"

TO MEASURE grain on the floor:
Make the pile in the form of pyramid
or cone, and multiply the area of the
base by one.third the height. To find
the area of the base, multiply the
square of it's diameter by the decimal
1854. Example-A conical pile of
grain is 8 feet in diameter and 4 feet
high, how many bushels does it con-
tain? Solution-The square of 8 is 81,
and Ga times 1854 times 4-3 equals
S3.776, the number of cubic feet.
Therefore, 83.776 times As equals
s6702 bushels.
SUBSTITUTE FOR CALoMEL.- Sulphate
of manganese is low being introduced
as substitute for mercury in the vari-
GUS bilious troubles. In jaundice, he
patio dropsy and hypochondriasis it is
stated to have produced most remarka-
able results, and in hemorrhoids and in
congestion of the fauces and bronchia
it is proved no less efficacious. Ansmic
patients. who cannot take any of the
preparations of iron, are enabled to
take iron with benefit if combined with
two to five grains of sulphate of man
ganese. It is found preferable to adj
minister the manganese in ten grains
| to scruple dose in glass of water,
adding little citrate of magnesia to
cause efervescence. By these doses
large bilious objections are produced.
Half drachm is said to be the utmost
dose ever necessary, ten grains being
usually quite sufficient.
ACCIDENTS FROM CHLoRoFoRM VA
PoR.-A preventive for those accidents
whichso frequently occur in the admins
tration Of chloroform to produce anaes-
thesla has been suggested BY DR..
Wachsmuth, of Berlin, the method con
slstlng simply in the addition, of one
part of, the rectified oil of turpentine to
five parts of chloroform. The oil Of
turpentine in vapor appears to exert
stimulating or ife-giving effect on the
lungs, and protects those organs from
passing into that paralyzed state which
seems to be produced by chloroform
narcosis: It appears that DR.. Wachs-
muth, while lying on q sick bed, acct
dentally breathed the vapor Of turpen-
tine, and he experienced from this q
strongly refreshing feeling fact
winch induced him to try the plan of
adding oil of turpentine to chloroform
when using the latter for anmsthetic
purposes.
