Bunsenite is the name proposed for a

labor of one hundred hands.
Even in the best qualities of glass, the

nothing appears to impair the purity of
Its Transparency; but when it is looked
at obliquely. minute and regular strle are
easily discovered.

The first reaping machine in history
was used in Gaul, A. D., 70. Pliny says
1.-The mode of getting in the harvest
varies cons iderably. In the vast domains
Of the provinces Of Gau!, a large hollow
frame, armed with teeth, and supported
ON two wheels, is driven through the
standing grain, the beasts being yoked
behind it; the result being that the ears
are torn off and fall within the frame. >

In the milt of 4 Goldfish. or in water in
which certain vegetables have been in
fused, the microscope discovers animal
cule, of which many thousand together
do not equal in bulk grain of sand, ant
yet many of these are supplied with or
gans as complex as those of whale OF
an elephant. In q single pound of sucf
matter there are more Lying creatures
than human beings on the face of th'
entire globe.
Preserved peas are. far more commonly
than people think, colored with salts o.
copper, TO counterfeit the fresh, natura
tint, If they are put up without bein9
',.rtificially colored they have yel!owisl
} hue, aud this suggests an easy test of the,
lpurity by simple inspection. Past, u
has found that out of IA cases of pea
which he apalyzed, 10 had been treatet
with copper, 10 such an amount IN SOM
5 instances that this poisonous adulteran
}. was equal to one-ten-thousandth of tn
r enlire mass, minus the water.
2 n. Richet's experiments have determin
ed several very interesting facts regardln!
: digestion. Although the stomach usual,
is empty four hours after meal is taken
the sensation Of hunger is not felt unit
after the lapse of six hours. Ordlnar
food, such as meat and fatty or starch
substances, require to be acted upon in th
: stomach for three o. four hours, and the
the entire mass disappears in aboue l
minutes into the pylorus. Milk is take
: up after the lapse of from an hour and
half to two hours; and the absorption o
= water and alcohol is very rapid.
