| About 5000, 600 sponges per yea
are taken from the sea around tn

the rocks.
The question is now raised whethe
the distinction which is made between
force and matter is not fallacious. and
whether matter should not be consid
cred to be force itself, manifested in
endless diversity of adaptation to oul
nature and wants.
Experiments have been made in
Russia on the culture of minute para.
site plants for the destruction of inju-
rious insects. Caterpillars feeding on
the beet-root were abundantly destroy
ed. Various other parasites have been
known to produce epidemics in insects.
The inventive Japanese have be-

In the matter of the use of galvan-
lied iron water-pipes or reservoirs,
Science Neaos takes the ground that it
Is practice attended with danger to
health, on account of the action of
water upon the zinc coating, forming
soluble and poisonous salts. Certain
cases have come to its knowledge
where sickness and even death have
occurred from this cause.
-Experience shows that new Chin
ney hnes for boilers should be made
not less than eight inches square; they
should be straight, and to prevent any
blow down" ought to rise completely
above all roofs and objects Immediately |
'urrounding; long iron smoke-pipe |
connections are to be avoided, and as
ew elbows used as possible, the fact |
'eing that each elbow and extra length
II pipe is detriment to the draft and
damage to the working capacity of
he boiler.
-Colored relief impressions are now
Manufactured by an ingenious German
'rocess. 1t consists in coating the
beet metal with certain isolating
oat, and on this is painted an elastic
ack ground, capable of absorbing
olors, and on which the desired pat
srn is placed. By this means tn
fetal plates can be pressed into reliefs
'ithout any displacement of the color
lg matters, and the latter are not
forwards affected by chemical action
their constituents with the metal.
