Prof Vornderweyde, in q few remarks
at recent meeting of the American lnsll-
tute, said he is satisfied many diseases now
ascribed 10 other causes are in reality pro-
duced by animalculB, and thinks it VIII not
be long before the microscope will begin TO
show this The itch" insect, and the late
Undiscovered trichinia spiralis are eX
| amples He also thinks that cancer, and,
perhaps, cholera, will soon be found to pro-
coed from parasitic life, and that with the
discovery will be found the means OF cure
Father Secchi, the celebrated astrono=
mer and natural philosopher, whose re-
searches we have so often had occasion to
mention, is now in Paris, and passes the
greater part of the day at the great exhibit
ton, where curious clock OF his invention
is to be seen, which automatically marks
down on long piece of paper that is I'M
rolled at one end and rolled up at the other
the hour, the direction and intensity of the
wind, and quantity of rain that has fallen
within given time, the height of the ba-
rometer the hygrometric state of the at
mosphere All this work is effected by a
half dozen pencils constantly in motion,
and which perform their, task with unerr7
ing fidelity.
The earth-wOrm, says an observer, .ex-
uaes trunspar rent, sticky substance, which
serves it for taking hold on objects to be
conveyed toits holes and also as the means
of finding its way'back to the hole, by the
Shiny trail Although the worm cannot
see, it can hear very we'll IL very moderate
noise at the distance of three feet causing
| it, to contract and attempt to hide. rilt
would also seem that theworm is very sensl7i
tive to warmth. With a small stick could
touch it before il. was aware Of anything
being near it : but in. cautiously putting my
hand toward awor1n, it would contract its
body when my finger was an inch from it,
1t would seem from this that the warmth
of my hand made the worm aware of its
approach"
The common snail, which seems like
little more than jelly,1s furnished with
quite a firm jaw of a crescent shape, con
the upper lip. In come species this jaw
has slight smooth projection on the cut
| ting edge, and in others it is notched. 1t
is capable of biting through the leaves of
lettuce or cabbage, and when feeding, the
nipping sound of the bite can be heard,
and the little seniclfcular cuts on the leaf
are distinctly seen. but the more curious
part of the eating apparatus, is the tongue
with which -thessHail laps its softer food,
and which is also furnished with sharp,
hooked, rasping denticles to the incredible
number, in some species, of nearly $4,000,
arranged in regular longitudinal and trans
verse rows, on bit of membrane not a
quarter of an inch long and half as wide.
A wonderful vtaltyis found in these Crea-
lures for reproducing portions cut AWAY,
and sometimes even the head grows again
after decapitation.
| Captain Ericsson has performed many
services fer his native country, Sweden,
for which the legislature has voted him an
address of thanks. Among the latest and
perhaps the most singular of these services
is his plan of fleet, of light-dra gunbeats
for the innumerable and devious channels
along the island girt coast and among the
network of lakes peculiar to that country.
One of these boats, iron-elad, is already
CONSTRUCTED at Motata. The deck is COM
pletely below the water level, and is pro-
tected with plating. A sort of oval tube
or sheath, open at one END, rises above the
deck higher than the water From this
points a 15-inch gun, which does not train,
but moves according TO the position given
to the boat by a rudder so@eonstructed as
to turn the bow in the wished for direction
The motive power is applied by the arms
of thirty-two men, who act by a simple
mechanism on screw with four f1anges.
| The power thus obtained is said to be thir-
