In the animal and vegetable king
doms are found two distinct forms of
fellewshipin which dissimilar organ
isms live constantly together. In one
form-parasitism-one Of the associa-
ted organisms lives at tho expense of
the other, A., for instance, the mistletoe
on the apple.tree. In the other form,
the advantage Of the companionship is
mutual, as in the case Of the WELL
known hermit crab, one species of
which picks up an empty she'll for an
abode and shares this and its food with
sea anemone, which in return pro-
tects its host by means of numerous
long threads charged with singing acid
which it shoots out on the slightest
alarm. BY experiment at Naples it
has been proven that the compact be-
tweet these two partners is 80 clost
that one is indispensable to the other.
A still more remarkable illustration
is drawn from the candle-nut tree OF
South America, which forms an alliance
with species of small black ant, to
their mutual benefit. To this curious
partnership, which appears to exist
among many animal ana vegetable
species, but which naturalists are Only
just beginning to study. the name Of
symbiosis has been applied. At the
last meeting of German naturalists,
Prof. Hertwig pointed out that such
inter-dependence of organisms may
have played an important part in the
developement Of specier.
Animal life is very abundantin in some
parts of the world at great depths in
the sea. This is illustrated by the
fact that during last summers explor-
ations 10y the French steamer Talisman
one haul Of its net brought up, from a
depth of 800 fathoms, 1000 fishes and
nearly 1000 crustaceans of different
kinds. This capture was made in the
Atlantic, near the Cape Verd Islands.
To the universal recognized Eve
senses-sight, hearing, taste, smell and
touch-Sir VIM Thomson, following
out = suggestion by DR.. Thomas
Reid, adds sixth by dividing touch
into the sense of roughness or Of
smoothness and the sense of heat. 1t
has been suggested that We should
also have a sense which can perceive
the remarkable force which is exerted
by magnets. Every scho olbov kno, .
how iron and steel are attracted, and
Faraday discovered that if piece OF
copper or silver is dropped between
tho poles of a powerful electro magn t
it falls slowly as if sinking through
mud. To determine how this mag
netic force is felt by the human system,
Lord Lindsay and Mr.. c. F. Varley
made AL slectro-maguet so large that
any person might place his head be-
tween the poles in the centre Of
tho powerful influence which resist
ed the fall Of copper like mud. Sir
VIM Thomson declares that the result
was marvellous, the wonderful thing
being that not the slightest effect was
perceivd by the human body. He is
unwilling to accept this experiment as
conclusive, and thinks that It may yet
be shown that we have a magnetic o,
electric scnse-which, however, has
nothing to do with what he terms
"that wretched superstition of animal
magnetism, and table-turnlng, and
spiritualism, and mesmerism, and
! clairyo vance. and sp,rit- AIMING"
