MEMS FIVE SENSES.
CURIOUS FACTS ABOUT THEM NOT
GENERALLY KNOWN.

by Either Very Hot or Very Cola
Liquids-The Ear Is n Wonderft!
OrEan-Tke Eyes Easily Deceived.
For some unknown reason different
parts Of the tongue are assigned for
the perception of different tastes.
With the tip we taste sweet substances
and salts, with the back we taste bitter
things and with the sides we taste
acids. The middle part of the tongue
surface has scarcely any sense Of taste
at all.
The long named substance parabrom-
benzoic sulphinide produces most re-
markable effect. for it gives a sense OF
sweetness to the point OF the tongue
and of bitterness to the back. Pure
water tastes sweet after sulphate Of
magnesia.
We can only taste things in solu-
ton: hence if the tongue were perfect
" dry it would not be affected by the
strongest favored substance in dry
state.
The taste nerves are paralyZed by
very hot or very cold liquids. After
drinking very hot or ice cold water
we, could not taste even such sub
stance as QuiDine. This fact supplies
Il useful hint for consumers of i'll IA
vored medicines. ....
Smell though the least useful, is the
-cost delicate of all our senses. We
can smell the hree-hundred- mi!liOnth
part Of grain of musk, No chemical
analysis can detect such minute guam
titles. The most powerful microscope
would not render a particle ten thou
, sand times as large visible. We could
not taste it were it many Thousand
times as large. ..- ,,r
While we taste liquids, we can smell!
only gases. Fill your nostrils with eau
de cologne. and you will experiences no
'odor whatever. Fine as our sense Of
smell is. it has deteriorated immensely
since the time when our forefathers
were wild men. The. Calmucks, can

The organ Of hearing is one Of the
most marvellous pieces of mocha nism
in the body. In animals the external
ear acts as a trumpet to collect the
sound waves; In man ii is little more
than an ornament. but the Internal ear
is alike in both, So wonderful Is its
construction that We can distinguish
sounds varying from forty to 1900 vi
brations per second. This feat is per
formed by portion OF the ear called
the organ of Certi. What a wonderful
organ that is may be understood from
the fact that it consists of 5000 pieces
Of apparatus. each piece being made
up OF two rods. one inner hair eeil and
iour outer hair cells-that u.s. 50, $50

which feel only pressure and spots
which feel tickling. These spots are
