with numerous concentric grooves.

"And this" said he. ''is weak solu-

one of the eyestones and placed II in

and supersutious people to the notion
that 1t has life and that 1t loves vine

on the vessels enga ged in the fruit
trade with those regions obtain the
stones from the natives and bring
them here for sale to the wholesale
druggists, and there was time when
the demand for them generally was
quite large.
There is nothing better to remove
foreign substances from the eye than
one Of these South American eye
stones, which use Is what gives them
their name. Many people think that
before using them 1t is necessary to
put them In vinegar to give them
life but 1t is not necessary at all
The stone Is inserted at one corner of
the eye, with the grooved side next to
the lid. The pressure OF the eyeball
forces it to move about in the eye, and
the grooves collect the foreign matter
and retain it. After making a thor
ough circuit of the eye the stone will
come out at the corner next to the
nose. No Inconvenience is caused by
its presence
'There are other eyestones. In the
head of our common crawtish there
are two little bones. just back Of and
beneath the eyes, which resemble the
South American eyestones. about the
only difference being that they are
smooth all over instead of grooved on
one side. These crawish bones are
known as eyestones and are used as
such 10 the west. but they have none
Of the virtues of the real eyestone.
Their proper name is crab stones. In
Poland and parts of Russia quite a
trade is found in the collecting of
these crab stones. The crawfish are
taken and buried in deep pits. where
they are left to die and rot. The refuse
is then washed and the stones are
picked out They are not used in
those countries as eyestones. but are
taken internally, faith in their benefi-
cent stomachlc properties being great.
