That is an absurd assertion. Many wcarers
buy two or three eyes at one time, so as to
have them on hand in case of accident, and
some have two i'll regular 60 for the

yes; the trouble is they generally cry a
great deal more from the unnatural irrita-

very much on the state of the health of the

The artificial eye is made from a bulb of
glass blown, having a slight ovality, on the
end OF 4 rod of glass about the size of a
pencil. From the sphere thus blown a
segment is cut which is fiattened out at the
place for the iris and the pupil and a cir
cuIar patch of black pigment in the center
forms the pupil. The painting of the iris
IS done with very delicate enamel colors

William Siemens devised an artificial
eye which is sensible to light
and to differences in color, gives
signs of fatigue when subjected to pro-
longed action of light, and regains it's
strength after resting with closed lid; Nod,
by an electro-magnet attachment, may be
made to close itself involuntarily at a vivid
flash" Such an eye would be worth hav-
ing. 1t is well known, too, that the vibra-
tons OF musical tones may by ordinary con-
Quoting wires be transmitted and delivered
to the ear, and it remains to be seem" saws
DR.. SiemenS, whether light vibrations
may not be transmitted to the brain in the
absence OF the natural eye"
1T is a curious fact that the demand used
to be all for dark eyes, but the sale of
these has been dying out, and now the mar
ket has to supply a constantly-increasing
call for light eyes, the proportion being
eighteen or twenty to one in favor of the
light eye. This is not u freak of fashion.
but may be traced to the actual increase OF
light, genuine eyes, through the influx OF
population from Northern Europe. Prob
ably over 10, 900 people in the United States
are wearing artificial eyes to-day.
