why Do Cats Eyes Shine In the Dark
While Mems Eyes Do Not?
Why do cats eyes shine in the dark
while mems eyes do not? The author of
idle Days In Patagonia" raises this
question without answering it. He shot
and wounded an eagle owl, and the sight
of the bird, he says, was one of the
greatest surprises with which nature
ever favored him. The owls haunt was
an island overgrown with grass and tall
willows. Thither Mr.. Hudson went to-
ward evening and found him upon his
perch waiting for sunset. He eyed the
intruder so calmly as almost to disarm
him, but hunters Of specimens have a
way of hardening their hearts. Mr..
Hudson fired The owl swerved on his
perch, remained suspended for a few mo-
ments and then slowly futtered down.
He says:
found my victim stung to Sury by
his wounds and ready for the last SUI
preme effort. Even in repose he is big,
eaglelike bird; now in the uncertain
light he looked gigantic in size-a mon
ster of strange form and terrible aspect.
Each particular feather stood on end,
the tawny barred tail spread out like
fan, the immense tiger colored wings
wide open and rigid, so that as the bird,
that had clutched the grass with his
great feathered claws, swayed slowly
from side to side-just as snake about
to strike sways his head, or as an angry,
watchful cat moves its tail-first the tip
of one, then of the other wing touched
the ground.
The black horns stood erect, while in
the center of the wheel shaped head the
beak snapped necessarily, producing
sound like the clicking of a sewing ma
chine. This was a suitable setting for
the pair of magnificent, furious eyes, on
which gazed with kind of fascination,
not unmixed with fear, when remem-

casions from sharp, crooked talons driv-

The irides were of bright orange
color, but every time attempted to ap-
proach the bird they kindled into great
globes of quivering yellow fame, the
black pupils being surrounded by scin-
tillating crimson light which threw out
minute yellow sparks into the air. When

raj fiery aspect would instantly vanish.
The question as to the cause of this
fiery appearance is one hard to answer.
We know that the source of the lumi-

rejecting membrane between the retina
and the sclerotic coat of the eyeban, but
the mystery remains. When with the
bird, I particularly noticed that every

obscure them for some time, as they will

sunlight, and this gave me theimpression
that the fiery, flashing appearance was
