196 EXPRESSION IN THE ANIMAL EYE 
plete contrast to the vapid effect of red eyes in most 
animal faces. We believe that the countenance of 
a pink-eyed albino guinea-pig is as nearly devoid 
of expression as it is possible for the face of a quad- 
ruped to be ; and whenever the pink eye accompanies 
albinism there is an obvious loss of interest in the 
face, though the eye, considered as an object apart, 
may have the depth and lustre of a smooth garnet. 
Where albinism develops blue eyes, as in white 
cats, and sometimes in white horses, the loss of ex- 
pression is less ; but even in the horse, the blue eye, 
ringed with pinkish-white, is too like that of fish 
to suggest a tenth part of the intelligence and power 
of emotion latent in the face of the dark-eyed Arabian. 
Even dogs with light eyes have less of the appearance 
of truth and trustfulness than others, though the 
pale eye is seen in some of the most ancient and 
valuable breeds, such as the lemon-and-white Clumber 
spaniel. In the case of the dog, the human preference 
for the dark over the light eye is perhaps explained 
by the affinity which the last has with that of the 
wolf and the common fox. The cunning, shifty 
look which the last animal possesses, is largely due 
not only to the yellow colour, but also to the shape 
and mechanism of the vulpine eyes. They are set 
close together, and the inner corners run down almost 
parallel to the muzzle. In addition, the pupil of 
the fox’s eye expands and contracts like that of a 
cat . 1 By day the eye is a mere yellow orb, with a
