shuffles along, endeavoring ‘‘to feel” his way. The horny hoof lacks 
the human faculty, but the horse endeavors to surmount objects by step- 
ping high. A blind man turns the sightless face heavenward; the 
animal, likewise, raises its head, as it were, to expose its sightless orbs 
to its Creator. There is another strange peculiarity also, exemplified 
by the blind horse. The sightless quadruped, contrary to the majority 
of its species, generaily carries a rough coat in summer and a blooming 
coat in winter. 
Now, a high stepper, a well-carried head, a lively ear, and a blooming 
coat, are great points in a horse, especially about London, and with 
gentlemen of little information. To prevent imposition, always place 
the horse in a full light. Should the pupils continue large, have the 
horse put into a dark house. A quarter of an hour afterward, take a 
candle, and by its light regard the eye. If the pupil is still dilated, 
hold the candle near to the eye. The iris will not contract quickly upon 
artificial light, but in five minutes it ought to move. However, suppose 
you imagine it to remain stationary; then, 
placing yourself by the head, have the 
horse led out into sunshine. If it exhibit 
no change to mark the passage from dark- 
ness to daylight you may certainly con- 
clude the optic nerve is paralyzed. 
There are other tests, but these are not 
satisfactory ; such as covering the eye with 
the hand or a hat. The hand is semi- 
transparent, and so can only induce par- 
tial darkness; the hat does not fit the 
inequalities of the horse’s countenance, 
therefore it is useless. Of the same nature 
is aiming pretended blows at, or moving 
the hand before, the suspected eye. The 
other senses, by constant exercise, become 
so very acute during loss of sight, that
