of the horse, dooms it to a lower class of proprietors, and takes from 
the creature’s life much of the pleasure which otherwise might lighten 
the animal’s existence, 
After death, an anatomical peculiarity is observed. The optic nerves, 
subsequent to leaving the brain, unite and exchange fibers. Neither 
nerve pursues an absolute course; yet, consequent on decease, if the 
right eye were blind from gutta serena, the left nerve, or the nerve 
originating from the left side of the brain, alone is affected: the disease 
seems confined to that part. The opposite nerve is perfectly white and 
healthy; but the one affected with paralysis is of a yellowish color, 
softer nature, and sensibly diminished in bulk. So, if blindness afflict 
both eyes, both optic nerves are then of diminished size and of a yel- 
lowish hue.
