BLINDNESS, in farriery. When a horse becomes blind, it may be thus discerned: His walk or step is always uncertain and unequal, so that he does not set down his feet boldly when led in one's hand: But if the same horse be mounted by an expert horseman, and if he be a beast of metal, then the fear of the spurs will make him go resolutely and freely; so that his blindness can hardly be perceived.
