Why is the Eye-ball White ?
This portion of the eye contains a high percentage of blood, and why therefore is it white ? The answer most recently given is that the blood-vessels which supply its surface are so exceedingly minute that usually they do not admit the little red corpuscles to which the ordinary red appearance of the blood is duo.- Blood without these corpuscles is colourless, or, at most, of the faintest yellow tiut. But occasionally, when the eye is irritated, as by a spec of dirt or otherwise, or when there is any slight or considerable derangement of the system, certain of the little vessels enlarge sufficiently to allow the corpuscles to enter, thereby producing the well-known red streaks or inflamed appearance of the eye-ball, generally described as ' bloodshot.'
