Galen defines Cicatrices and Albugo of the eye as follows:—“Cicatrix appellatur ubi nigro oculi ex alto ulcere membranae crassities supervenit, ut color albior apparet. Albugo nihil a cicatrice differt, nisi quod ex ulcere major cicatrix simul et crassior in iride nascitur.”—Kühn’s Edit. vol. xiii. p. 775.
