    looked. If tlie intruder was a spicule of hot iron, the brown spot which often remains (see Plate 21) must be .carefully scraped out (a matter of some difficulty during the first few days, as the substance clings tenaciously), Atropin is not necessary in fresh, non-inflammatory cases ; but a compressing bandage is always to be applied and kept on until the reflex has become normal, or at least until the site of the injury becomes covered with epithe- lium and fails to take the fluorescin stain. If this pre- caution is neglected, a protracted case of diffuse or hypo- pyon-keratitis is apt to result. Large wounds of the cornea, especially perforating wounds, must also be dressed with a compressing bandage, and the ])atient must be jnit to bed. In ease of prolapse of the iris, if the injury is quite fresh, re})lacement with a suitable instrument (s})atula) may be attempted, after disinfecting with a 1 ; 5000 sublimate solution. The operation is usually a failure. If the prolapse is one or two days old, infection has very probably taken place, and replacement would be followed by a dangerous iritis which would imperil the other eye. In such a case it is better, therefore, to excise the prolapsed iris, rej)lacing only the ciliary attachments, so as to leave as little iris-tissue as possible in the wound and relieve the tension of the pujDil. MALFORMATIONS OF THE CORNEA. These are of interest because they interfere with vision. The mo.st frequent anomaly is unequal horizontal and vertical curvature, and forms one of the causes of astig- matism. Megalocornea {cornea r/lohosa) may be congenital and sometimes hereditary ; the cornea may retain its trans- parency throughout the life of the individual. A similar anomaly occurs after infantile glaucoma ; but the cornea in this form early presents the characteristic glaucomatous haze and later becomes covered Avith irregular opacities which materially impair its transparency. The bulb
