    Pigs. 1 and 2.—The appearances of Sclerotic and Conjunc¬ tival Inflammation contrasted. Pigs. 3 and 4.—Diagrams explanatory of the course of the vessels in each disease. Pig. 5.—Operation for Artificial Pupil, rendered necessary by opacity of the cornea in the axis of vision: a needle has been passed through the cornea, by the curved point of which the ciliary connection of the iris has been torn away, and an artificial pupil thus formed through a part of its circumference. [To display the position of the needle, the corneal opacity has been only partially represented.] Pig. 6.—Another mode of making an opening through the iris, where the pupil is closed, but the cornea remains trans¬ parent : it consists in passing a needle with cutting edges through the sclerotic; carrying the point through the iris into the anterior chamber; and then making an incised wound through the iris, to admit the passage of light to the retina. Pig. 7.—True Pterygium, distinguished by its triangular form from Pterygium Pinque, Pig. 8.
