The most complete anatomical examination of cases of Siderosis bulbi has been made by E. v. Hippel; lUnige, and Bednarski (9) have also examined a number of eyes with siderosis of xenogenic origin. My own interest in the subject was aroused by cases which I saw long before the sideroscope was invented and the Roentgen ray was made available for the location of foreign bodies in the eye. Since then I have been constantly on the lookout for such cases and it has been my fortune to see a good many of them. I have seen a number of cases on which the cornea wa^ stained brownish for some distance around a fragment of iron which had been lodged in it for weeks, but I have never seen staining of this membrane from iron located in the lens O deeper in the e3'e. Bunge has reported two cases of siderosi^ cornea. The fragment of iron was situated in the nasal ora serrata, Hirchberg (10) saw 2 1-2 years after a fragment of iron Jiad entered the eye, a deposit of yellow dots on the posterior sur- face of the cornea. Praun (11) has reported a case in which a large splinter of iron had remained for a year in the center of the cornea causing a ring of rustbrown color 2 mm. in diameter which was surrounded by a somewhat lighter ring of 5 mm. in <liameter. The change in the color of the iris mentioned by other ob- servers I have seen onl}^ in cases in which the yellowish brown -dots arrajnged in the form of a wreath under the anterior ■capsules of the lens, were present at the same time. I have seen both a yellowish brown and a greenish yellow discoloration, but the first most frequently. The eyes showing this discoloration -of the iris had in all my cases harbored the fragment of iron more than six months. I may say right here that in all of the -cases on which these remarks are founded the fragment of iron Avas either extracted by means of the magnet or the iron was found in the enucleated eyeball. The discoloration of the iris due to xegoneous siderosis has been seen to disappear again and the •original color restored after the removal of the iron (Hirschberg '(12)), and even in cases in which the iron remained in the eye (Vossius (15)). In my own cases the discoloration remained in all cases after the extraction of the iron as long as they were tinder observation. It is well-known that a similar discolora-
