After careful consideration of the gravity of the situation it was determined not to proceed with the removal of the small and probable osteoma, but to seek further information from carefully prepared x-ray examinations and the disclosures of future observations. The septum orbitale and external wound were securely closed and the conjunctival sac sutured, and his recovery was speedy and uneventful. A NOTE ON THE RELATION OF SEX LINKAGE TO CERTAIN HEREDITARY DISEASES OF THE EYES. LUCIEN HOWE, M.D., Buffalo, N. Y. Our ignorance of heredity as a factor in diseases of the eyes is too well known to require more than mention. Thus far ophthalmologists, like other members of the medical profession, have been content simply to record family histories in which certain deformities or diseases seem to be hereditary. But the time is approaching when we are able to classify at least some of these anomalous conditions. That classification will give us a clue as to what may be expected in certain lines of descent, and consequently what we should say when a person asks as to the advisability of marrying into a family in which a certain disease has appeared with suspicious frequency. Our information concerning this subject will apparently come not from ophthalmologists, but from geneticists. Their many experiments in breeding show two things: First, that the Mendelian law in its simple form applies even to peculiarities of the eye. Second, the geneticists have also shown that certain imperfections of the eyes do not follow the Mendelian law, as that was first stated, but a given abnormal condition may show itself preferably either in the male or in the female descendants. For this reason it has been called "sexlinked." Many interesting and instructive experiments have been ...
