    Reprinted from Ihe Royal London Ophthalmic Hospital Reports, Vol.XT'ir, Part I. ON KETINITTS PIGMENTOSA AND ALLIED DISEASES. By E. Nettleship. The diseases noticed in the present paper are retinitis pigmentosa (including the so-called retinitis pigmentosa sine pigmento), retinitis punctata albescens (Mooren and Gayet), atrophia gyrata choroideae et retinae (Fuchs), and congenital stationary night-blindness without changes. Whether the last-named disease is of the same essential nature as retinitis pigmentosa or not, the two conditions are so much alike in their symptoms and natural history that they may con- veniently he considered side by side. My principal object has been to appraise the share taken by heredity and consanguinity in causing these maladies, and especially to ask whether blood-relationship carries any influence at all, apart from the existence of a predisposition to the disease in the two consanguineous parents or ancestors. I have, therefore, analysed all ihe published cases I could get access to, adding my own (about 100) and some other unpublished ones placed at my disposal by friends.* The result is a series of nearly one thousand families, containing about seventeen hundred persons affected with retinitis pigmentosa, and upwards of fifty families, containing nearly three hundred individuals aflected with some one of the other three diseases. By “family ” I mean * Mr. Marcus Gunn, Mr. Lawford, Dr. E. J. Smyth, Professor La Gleyze of Buenos Ayres (through Dr. Mackenzie Davidson), and others. b
