[handwritten] 2 Chapter I. Introductory [obscured] The object of the present memoir is to give some account of Albinism in Man. Its scope is not only historical and bibliographical; we wish further to put before the reader a considerable map of new material which has been directly collected for the purposes of this inquiry and which is we believe more ample than any yet provided. It allows for the first time of statistical conclusions being drawn as to the nature and heredity of albinism. As far as we are aware no very full treatment of the subject has been undertaken since the classical memoirs of Cornaz[sp?][superior symbol], and these while they provide very full references to the albinistic literature at his date are now a half a century old and the new material then contained in them while very full of the stocks with which Cornaz[sp?] dealt is limited to but two or three stocks. A more numerous series of families has been considered by Arcoles[[superior symbol], but beyond the statement that the parents were in all cases normal, Arcole's memoir deals simply with the sibship[superior symbol 's'] of the albino, and leaves unconsidered the family history of albinism in other ascendants, descendants and collaterals, which we have almost invariably discovered, where it has been possible to trace the stock with any degree of genealogical [fullness?].
