    CHAPTER XIX DOES A DISEASED OVARY LEAD TO DISEASED CHILDREN? It is a remarkable fact that in many families containing both boys and girls we hnd that all the children of one or other sex are in some way or other affected: they may be physically affected or deformed, or else mentally deficient; while the children of the other sex are quite normal. The following cases of insanity are very remarkable, and are more than coincidences: Mrs. W. had 5 children, thus: ist a boy, 2nd a girl, 3rd a girl, 4th a boy, 5th a boy. The three sons are all mentally very deficient, two are idiotic, and one quite insane. The two girls are quite sane. Mrs. P. had 5 children: ist a boy, 2nd a boy, 3rd a girl, 4th a boy, 5th a boy. The four sons are healthy and quite sane. The daughter is an idiot. Mrs. S. had 3 children: ist a boy, 2nd a girl, 3rd a boy. The two sons are insane; the girl is quite sane. Note that the unhealthy or abnormal children do not follow each other; the birth of normal children of the oppo- site sex takes place between them. The following remarkably conhrmatory case I take from the “ Lancet,’' June 7, 1902: Drs. Keraval and Raviart report a case of insanity in twin brothers who had for many years lived quite apart from one another. The mother of the men was alive and well. Neither men had had syphilis, and both were temperate in their habits. Both were married. The special interest of the case lies in— (1) The twinship of the brothers. (2) The absence of hereditary antecedents of insanity. (3) The freedom from syphilis and alcoholism. (4) The fact that both were married and fathers of children.
