Chlorosis.--Chlorosis is that form of anemia, of poor blood, which occurs in young girls about the time their sickness begins. It is most frequently seen between the fourteenth and seventeenth years, and more often in blondes than in brunettes. The cause is not known. It is thought to be due to constipation. Any occupation which is deleterious to health has a distinct influence on the condition. Employment in factories, confinement in badly ventilated rooms, bad or insufficient food, great grief, care, or a bad fright, mental strain, overstudy, may all produce, or contribute to the production of chlorosis. Symptoms.--The symptoms of chlorosis resemble those of simple anemia. Children suffering from anemia are pale; girls with chlorosis have a peculiar greenish yellow tint in the skin. They are short of breath, they have vertigo, palpitation, disturbances of digestion, constipation, cold hands and feet, and scanty or arrested monthly periods. They have various nervous disturbances, such as headache, pains in various parts of the body, neuralgia, especially over the eyes, hysterical attacks, and sometimes cholera. Ulcer of the stomach is sometimes seen in this condition. The disease lasts for a year or longer; it frequently lasts a number of years. Relapses are frequent. [Illustration: By permission of Henry H. Goddard "A Misfortune at Birth"] Warren is feeble-minded. His family said it was due to "a serious fall of the mother." [A]"The family history is, however, exceedingly interesting. "The paternal grandfather, whom we have called Nick, was of good family, although he himself was totally different from the rest. He was weak in every way, and to be considered feeble-minded. He married into a family that was much lower socially than his own, although we have no proof that it was a defective family. The children of this couple were all mentally defective and low-grade, morally as well as intellectually. "Warren's father, Jake, a thoroughly disgraceful character, married Sal, a woman somewhat older than he. "The immorality of this family beggars description. A girl named Moll was fifteen years old when Jake brought her into his home: his wife, Sal, was so feeble-minded that she allowed the illicit relations between these two. Moll's child was born in the hospital after the mother had been sent away from one Home because of her horrible syphilitic condition--from which she finally died. "Our boy Warren's sister Liz with whom the father lived in incestuous relations, was also allowed to live illicitly with a man who worked for her father. She was so simple that she talked openly about her relations with her father and with this man. When a child was to be born the man married her. "This is not all, but enough: and sufficient to show what feeble-mindedness leads to when it takes the direction of sexual abuses."
