Sexual Problems of Today BY WILLIAM J. ROBINSON, M.D. In this book the scientific knowledge of a physician, eminent as a specialist in everything pertaining to the physiological and medical side of these topics, is combined with the vigorous social views of a thinker who has radical ideas and is not afraid to give them outspoken expression. A few of the subjects which the author discusses in trenchant fashion are: The Relation Between the Sexes and Man's Inhumanity to Woman.- "SEXUAL PROBLEMS OF TODAY" will give most of its readers information they never possessed before and ideas they never had before— or if they had, never heard them publicly expressed before.

Price, Only Ten Dollars FOR OR several years we have marketed a standard pituitary extract under the name of "Pituitrin." The product is prepared from the posterior lobe of the pituitary gland and has come into extensive use in delayed parturition due to uterine inertia. Being specifically intended for use in obstetrical work, this preparation will hereafter be called PITUITRIN O. -(Pituitrin obstetrical). Administered hypodermatically in properly selected cases, in the second stage of parturition, it stimulates uterine contraction, hastens delivery, prevents needless suffering of the mother, and diminishes the risk to the child which attends upon protracted labor. We now announce a second preparation of the pituitary gland, to be known as PITUITRIN S. -(Pituitrin surgical). This product is intended specifically for use in the treatment of post-operative intestinal paresis, vesical atony, hemorrhage, shock, etc. Pituitrin S. is twice the strength of Pituitrin O. Because of its exceptional potency it should not be used in obstetrical practice. To readily distinguish it from Pituitrin O. (obstetrical), the carton labels of Pituitrin S. (surgical) are printed with red letters on white paper. PITUITRIN O.: Ampoules of 1 mil (1 Cc.) and 1⁄2 mil (1⁄2 Cc.); PITUITRIN S.: Ampoules of 1 mil (1 Cc.) only.
