and of the uterus by the horns of cattle had resulted in the delivery of a living child. He published a paper in the American Journal of Obstetrics (1887), entitled "Laceration of the Abdomen and Uterus in Pregnant Women," which gave nine cases of cow-horn delivery with five living children, and in 1892 another "Abdominal and Uterine Tolerance in Pregnant Women," giving eleven more cases— "a better showing for the cow horn than the knife," as he remarked.
Another valuable statistical object was collecting the fate of all the viable extrauterine children. A statistical paper on "Ectopic Gestation" involved him in an imbroglio with Lawson Tait who called him "a library surgeon." This paper was translated into German by A. Eidman of Frankfürt-on-Main and appeared in the Monatschrift für Geburtshülfe und Gynäkologie for August, 1897. Many of the editorials in the Medical News (Philadelphia) were from his pen. He took up Loretta's operation for divulsion of the pylorus. He edited "Playfair's Midwifery" in this country for Lea Brothers. The last article he wrote, "Congenital Absence of the Penis with the Urethra making its Exit into or below the Rectum," appeared in the Philadelphia Medical Journal for January, 1893.
In February of 1899 he had a second stroke of paralysis following one in 1895, and he died after a few days' illness in his seventy-seventh year. His income was always rather slender and he never married or kept a house but boarded out.
Besides his private value as a firm friend and Christian he is entitled to great respect and admiration as a man who investigated knowledge accumulated in the past and placed all that was valuable in it at the service of others.
