The causes of interrupted pregnancy may be placed in three classes. The maternal causes are divisible into systemic and the local. The systemic causes include obesity, marriages of consanguinity, _pregnancies in rapid succession_, etc., and the toxemia of kidney insufficiency. The local causes include all cases of acute and chronic pelvic congestion. P. 332. Chief among the paternal causes is syphilis, tuberculosis, extreme youth or old age, great constitutional depression, exhaustion from any cause. P. 333. _MEDICAL GYNECOLOGY.

Appleton & Co., New York and London, 1912._ The susceptibility of syphilis to hereditary transmission is a fundamental character of the disease. It may be transmitted to the offspring directly by the infected sperm of the father, or from the infected ovule of the mother at the time of impregnation, or the infective principle may be conveyed through the medium of the utero-placental circulation during the course of pregnancy. P. 432. Whether the infection is communicated through the sperm solely, the ovule, or the utero-placental circulation, the uterine death of the fetus is the most habitual expression of hereditary syphilis. Hereditary syphilis is one of the most common causes of abortion. P. 434. Clinical observation shows most conclusively that certain dystrophies and organic defects in the subjects of hereditary syphilis may be transmitted to the third generation. P. 436. While we cannot conclude that syphilis is transmitted in its essential nature as a virulent contagious disease, to the third generation, yet it is well known that heredo-syphilis kills the product of conception, or transmits to the survivor an impaired vitality with various dystrophies, and thus constitutes a chief factor in the physical, mental and moral degeneration of the race. From an exhaustive study of heredo-syphilis, Tarnowsky concludes that syphilis has an incomparably more fatal influence upon the species and on society than on the individual. P. 437. _PRINCE A.
