Abortion (ab-or'-shuti) [abortus, a miscarriage]. The 

 premature expulsion of the ovum before the child is 

 viable, that is, occurring any time before the end of the 

 sixth month. It may be produced by various general 



. diseases, as syphilis, the acute fevers, nephritis, most 

 exhausting diseases ; by traumatism, reflex influences, 

 emotional disturbances ; by the action of various poisons, 

 as ergot, cantharides, rue, and savin; by diseased con- 

 ditions of the uterus and displacements of that organ ; or 

 by diseases of the fetus, its membranes, or the placenta. 

 The most important symptoms are hemorrhage and 

 pain, with final expulsion of the uterine contents. In 

 the first two months of pregnancy the ovum is usually 

 expelled entire ; later the membranes and placenta are 

 retained after the fetus comes away, and must be re- 

 moved subsequently. By some authors expulsion of 

 the ovum during the first three months is abortion ; 

 from this time to viability it is termed immature de- 

 livery, or miscarriage, and from the period of viability 

 to that of maturity, premature delivery. A., Arti-
