1. The giving birth to an embryo or non-viable fetus. 2. The product of such premature birth. 3. The arrest of any action or process before its normal completion, as the abortion of pneumonia. A distinction is sometimes made between abortion and miscarriage, the former signifying the emptying of the uterus prior to the fourth month of pregnancy, the latter during the fourth, fifth, or sixth month; premature delivery noting the delivery of a viable fetus after the beginning of the seventh month and before full term.

The expulsion of the foetus before the seventh month of utero-gestation, or before it is viable. The causes of this accident are referable either to the mother, and particularly to the uterus; or to the foetus and its dependencies. The causes, in the mother, may be :-extreme nervous susceptibility, great debility, plethora, faulty conformation, &c.; and it is frequently induced immediately by intense mental emotion, violent exercise, &c. The causes seated in the foetus are its death, rupture of the membranes, &c. It most frequently occurs between the 8th and 12th weeks of gestation. The symptoms of abortion are :-uterine hemorrhage with or without flakes of decidua, with intermitting pain. When abortion has once taken place, it is extremely apt to recur in subsequent pregnancies about the same period. Some writers have called abortion, when it occurs prior to three months, Effluxion. The treatment must vary according to the constitution of the patient and the causes giving rise to it. In all cases, the horizontal posture and perfect quietude are indispensable.
By Robley Dunglison
Premature arrest of a morbid or a natural process. Abortion is termed accidental or spontaneous, when due to accident; artificial or induced, when brought on purposely; criminal, when not necessary for therapeutic reasons; embryonic, when it occurs before the fourth month; fetal, when after the fourth month; habitual, when repeated in successive pregnancies; incomplete, when the placenta is retained; inevitable, when the embryo is dead or there is rupture of the ovum; missed, when the fetus is dead, but is not expelled within two weeks; ovular, when occurring within the first three weeks.
