We have Instances of Abortions by the way of the Mouth,the Anus, the Navel, &c. See FOETUS, EMBRYO, &c.
The usual Causes of Abortion, are immoderate Evacuations, violent Motions, sudden Passions, Frights, &c. OtherCautes are the largeness and heaviness of the Fœtus, Irritations of the Womb, Relaxation of the Ligaments of the Placenta, Weakness, and want of Nourishment in the Fœtus ;excess of eating, long fasting or waking, the use of Busks forthe Shape, offensive Smells, violent Purgatives; and, in thegeneral, any thing that tends to promote the Menses.
The Symptoms usually preceding, are a Fever, eithercontinual or intermitting; Pain in the Loins and Head, heaviness in the Eyes, a bearing down and Constriction of theAbdomen. When the Time of Miscarriage is just at hand,the Pains are much the same as those in Labour. See DELIVERY.
