In the course of pregnancy, during the latter months particularly, the feet and legs frequently become much enlarged. It is partly owing to the pressure of the womb, but sometimes apparently independent of it. It is first observed towards night, about the ankles; by degrees the swelling rises higher, and the legs may become of a very large size. The female suffering from this complaint, always goes to bed with legs much swollen, but towards morning her face swells, and the enlargement of the legs disappears to a greater or less extent, returning, however, as the day advances. Sometimes this disease is very trifling in its character, and in ordinary cases, except aperients, no medicine is necessary, and support may be given by a well-applied flannel roller; but when the swelling is extensive and permanent, remaining in the same degree after the patient has been for several hours in bed, and connected with uncomfortable sensations in the head, an accelerated pulse, &c., a medical man ought to be consulted, for the consequences might otherwise be dangerous. _Palpitation of the Heart._ If this affection occur for the first time during pregnancy, it is rarely connected with disease of the heart itself; it is therefore without danger, although very distressing. Occasionally there is connected with it throbbing of the vessels in the temples, as also in the abdomen; the latter not unfrequently mistaken by the patient for the beatings of the heart itself. It will make its attack repeatedly in the course of a day, particularly after a meal; and very frequently at night, on first lying down in bed; and it may be brought on at any time by the slightest agitation of mind.
