In some instances the evacuation is impeded by a mechanical cause, that is an obstruction of the passage to the womb. This occasionally is met with, and the chief obstacle to its speedy removal is the difficulty of ascertaining its existence. The operation by which it is completely remedied, is not more painful nor formidable than blood-letting.

Fortunately, in most cases, the evacuation takes place in due time, and the constitution sustains no material or permanent injury. It is, however, in every instance, proper to pay particular attention to the system during the continuance of the evacuation.

The stomach and bowels, at this period, are very easily disordered, and therefore, everything which is heavy or indigestible, ought to be avoided. Some are hurt by eating fruits or vegetables; others by taking fermented liquor. In this respect experience must enable each individual to judge for herself. Exposure to cold, particularly getting the feet wet, is hurtful, as it tends suddenly to obstruct the discharge. The same effect is likewise produced by violent passions of the mind, which are also, at this time, peculiarly apt to excite spasmodic affections, or hysterical fits.

It is, in general, a very proper rule not to administer any very active medicines, at this time, unless some violent symptom absolutely requires them. Opiates, for instance, are, in many cases, necessary to allay spasmodic affections, or abate pain; and they are, in such circumstances, uniformly safe. They give speedy relief to hysterical feeling or suffocation, or to spasm of the stomach or bowels.

Dancing, exposure to much heat, or making any great or fatiguing exertion, are improper. These causes may increase, to an improper degree, the quantity of the evacuation, and in certain circumstances may give a disposition to a falling down of the womb.

RETENTION OF THE MENSES.

Description.

The menstrual discharge is liable, from many causes, to become obstructed at the period when it ought to appear; when this takes place it is attended with very painful or serious effects; and, if nature is not assisted, the health is impaired or the constitution undermined, inducing consumption or some other complaint.

Causes.

The remote cause of this complaint is most frequently suppressed perspiration; and it may arise, in part, from an inactive sedentary life, and such habits as are peculiar to the higher classes of society, particularly in cities and towns. The proximate cause of it seems to be a want of power in the system, arising from inability to propel the blood into the uterine vessels with sufficient force to open their extremities and to allow a discharge of blood from them.
