When the complaint resists such remedies, or when, from its degree, it may appear unnecessary to employ them, the only relief which can be afforded, unless the womb become pregnant, is to be obtained by wearing an instrument called a pessary. It is made of wood or ivory, and if properly adapted to the passage, and of a proper construction, it can be worn without much inconvenience, and it never occasions pain. Certain attentions are however necessary, whenever such an instrument is used. Thus, the pessary should never be allowed to remain in the passage above a few days at a time, otherwise it becomes the source of great irritation. It should, therefore, be occasionally withdrawn on going to bed, well cleaned and reintroduced in the morning, before the patient rises. In some instances, after a pessary of a certain size has been worn for several months, one of a smaller size becomes better adapted to the passages, and in other cases one of a larger size is required. Sponges of such a size as, when expanded, fill up the cavity of the vagina, are very good _pessaries_. They support the uterus, and, by putting a string through them, the end of which is to be left hanging out of the os externum, the woman can take them away and apply them herself very conveniently. To answer this purpose, a fine sponge, wrung out in alum water, may be dried in a compressed state, and cut into any convenient form, so as to be introduced as high as possible: this will act by its astringency, and by its pressure, in a gentle and uniform manner. During the use of this application, an astringent injection may be used twice a day; and the sponge tent should be made gradually smaller as the vagina contracts. The application of the bandage round the whole belly, with a moderate degree of firmness, often gives great relief to the uneasy feelings. The T bandage has also been worn in this case with considerable advantage. If a woman liable to falling down of the womb, become pregnant, there is no occasion for the pessary after the third month, and by proper treatment after delivery, the return of the complaint may be prevented. MISCARRIAGE OR ABORTION. We now come to the consideration of a subject, in respect to which there exists much misapprehension and ignorance, causing useless and unnecessary alarm and anxiety to those who may be so unfortunate as to be subject, at particular periods of gestation, to abortion or miscarriage.
