fall immediately after delivery, and so drives the perspirable matter within, and causes inflammation and suppuration. A difficult or prolonged labor may also lead to it, by preventing, for a long time, the proper circulation of the blood through the large veins of the pelvis, and so engorging those below. Or the veins may become paralyzed, as it were, by the pressure they have sustained, and so become, for a time, unable to transmit the blood. In fact, both the veins and lymphatics become engorged, as if tied above the limb, and exhibit knots and bundles, like bunches of grapes. Sometimes the fever will occur some days first, and the female cannot tell what it is owing to, till the swelling comes on; and even this may take place so gradually, and with so little pain, that the limb may be very large before it is observed. I have known females complain of a slight fever only, on going to sleep at night, and wake up in the morning with a confirmed case of milk leg; and I have known others start with a sudden pain in the groin, or hip, and be affected in the same way, in less than two hours. The disease usually lasts from a month to seven or eight weeks, and terminates, either by a gradual resolution, or scattering, of the fluids, or by suppuration and discharge. When suppuration ensues, there will, sometimes, form one or more very large abscesses, which it may be difficult to heal, and which may lead to serious results, either from their extent, or from the constitutional irritation they produce. The treatment, at first, consists in warm fomentations, such as those of poppy-heads, or hops, with cooling drinks, purgatives, low unstimulating diet, and occasional doses of James's Fever Powder, to promote perspiration. This is intended to disperse the swelling, and, in general, it does so. If, however, the abscess forms and breaks, in spite of all the means used, it must be treated the same as abscess in the breast, previously described. In ordinary practice, it is the general custom to _bleed_ at the commencement of the disease, or to apply leeches to the groin. This sometimes does good, but frequently is of no service at all, even if it does not make matters worse. I would, however, make the same remarks on bleeding here, as I did in regard to its use in _puerperal fever_, to which milk leg has a resemblance, in some respects. Another practice is to use tight bandages, the same as for varicose veins, but I think the plan is not, in general, a successful one, though it may be occasionally. Plunging the limb in cold water, or keeping it wrapped in cold wet cloths, has succeeded much more frequently, and is, with some, a favorite remedy. Stramonium leaves boiled in vinegar, and laid on hot, will also effect a cure sometimes; and so will bathing with hot lye or alcohol. A large poultice of hops, soaked in hot vinegar, has also been found useful. TROUBLE WITH THE URINE.
