either case much irritation and fever are produced by their presence in the passages, and serious symptoms would soon result if they were allowed to continue there. Hence we make it a rule, that whenever the patient requires to evacuate the bladder, she should do it by kneeling: by this means the position of the vagina is altered, and the accumulated discharges and coagula readily drain away and produce the greatest relief. Wherever the patient complains of abdominal pain, and the lochia has become scanty and somewhat offensive, it will be advisable to wash out the vagina with a warm water injection: for the farther treatment of these symptoms, we must refer the reader to the chapter on PUERPERAL FEVER. _After-pains._ When coagula have remained or formed in the uterus after labour, these irritate it by their presence, and excite it to contract: pains therefore of a crampy spasmodic character are produced, which have received the name of _after-pains_. Women who have already borne children are more liable to them than primiparæ. They vary considerably in degree: in some cases they are scarcely sufficient to excite attention; in others they rise to great intensity, and may even be mistaken for inflammation; indeed, they occasionally pass into this condition. During these pains the uterus is evidently in a state of contraction, for the fundus feels hard, and for the moment it is more or less painful to the touch: the patient has also pain in the back like a labour pain. After-pains do not only arise from coagula in the cavity of the uterus irritating it to contraction, but also from little plugs of coagulated blood, which fill the sinuses opening upon the internal surface of the uterus. After awhile they excite contractions, by which they are squeezed out and come away in the discharges: this fact was first pointed out by Dr. Burton in 1751. Having to introduce his hand into the uterus for the purpose of removing a portion of the placenta, he felt several of these little oblong fibrinous masses exuding from the orifices of the uterine sinuses, whenever he at all stretched the uterus by opening his hand; these proved to be so many fibrinous casts of the above vessels, the blood having been retained and coagulated in them, when the uterus contracted after the birth of the child. When the uterus has been slowly emptied during labour, it contracts gradually and uniformly, and forces the blood from its numerous sinuses into the rest of the circulation; but where its contents have been suddenly removed, the contraction is unequal, and a portion of the blood is retained, which coagulates as described. This fact affords an additional argument in favour of putting the child early to the breast: the active contraction of the uterus, which is thereby induced, effectually expels the coagula from its sinuses: hence we see that where a patient suckles shortly after labour, she seldom (_cæteris paribus_) has
