Sterility depends either on imperfect organization, or imperfect action of the organs of generation. In the former cases, which are rare, the menses do not generally appear, the breasts are not developed, and the sexual desire is inconsiderable. There is no remedy in these cases. The action may be imperfect in several respects. The menses may be obstructed or sparing, or they may be too profuse or frequent. It is extremely rare for a woman to conceive who does not menstruate regularly. Hence where this is the case the first step is to regulate this periodical discharge. For this purpose the advice of a physician will generally be required, for these irregularities depend upon such various causes and require such a variety of treatment that it would be inconsistent with the plan of this work to give instructions for remedying them. A state of exhaustion or weakness of the uterine system, occasioned by too frequent intercourse, is a frequent cause of sterility. The sterility of prostitutes is attributed to this cause, but I doubt it being the only one. With females who are apparently healthy, the most frequent cause is a torpor, rather than weakness of the genital organs. For the removal of sterility from this cause, I shall give some instructions, and this I do the more readily because the requisite means are such as will regulate the menses in many cases, where they do not appear so early in life, so freely or so frequently as they ought. In the first place, it will generally be necessary to do something toward invigorating the system by exercise in the open air, by nourishing food of easy digestion, by sufficient dress, particularly flannel, and especially by strict temperance in all things. With this view, also, some scales which fall from the blacksmith's anvil, or some steel filings may be put into old cider or wine (cider the best), and after standing a week or so, as much may be taken two or three times a day as can be borne without disturbing the stomach. All the while the bowels are to be kept rather open by taking from one to three of _Pill rufi_ every night on going to bed. These pills consist of four parts of aloes, two parts of myrrh, and one of saffron, by weight.
