and preserve their health, that _perhaps_, it might lead to immorality and vice. This is ever the pretext to arrest the progress of physiological discovery. Discoveries, then, so directly and intimately connected with the personal individual happiness of every man, woman, and child, are alone to see no progress; without being met at the threshold with the senseless and idle cry of “vice and immorality.” Thus then, the sufferings, the pains, the anguish, which have existed five hundred years ago, are to be irremediable and endured in despite of any discoveries _by which they can be prevented_. We must do nothing to alleviate, or better still, to prevent, the sufferings of the wife, daughter, or mother, because it was not done five hundred years ago! Monstrously absurd as is this reasoning, yet it is of this kind which the discoveries introduced before the public in this work will be met. But the subject is one which embraces our social joys and comforts, the endearments of home and the family fire-side, the health and well-being of wives, mothers, and daughters, and cannot be retarded by the cobwebs in its way, to stem its onward course. No female, either married, or about to be married—no wife about becoming a mother—no mother having a daughter—no father who desires to prolong the health, beauty, and vigor of his offspring—no husband who has his own happiness, or the happiness of the companion of his bosom at heart—no young man, even, having a regard to his future welfare, should be without this important little work. Here the wife, mother or daughter, can detect her own complaints, trace them to their causes, and apply the remedy. This is all important. For, how often does the young female (because of a supposed delicacy), suffer in health rather than impart her malady to another, and especially to a medical man; and thus, many diseases, which though trifling in their origin, and at first easily removed, become seated and confirmed in her constitution. How deplorable are the consequences arising either from neglect or ignorance in the treatment of females who are afflicted with a stoppage, irregularity, or entire suppression of the menses or monthly turns, from which spring a train of diseases, which it would, in this place, be useless to enumerate, but which make our wives and daughters sickly, and our offspring short-lived. It is also important that the female should understand the cause which might occasion a stoppage of the menses to possess the information contained in this work, by which it can be ascertained whether it may not arise from pregnancy and thereby avoid that anxiety of mind arising from an uncertainty as to her real situation, alternately imagining the one or the other, as her inclinations or fears may tend.
