"'I doubt if my experience will be of much service, but it is the candid truth, from a woman who, in the cause of all the young girls who may be contaminated, desires to show just to what extent a young mind may be defiled by the injurious effects of round dances. I have not hesitated to lay bare what are a young girl's most secret thoughts, in the hope that people will stop and consider, at least, before handing their lilies of purity over to the arms of any one who may choose to blow the frosty breath of dishonor on their petals.'" Much more might be added on this important subject, would the limits of this work allow; but this must suffice. We beg the reader to consider carefully and prayerfully the facts presented before deciding that dancing is so harmless as many persons suppose. Physical Causes of Unchastity.--Some of the physical causes of impurity in women have been previously referred to, since it is through physical injuries that unhealthful clothing exerts its influence. Too little is generally known of the intimate connection between physical and mental conditions. Doubtless, many vices originate in physical imperfections. Indeed, when the full bearing of physical influences upon the mind is allowed, it is difficult to avoid pleading extenuating circumstances in the cases of the greatest share of transgressors of both moral and civil laws. This principle is especially applicable to sexual relations. In males, one of the most general physical causes of sexual excitement is _constipation_. The vesicula seminalis, in which the seminal fluid is stored, is situated, as will be remembered, at the base of the bladder. It thus has the bladder in front, and the rectum behind. In constipation, the rectum becomes distended with feces, effete matter which should have been promptly evacuated instead of being allowed to accumulate. This hardened mass presses upon the parts most intimately concerned in the sexual act, causing excessive local excitement. When this condition is chronic, as in habitual constipation, the unnatural excitement often leads to most serious results. One of these is the production of a horrible disease, _satyriasis_, the nature of which has been previously indicated. _Constipation_ in females has the same tendency, though the dangers are not quite so great. The irritation is sufficient, however, to lead to excitement of the passions. _Intestinal worms_ often produce the same result in children. _Local uncleanliness_ is another very frequent cause which is often overlooked. The natural local secretions quickly become a source of great irritation if not removed by daily washing. Certain anatomical peculiarities sometimes exist in the male which greatly aggravate this difficulty, and for which circumcision, or an equivalent operation, is the remedy.
