Sec. 357. There are many Women whose Customs visit them without the slightest Impeachment of their Health: others are sensibly disordered on every Return of them; and to others again they are very tormenting, by the violent Cholics, of a longer or a shorter Duration, which precede or accompany them. I have known some of these violent Attacks last but some Minutes, and others which continued a few Hours. Nay some indeed have persisted for many Days, attended with Vomiting, Fainting, with Convulsions from excessive Pain, with Vomiting of Blood, Bleedings from the Nose, _&c._ which, in short, have brought them to the very Jaws of Death. So very dangerous a Situation requires the closest Attention; though, as it results from several and frequently very opposite Causes, it is impossible within the present Plan, to direct the Treatment that may be proper for each Individual. Some Women have the Unhappiness to be subject to these Symptoms every Month, from the first Appearance, to the final Termination, of these Discharges; except proper Remedies and Regimen, and sometimes a happy Child-birth, remove them. Others complain but now and then, every second, third, or fourth Month; and there are some again, who having suffered very severely during the first Months, or Years, after their first Eruptions, suffer no more afterwards. A fourth Number, after having had their Customs for a long Time, without the least Complaint, find themselves afflicted with cruel Pains, at every Return of them; if by Imprudence, or some inevitable Fatality, they have incurred any Cause, that has suppressed, diminished, or delayed them. This Consideration ought to suggest a proper Caution even to such, as generally undergo these Discharges, without Pain or Complaint: since all may be assured, that though they suffer no sensible Disorder at that Time, they are nevertheless more delicate, more impressible by extraneous Substances, more easily affected by the Passions of the Mind, and have also weaker Stomachs at these particular Periods. Sec. 358. These Discharges may also be sometimes too profuse in Quantity, in which Case the Patients become obnoxious to very grievous Maladies; into the Discussion of which however I shall not enter here, as they are much less frequent than those, arising from a Suppression of them. Besides which, in such Cases, Recourse may be had to the Directions I shall give hereafter, when I treat of that Loss of Blood, which may be expedient, during the Course of Gravidation or Pregnancy. See Sec. 365. Sec. 359. Finally, even when they are the most regular, after their Continuance for a pretty certain Number of Years (rarely exceeding thirty-five) they go off of their own Accord, and necessarily, between the Age of forty-five and fifty; sometimes even sooner, but seldom continuing longer: and this _Crisis_ of their ceasing is generally a very troublesome, and often a very dangerous, one for the Sex.
