Restlessness precedes every crisis, and if the crisis be to take place by day, it will occur by night; or if the crisis be to take place during the night, it will occur by day; and then certain symptoms supervene, such as headach not previously occurring, sympathetic pain of the neck, retraction of the hypochondrium, sudden difficulty of breathing, and other dangerous symptoms which did not manifest themselves before then take place. And if, when these occur, the pulse, instead of sinking, is increased in magnitude and becomes stronger, and the critical day approaches, and if it be one of the favorable, you may not only anticipate a crisis, but also a good one. And be not then alarmed if you see the patient become delirious and disturbed, for these are indications of the humours being carried upwards; in like manner as certain other symptoms indicate their being determined downwards, such as pain of the belly, gripes about the navel, pain in the loins, borborygmi, and other similar symptoms, when they occur. In addition to these, if the patient was accustomed to have a hemorrhoidal discharge, and if the period of it be at hand, and in like manner with respect to the menstrual discharge (if the patient be a woman), it is not unlikely that the crisis may take place by such an evacuation. And a critical sweat is recognized by a precursory moistness of the skin (especially if occurring upon one of the days called indicatory), and by openness of the pores. From these you may recognize crises by evacuations upwards; for, in addition to the aforesaid, you ought to examine the face of the patients, and whether there be palpitation in any part, or throbbing of the temporal arteries; or if the cheek, nose, or eye be redder than usual, you ought the rather to anticipate the coming crisis. But if they shed tears involuntarily, or fancy that they see sparks of light, and constantly carry their hands to their nose as if to rub it, then indeed you may see not only an approaching but a present flow of blood; for when they rub it once or twice the blood straightway breaks forth. Pungent pain at the stomach, and trembling of the under-lip often indicate a crisis by vomiting. These considerations are sufficient, but to them may be joined the age and constitution of the patient, as strengthening the anticipation; to which may be added, the season of the year and the present constitution. For if the patient be a child, or otherwise by nature warm and full of blood, you may still more form this anticipation; or if formerly, when in health or disease, as we remarked before, an evacuation of blood appeared, this circumstance alone may be sufficient to make you expect a hemorrhagy. And if the season of the year be summer, or, if not summer, if the present state of the weather be hot, and if the patient had often experienced a crisis at that season by hemorrhage, if the body be plethoric, if there is retention of the customary evacuations, all these things ought
