When a cramp is violent, and there is any stop-page of the usual evacuation of blood, the patient must bleed, as also when the patient is full of blood, and the evacuations if possible must be restored. If this method fails, recourse must be had to the same remedies as in the falling sickness. Outwardly, rub the part with Hungary water, or the saponaceous liniment, commonly called opodeldoc; as also with the green oil alone, or mixt with essential oil of rosemary. Likewise, the back bone, from the neck downwards, may be rub'd with the same things. When the part continues hard, anoint it with ointment of marsh-mallows, or neats soot oil, or the green ointment, or the oil of amber. If these fail, recourse must be had to the temperate baths, the drinking mineral waters, using regular diet, and keeping the mind easy.
Crisis Various are the opinions of authors, about the nature and certainty of a crisis; but leaving them to their own judgments, I shall only relate what is agreeable to observation and experience. The crisis has been defined by some to be a sudden change in a disease, either for life or death. These changes happen on certain days, which are called critical days: they are reckoned by septenaries, and femiseptenaries, that is, every seven days, and half seven days or three days and a half. This crisis is performed by excretions; that is, by sweat, stool, or an haemorraage. On all other days, they are only sympto-matical.
The fever called an ephemera, comes to a crisis in twenty-four hours, and then ceases. A continual fever without re-million, the fourth day or seventh, by a bleeding at the nose with sleepiness, or a large sweat. Burning and bilious fevers, on the fourth or eleventh day, by a profuse sweat, often by a flux of the belly. A continual tertian remits on the third or fourth day, and turns to an intermittent. Catarrhal and epidemic fevers have been observed to remit on the third or fourth day, with pustules about the nose and lips, and an itching sweat. A flight pleurisy has gone off between the third and fourth day, with the expectoration of bloody matter with a cough; in very young persons on the seventh; in those that are older, and the dife?.fe more violent, on the fourteenth, with a large sweat, copious spitting, and a free respiration. A bastard pleurisy generally ends on the seventh or eleventh day, by a sweat or looseness.
An eryipclaceous fever abates between the third and fourth day, when an acrid bilious matter is sent to the skin. The plague throws out buboes and carbuncles on tie third, fourth, or seventh day. The small pox and measles generally appear between the third and fourth day. In the spotted fever, the spots appear on the fourth or seventh day. There is a kind of crisis in intermitting fevers, by scabby eruptions about the lips; and many chronic diseases go off by eruptions on the skin, ulcerous pustules, and the like. Likewise sleepy diseases, the vertigo and convulsive asthma, have been turned into the gout.
