over, it ought to be shorter and more mild; so as only to soften the surface of the skin, to render it more apt to receive new matter from fresh nourishment. A patient is known to be in a bad situation, when the surface of his body is cold, and the internal part is hot with a concomitant thirst, as I observed above. But even in this case friction is the only remedy, which, if it have brought out the heat, may make way for the use of some medicine. CHAP. XV. OF GESTATION. Gestation is most proper for chronic distempers, and those that are already upon the decline. And it is useful both to those, who are quite free of a fever, but yet are not able to exercise themselves; and those, that have the slow relicks of distempers, which are not otherwise expelled. Asclepiades said, that gestation was to be used even in a recent and violent, and especially an ardent fever, in order to discuss it. But that is dangerous; and the violence of such a distemper is sustained better by remaining quiet. Yet if any person will make trial of it, he may do it under these circumstances, if his tongue is not rough, if there be no tumour, no hardness, no pain in his bowels, nor head, nor præcordia. And gestation ought never to be used at all in a body that is pained, whether in the whole, or in any part, unless the pain be in the nerves alone; and never in the increase of a fever, but upon its remission. There are many kinds of gestation: in the use of which the strength and circumstances of the patient are to be considered; that they may neither dissipate too much a weak man, nor be out of the reach of one of small fortune. The most mild kind of gestation is in a ship, either in a port, or a river; or in a litter, or a chair; more brisk in a chariot; more violent in a ship on the ocean. And each of them may be rendered both more sharp, and more mild. If none of them can be done, the bed must be suspended and moved to and fro. If even that can’t be accomplished, at least a prop is to be put under one foot(27) of the bed, and thus the bed moved back and forward by the hand. And indeed the mild kinds of exercise agree with the weakest; the stronger with those, who have been for several days free from the fever; or those, who feel the beginnings of severe distempers, but are yet without a fever (which is the case in a consumption, and indispositions of the stomach, and a dropsical disorder, and sometimes in a jaundice) or when some distempers, such as an epilepsy or madness, continue, though for a considerable time, without any concomitant fever. In which disorders, these kinds of exercises also are necessary, which were mentioned in that place, where we prescribed rules for the conduct of sound, but weakly men. CHAP. XVI. OF ABSTINENCE.
