Cælius, the Methodist, treats so fully of the _cardiac passion_, that we feel at a loss how to give a competent outline of it within our limits. The followers of Asclepiades, he says, held it to be a swelling about the heart, connected with congestion; but, according to Soranus, the great master of the Methodists, the heart is not primarily affected; and he holds it to be an acute and sudden prostration, by which the distribution of particles over the passages of the body is stopped. The causes of it are many; such as protracted indigestion, intoxication, baths after food, vomiting after supper, and depressing passions, by which the body is dissolved into sweats. It takes place most frequently, he says, in continual, ardent, and inflammatory fevers on the sixth day. His description is too lengthy to find a place here. Suffice it to say that when the affection is at its height, the pulse is small, tremulous, and creeping; there is a profuse, viscid, and fœtid sweat over the chest, face, and perhaps the whole body, with failing respiration, pallid countenance, hollow eyes, and so forth. Some of the preceding authorities, such as Asclepiades and Themison, held that it was generally, but not always attended with fever; and with them he pretty nearly agrees. As we have already hinted, he is not disposed to admit that it is a primary affection of the heart, but rather holds it to be a disorder of the general system. Having discussed, in two chapters, the diagnosis, first, between it and affection of the stomach, and then between it and critical sweats, he comes to the treatment. The patient is to be laid in a cool and well-ventilated apartment, to be covered over with light clothes, and to have his face, neck, and chest sponged with cold water and vinegar; and if the sweating continue, astringents and obstruents, such as alum and Samian earth, are to be added; or the body may be anointed with astringent oils; but, in particular, various applications of a fragrant and astringent nature are to be made to the chest. He recommends great caution in the administration of food and drink; directs that the mouth should be rinsed with something cooling; and, in process of time, that various articles of a restorative nature should be given for food, and at last, wine, about the choice of which he is very scrupulous, approving, in general terms, of such as is white, well clarified, and subaustere, and in particular of the Surrentine, the Falernian, the Chian, and the Lesbian. He cautions, however, not to give too much at a time. When there is great prostration of the vital powers, he approves of ligatures to the extremities, and the application of cupping instruments, with great heat to the præcordia. When all other means fail, the patient is to be supported by administering nourishing things in clysters. Such is his own mode of treatment. He afterwards animadverts freely upon the practice of the other sects.
