to strengthen your expectations. In like manner you ought to judge of the other evacuations; or, if none of these symptoms should appear, but if there be uneasiness occurring on one of the critical days after the 20th; or if, when the disease is at its acme, pains should seize certain joints, or near the ears, or in other parts; or if not pains, but local sweats should occur unceasingly in any part of the body, then indeed you may expect a crisis to take place by abscess, and in that part where the sweats, pains, or swelling occurred. * * * * * COMMENTARY. This is taken with very slight alterations from Galen (Therap. ad Glauc. i: see also, de Crisibus, iii, 2.) The critical evacuations enumerated by Galen are, those by vomiting, by the belly, by urine, by sweats, by hemorrhage from the nose, by hemorrhoids, by the menses in women, by abscesses of the parotid glands, and by determination to the knees, feet, or some other parts not vital. He says there are three ways in which a fever may terminate favorably, namely, by an evacuation, by an imperfect crisis without an evacuation, and by resolution, that is to say, when the febrile symptoms go off gradually. There are likewise three unfortunate terminations; for the patient may die suddenly with much agitation, or in consequence of a metastasis, or he may be slowly wasted by a marasmus. Averrhoes enumerates the same kinds of critical evacuation as Galen, and otherwise treats of them very judiciously. (Collig. iv, 39.) Avicenna gives a long account of all the circumstances attending the crisis, but he copies closely from Galen and Hippocrates. (iv, 2, 1.) Haly Abbas, in like manner, is sensible and correct, but borrows from the Greeks. (Theor. x, 10.) The account given by Rhases is excellent, but it differs little from our author’s. (Ad Mansor. x, 27.) In his ‘Continens,’ he gives a full exposition of the Galenic doctrines, with his own Commentaries. He states, that a crisis may take place in six ways: by hemorrhage at the nose, by an alvine evacuation, by vomiting, by a discharge of urine, by a sweat, or by an aposteme. (xxxi.) SECT. XI.—HOW TO DETERMINE WHETHER A PAST CRISIS BE FAVORABLE. If a proper evacuation takes place after the concoction, and the fever is resolved by the critical evacuation; if the patient is freed from all other symptoms; if his colour has improved in proportion to the evacuation; if his pulse has become more regular, and his strength better in rising out of bed; and, what is the most salutary symptom of all, if these are accompanied by repose of the constitution, this may be pronounced to be the best possible crisis. If any of these be wanting, the goodness of the crisis will diminish proportionally to the force of the diminution. * * * * * COMMENTARY. This requires no Commentary. See, however, more fully, Galen and Rhases (l. c.) SECT. XII.—ON THE PULSE, FROM THE WORKS OF GALEN.
