68. When the dejections are allowed to stand and not shaken, and a sediment is formed like scrapings (of the bowels), in such a case it is proper to purge the bowels; and if you give ptisans before purging, the more you give the more harm you will do. 69. Crude dejections are the product of black bile; if abundant, of more copious, and if deficient, of less copious collections of it. 70. The sputa in fevers, not of an intermittent type, which are livid, streaked with blood, and fetid, are all bad, it is favorable when this evacuation, like the urinary and alvine, passes freely; and whenever any discharge is suppressed and not purged off it is bad. 71. When you wish to purge the body, you must bring it into a state favorable to evacuations; and if you wish to dispose it to evacuations upward, you must bind the belly; and if you wish to dispose it to evacuations downward, you must moisten the belly. 72. Sleep and watchfulness, both of them, when immoderate, constitute disease. 73. In fevers which do not intermit, if the external parts be cold, and the internal burning hot, and fever prevail, it is a mortal sign. 74. In a fever which does not intermit, if a lip, the nose, or an eye be distorted, if the patient lose his sense of sight or of hearing, while now in a weak state,-whatever of these symptoms occurs it is mortal. 75. Upon leucophlegmatia dropsy supervenes. 76. Upon diarrhoea dysentery.
