On the contrary, when there is a pain in the head in a continued fever, and it does not at all remit, it is a bad and mortal symptom: and boys from the seventh to the fourteenth year are most liable to this danger. In a peripneumony, if the spitting did not come on in the beginning, but after the seventh day, and has continued above other seven days, it is dangerous: and the more mixed and less distinct the colours are, so much the worse. And yet nothing is worse, than for it to be excreted entirely homogeneous, whether it be reddish, or bloody, or white, or glutinous, or pale, or frothy: but the worst of all colours is black. A cough and catarrh are dangerous in the same disease; also a sneezing, which in other cases is reckoned salutary; and there is the greatest danger of all, if these things have been followed by a sudden purging. Now generally the symptoms, which are either good or bad in peripneumonies, are so in pleurisies too. A discharge of bloody pus from the liver is mortal. These are the worst kinds of suppurations, which tend inward, and discolour the external skin at the same time. Of that kind, that breaks outward(14), the worst are those, that are largest and flattest. But if the fever has not gone off, when the vomica is broke, or the pus evacuated, or after its ceasing returns again; also if there be a thirst, or a nausea, or a loose belly, or livid and pale pus, if the patient expectorates nothing but frothy phlegm; then there is certain danger. And of these kinds of suppurations, which have been produced by diseases of the lungs, old men commonly die: but those; those that are younger, by the other kinds. But in a consumption, a mixed and purulent spitting, a continued fever, which also destroys the appetite, and torments with thirst, in a slender body are sure prognosticks of immediate danger. If one has lasted under this distemper even for a considerable time, when the hairs first fall off, when the urine has something floating upon it like cobwebs, and the spittle has a fetid smell, and particularly when after these a purging has appeared, he will die soon: and more especially if it be autumn: in which season commonly those, that have got over the other part of the year, come to the close of their life. It is also mortal in this distemper to have expectorated pus, and afterwards for that to have entirely disappeared. It is likewise common for this disease in young people to arise from a vomica or fistula; and they do not readily recover, unless many salutary symptoms have ensued. With regard to others, virgins are the hardest to cure, or those women, that fall into a consumption from a suppression of the menses. A healthy person who has been taken with a sudden pain of his head, and then fallen into a deep sleep, so as to snore, and does not awake, will die before seven days are expired: and more especially if, when a looseness has not preceded, his eyelids are not closed in sleep, but the white of his eyes appears.
