When the bladder is wounded, the groin is pained, there is a tension of the parts immediately above the pubes; instead of urine comes blood; and the urine is discharged at the wound; the stomach is affected, so that the patients either vomit bile, or have a hiccough; a coldness seizes them, and after that death. [Sidenote: _Of the discharge from wounds and ulcers._] [Sidenote: _Blood, sanies, and pus._] [Sidenote: _Ichor._] [Sidenote: _Melicera._] [Sidenote: _Elæodes._] These things being known, there still remain some other particulars to be observed relating to the wounds and ulcers, which we are to treat of. From wounds then and ulcers are discharged blood, sanies, and pus. Blood is known to every one. Sanies is thinner than blood, unequally thick, glutinous, and coloured. Pus is very thick and white, also more glutinous than either blood or sanies. Now blood is discharged from a recent wound, or one that is just healing: sanies appears betwixt these times: pus in an ulcer beginning to heal. Further, both sanies and pus are distinguished into several species by Greek names; for there is one kind of sanies, which is called ichor[EO], another melicera[EP]. There is also a species of pus called elæodes[EQ]. Ichor is thin, of a whitish colour, and proceeds from a bad ulcer, and especially where a nerve has been hurt, and an inflammation has followed. Melicera is thicker, more glutinous, whitish, and somewhat resembling white honey: this also is discharged from malignant ulcers, where the nerves about the joints are hurt; and amongst the joints principally from the knees. Elæodes is thin, whitish, somewhat unctuous, in colour and fatness not unlike to white oil; and appears in large ulcers, that are healing. Now blood is bad that is either too thin or too thick, in colour either livid or black; or mixed with phlegm, or of various colours: the best is warm, red, moderately thick, and not glutinous. Therefore from the first the cure of a wound, which has yielded good blood, is more easy and quick: and afterwards there is more hope of those, from which the several discharges have been of the best kind. Sanies then is bad, where it is in great quantity, over thin, livid, or pale, or black, or glutinous, or fetid, or such as corrodes the ulcer itself and the adjacent skin. It is better, when the quantity is small, indifferently thick, of a reddish colour, or inclining to white. Ichor again is the worst, that is plentiful, thick, inclining to a livid or pale colour, glutinous, black, hot, fetid. It is more tolerable, if inclining to white, and when in all other respects it is the reverse of the former. But melicera is bad, when it is in great quantity, and very thick; better, when thinner, and less in quantity. Pus is the best amongst these. But even that too is bad, when it is copious, thin, diluted; and the more so, if it be such from the beginning; also if in colour it resemble serum, if it be pale, or livid, or feculent; moreover if
