8 It follows now that I have to explain the special signs which in any particular affection indicate either hope or danger.
8
When there is pain in the bladder, if purulent urine is discharged which has in it a sediment slimy and white, it allays apprehension.
8
In pulmonary disease a patient may possibly regain health, if expectoration, although purulent, relieves pain, so long as he breathes and expectorates freely, and bears the disease without difficulty. Nor is there cause for alarm at an early stage, if the expectoration is mixed with something reddish and with blood, so long as it is expectorated at once.
8
Pain in the side ends if the suppuration which has arisen is cleared off within forty days.
8
If there is an abscess in the liver, and the pus let out is uniform and white, in that case recovery is easy, because the mischief is enclosed in a capsule.
8
Among suppurations too those are tolerable which point and discharge outwards. And of those which move inwards, those are the most favourable which do not affect the overlying skin, but leave it free from pain, and of the same colour as the surroundings. Pus indeed causes no fear, wherever it breaks out, when slimy and uniformly white, and if the fever subsides at once upon its discharge, and distaste for food and thirst cease to be troublesome. Also whenever suppuration descends into the legs, and the patient's expectoration from being reddish becomes purulent, there is less danger.
