The causes of these fevers are oppilation and repletion, much resting as well as many other signs4; the consumption of food that increases sanguine humour, such as eggs, salmon5, and the like; avoiding accustomed work and purging, and practising laborious exercise along with repletion of the body;

the mutilation (want) of a member whitherto much blood was wont to flow; much foods6 that generate watery blood, and fruit, milk and fish, for such easily turn to purely watery humours7 and contract putrefaction, cause oppilation and greater heat, and give rise to the fever called synocha8. And should the leech be careless in opening the obstruction or evacuating it, it readily turns to the fever called synochus. Therefore Haly9 says the excess does harm in three ways: as regards quality only, as the blood when it heats and generates the fever called ephemera; or he takes the blood there for the spirit, which is generated from the thinnest part thereof {Vel capit sanguinem pro spiritu, qui ex parte purioris sanguinis generatur.}’’R. A. 811.
Or the excess is generated as regards quantity alone, when the blood increases in quantity only, its quality only being good, and not a corrupt quality10, it then causes the fever called synocha. And the pus in the imposthume injures by reason of quality and quantity [combined].
