I say with regard to this, that pain is produced in the liver from a hot imposthume or by reason of oppilation or of flatulence. There671 is fever with the pain that comes from an imposthume, and little pain is caused by oppilation, as there is more heaviness therein than pain. As to672 the pain that comes from gross flatulence without fever, if fever supervene, without a doubt it cures it. Now as to the reason. I say there is no pain in the liver in tympanites, but only in the stomach, and in the guts, and the fever does not benefit the flatulence673 in the stomach.
