Experiential knowledge regarding an a’at growth on the lower part of his abdomen: When you identify this on the lower part of his abdomen, while the water of his abdomen rises up and descends, then you say for this: “(This is) an ailment **for which there is air* in/on the lower part of his abdomen. (This is) a disease that I will treat.” It is heat on the bladder that causes it. Subsequently, you remove* it (i.e. the growth) with a cauter. It (i.e. the cauter) should not go down as far as his mesinet body part. You should treat it according to the treatment by a cauterisation assitant.
