They who constitute the province of the kidneys, ureters, and bladder in the Grand Man, are of such a disposition that they desire nothing more than to explore and to search out the quality of others; and there are some of them who are eager to chastise and to punish, provided there is some justice in the case. The functions of the kidneys, ureters, and bladder are of this kind; for they explore the blood thrown into them to see whether there is any useless and hurtful serum in it, which they separate from what is useful, and then correct it; for they drive it down toward lower positions, and on the way and afterward they agitate it in various ways. These are the functions of those who constitute the province of the parts in question.
