It is known that there is a whole series of secretions of the blood's liquid components occurring in the general region from the kidneys to the bladder, and that the ducts called renal pelves widen out. It is also known that these secretions of liquid components range in series from the smallest particles of that kind, to the medium ones, to the last ones-those in the ureter, where a cortical-like tissue passes into a striated one. Through these substances the medium liquid components are discharged.

Those relating to the medium liquid components are near the side, below the elbow, and speak with a rather harsh, cracked voice. They also try to make their way inside, but it is only an attempt, the act does not follow. They do nothing but think, reviewing the things in their experience that they have observed in other souls and spirits, whom they picture to themselves in recognizable mental images, thereby portraying them as if they were those very souls and spirits. In this way, by drawing out their thoughts and examining them, they investigate whether they share anything in common.
