This cannot be explained, but must be referred to the laws of pe- riodicity, which are entirely unknown. II.

In this case, as se- cretion from the capillary arteries {Flet. ii. 26) is, cceteris paribus, great in proportion to the quantity of blood they contain, these vessels, as they slowly recover their irritability, act upon the greater quan- tity of blood contained in them, and give rise to increased deposition of solid or fluid matters.
