From branches arching moreor less irregularly along this border ascend vertical branches. STRUCTURE OF THE KIDNEY. 33 These pass into the labyrinth midway between two medullaryrays, and are called interlobular or interfascicular them pass off, laterally, numerous smaller branches calledafferent,—vasa afferentia,—each one of which promptly perfo-rates the nearest Malpighian capsule at a point opposite to theconstricted neck of the latter. The vas afferens, according to themeasurements of Thoma,* is .014 to .02 mm. (y^gg to ^^^jinch) in diameter. Having perforated the capsule, it immedi-ately splits up, forming a capillary ball—the Malpighkin tuft orgloriienile. The capillary vessels of this ball reunite within the.

The resulting network em-braces partly the straight tubules of the medullary ray, andpartly the tortuous tubules, and, in the extreme peri
