With regard to the position and mode of attachment of the latter, there is a fundamental difference between Pacini and M. Schultze (31), as appears from the two figures (241, a, b). While Pacini holds that the plates depend freely in the compartment, and are attached only at the lon- gitudinal septa, Schultze maintains that each transverse partition wall (Q) coheres with the posterior surface of the corresponding plate, so that there is a space only in front of, and not behind it. Both anterior and posterior surfaces of the plate are thickly set with papilla; (" villi," M. Schultze), behind which there are posteriorly, thorn-like processes (prolungamenti spiniformi, Pacini), which extend to the posterior partition wall, and are attached there. Schultze failed to discover the latter, while Sachs confirmed the observations of Pacini, as also for the cleavage of the plates (as observed by the latter), into an anterior and a posterior half. He regarded the papilla with their so-called " nuclei" (known later.
