From this plexus fine varicose ner\'e fibres may be traced passing up between the epithelium cells of the Malpighian layer. beneath- this lies a thick stratum of polygonal-shaped cells known as prickle cells (of Schulze), which have small inter- cellular channels between them for the passage of lymph for the nutriment of the cells. The channels are bridged over at intervals by processes from the cells, and when the cells are isolated for examination under the microscope these processes.
