Textbook of normal histology: including an account of the development of the tissues and of the organs . ars as a seemingly ho-mogeneous glassy layer, about 20ftin thickness in the middle of the cor-nea, gradually diminishing towards theperiphery. The resolution of thislamina into delicate connective-tissue fibrillae after treatment withsuitable reagents demonstrates itstrue nature as a specialized portion ofthe substantia propria. The fibrous stroma, or the sub-stantia propria, constitutes the chiefbulk of the cornea, and is made upof parallel lamellae composed of in-terlacing bundles of fibrous connective tissue. The exact num-ber of corneal lamellae is inconstant, since this depends upon theextent to which the artificial separation of the tissue is carried. Theinterlacing bundles of the white fibrous tissue composing thelamellae are united by the interfibrillar cement substance, and crossone another obliquely at various angles, the adjacent bundles beingintimately united by bands, the fibrae arcuatae, which pass fromone bundle to the other ; the arcuate fibres are especially prominent.
