    The externa] stratum, the epidermis, com- posed entirely of epithelial cells, lias be(Sn de- Bcribed as consisting of two layers —the exter- nal being termed the corneous and the internal the MaVpighian. The scarf-skin raised on the external surface of the skin by a blister, and the pellicle detached from the palate by hot drinks, represent the corneous layer of the epi- dermis ; by some authors this is called the true epidermis, and by some the cuticle.'1 This layer is composed of the old epithelial cells which have ceased to perform any of the vital functions. The subjacent layer, formed of living epithelial cells, which vary in form and size, is denominated (among- many other terms) the stratum Maljrighii. Underneath these two subdivisions of the epi- dermis of the mucous membrane (according to the nomenclature here adopted) we shall find the dermis {derm or derma). .But lest I should mislead you I will mention here that there is a transparent amorphous pellicle which separates the lower stratum of the epidermal cells from this latter layer. This structureless tissue is described by Todd and Bowman under the name of basement membrane, and by Eenle under that
