The part of the cornea immediately beneath the anterior epithehum, for a thickness of from to of an inch, is denser than the rest of the tissne, and entirely free from corpuscles (fig. 329, 2). It wasnamed the anterior elastic lamina by Bowman, but appears not to differmaterially in structure fiom the rest of the corneal substance, fibres ftomwhich may be seen passing obliquely towards, and becoming lost in it(fig. 329, a).
