IN the course of an investigation into the inheritance of coloboma of the optic nerve sheath in mice, I noticed that the lamina cribrosa is very poorly developed even in normal animals of this species. The lamina cribrosa, as is well known, is a net-work of collagen, elastic, and neuroglial fibres, partly continuous with the sclera through which the optic nerve fibres run on their way through the back of the eyeball (Salzmann, 1912). This network strengthens the eyeball at what would otherwise be a very weak spot. In the mouse a suggestion of a network is sometimes present (Fig. 1), but the fibres are extremely fine and often hard to see in sections; they do not take up collagen stains. An attempt was made to discover the nature of these fibres by the use of specific tissue stains. Staining with the azan and periodic Schiff aimethods, which give excellent reSUl s in other animals, failed to show any but the most rudimen7 ~~~~tary collagen development in any ~~ 44~ ji ~ ' mouse nerve; usutally the result /)~~ , was entirely negative.
