This appearance is occasioned by thepresence of a layer of very large oval cells (Figs. 183,184, b, b), which lie detachedone from anotherupon the surface ofthe ordinary cuticle,a a.—In other in-stances, the cuticleis partially investedby a layer of scales,which are nothingelse than flattenedcells, often having avery peculiar form;whilst in numerouscases, again, we flndthe surface besetwith hairs, whichoccasionally consistof single elongatedcells, but are more commonly made-up of a linear series,attached end-to-end, as in Eig. 153. Sometimes these hairsbear little glandular bodies at their extremities, by the secre-tion of which a peculiar viscidity is given to the surface of t
