Sometimes, however, the network is so close, or the meshes filled up with material so identical in refractive power with the bars or films of the network, that the whole substance appears ; The only means we have of getting any further knowledge of this arrangement is by staining it with various dyes, and observing the effects of the dyes upon the various parts.
