Excerpt from Journal of Morphology, 1891, Vol. 4 Edinger's discovery of the cortical gray as distinct from the ventricular gray in the Reptilia (1, p. II 1) leads naturally to the supposition that the rudimentary cortex, if nothing more, must be present in the amphibian cerebrum, in which the mantel is, in its relative size at least, not so very different from that of the reptiles.1 And if we are able to find the homologous structure in Amphibia, what is the extent of that homology when we take into comparison the air ...

Excerpt from Journal of Morphology, 1891, Vol. 4 Edinger's discovery of the cortical gray as distinct from the ventricular gray in the Reptilia (1, p. II 1) leads naturally to the supposition that the rudimentary cortex, if nothing more, must be present in the amphibian cerebrum, in which the mantel is, in its relative size at least, not so very different from that of the reptiles.1 And if we are able to find the homologous structure in Amphibia, what is the extent of that homology when we take into comparison the air-breathing vertebrates as a whole? The first part of this paper contains the result of my observations along that line. The second part consists of investigations directed to determining the homology, and in part the functions, of the several layers described by Osborn and others in the tectum Opticum of Rana (2, p. 82) in comparison with those of the reptiles and birds.
