The dorsal roots of the nerves distributed to the free, explora-tory, pectoral rays of the Gurnards, rise from special ganglionicswellings of the cervical portion of the dorsal myelonal columns. § 56. Nerves of Reptiles.— The olfactory nerves are continuedin Reptiles, for a greater or less extent, from the rhinencephalon,figs. 188, 191, to the olfactory sacs; the white and grey tractsbeneath the prosencephalon, fig. 190, P, described as roots of thisnerve, belong to the rhinencephalic crura: the true olfactorynerves are less distinct from their centres than in other Ver-tebrates. In the Python, fig. 188, the nerves, \s of equaldiameter with their centres, gradually expand, by resolution oftheir fibres, as they approach the olfactory sacs,
