This multiplicity of virtual origins of the proper nerve is less conspicuous vs^liere the rhinencephalon is near the rest of tlie brain; but a careful analysis of the long olfactory nerve in the Eel, fig. 176, will show that it is a fasciculus of filaments distinct from their origin. The optic nerves, like the eyes, are of large relative size in most fishes; but where the organs of sight are small, the nerves are slender, as in the Silurus: they arc still more slender in the Myxinoids, and they are scarcely discernible filaments in the 197 *, ' - 198'.
