Note 175 — Chapter VII · THE ELEMENTARY STRUCTURE OF THE NERVOUS SYSTEM.
Reading edition
Mayer, Op. cit., 393. I cannot, however, agree with Mayer when he says that the continuity of a nerve-fibre with a cell has never been distinctly shown (p. 395); in the Invertebrata and in the Electric fishes such a continuity is undeniable; and it has occasionally been seen in Vertebrata.
