Note 212 — Chapter XIX
Reading edition
Dohrn believes that he has succeeded in shewing that the first pair of appendages of Limulus is innervated in the embryo from the supra-œsophageal ganglia. His observations do not appear to me conclusive, and arguing from what we know of the development of the Arachnida, the innervation of these appendages in the adult can be of no morphological importance.
