VII.—On Some Points in the Early Development of Motor Nerve Trunks and Myotomes in Lepidosiren paradoxa (Fitz.)

Abstract

My main purpose in the following short paper is to publish figures illustrating some of the more important facts of the early development of myotomes and motor nerves inLepidosiren. The bearing of some of the observations of nerve development upon current theories renders it particularly desirable that they should be illustrated by untouched photographs of the sections. A few photographs illustrating the more important stages in the development of the motor nerve trunks are given on Plate I. For the preparation of the photographs here published, as well as several others, I am indebted to the skill of my friend Dr T. H. Bryce, and of Mr Fingland, our University photographer.
