| Title | Paper, 'On the development of the cranial nerves of the newt' by Alice Johnson and Lilian Sheldon |
| Creator | Johnson; Alice (fl 1884-1885); Demonstrator of Biology, Newham College, Cambridge |
| Sheldon; Lilian (1862-1942); English zoologist |
| Date | 1886 |
| Description | Johnson and Sheldon write: 'The peripheral nervous system of the newt does not begin to develop until the medullary canal has become completely separate from the external epiblast. A neural ridge appears on the dorsal surface of the medullary canal, and, at regular intervals, paired lateral prolongations of it grow out and form the spinal and cranial nerves. The former grow down between the medullary canal and muscleplates, the original outgrowth, in each case, becoming the dorsal root, while the ventral root is formed later. In the head, where there are no muscle-plates, the nerves are situated nearer to the surface.'
