Title | Paper, 'On the presence and structure of Leydig's "frontal organ" in Lacertilia' by W [Walter] Baldwin Spencer |
Date | 1886 |
Description | Baldwin writes: 'In 1872 Leydig described a structure in Lacerta agilis, L. muralis, L. vivipara,and Anguis fragilis, to which he gave the name of “frontal organ.” In the embryo, owing to its being deeply pigmented, it forms a prominent feature on the roof of the original forebrain in connexion with the pineal gland; in the adult it lies immediately beneath the skin, and, according to him and subsequent observers, completely separated from the brain.'
