Unpublished paper, 'Development of the layers of the retina in the chick after the formation of the optic cup' by John Cameron
Reference number: AP/75/9
Date: 1902

Description
Cameron writes that the inner wall of the retinal cup in a 'fourth-day chick' has exactly the same structure as the wall of the embryonic cerebral vesicles or spinal cord at the same stage of development. Thus all the structures which His has described in the wall of the embryonic spinal cord can be also recognised in the inner wall of the retinal cup, and may therefore receive similar names. He describes a network (the myelospongium), which is produced by the union of the processes of cells called spongio-blasts. The outer and inner extremities of the myelospongium network fuse to form the external and internal limiting membranes respectively (the external limiting membrane of the retina corresponds to the internal limiting membrane of the embryonic spinal cord or cerebral vesicle as it is next to the cavity of the original optic vesicle).
Includes 20 magnified figures of embryos.
