Fig. 2. Section stained with bleu de Lyon. Sagittal, but not quite true. The section passes at a nearer the axial line than at b, hence passes at a through the cells from which fibres go to the chorda, and at b through the openings in the chorda sheath. In sectioning, the spinal cord has been torn from the chorda sheath to which however the fibres () are still attached. Ch. chorda. chorda sheath, longi- tudinal fibres in spinal cord. n. c. cells in central nervous system, op. openings in chorda sheath, pg. pigmented cells near the floor of neural canal, sp. space through which the spinal cord has been torn away from the chorda, fibres passing to the chorda sheath. from sagittal sections, it is evident that the fibres which enter the chorda sheath are prolongations of cells lying in tfie central nervous system. It is well known that the motor nerve fibres of Amphioxus leave the central nervous system separately, and not in large bundles in.
