Observations on the nerve fibres of Aurellia aurita

Abstract

Summary The nerve fibres of Aurellia aurita were originally described by E. A. Shäfer from gold preparations. This work has been repeated with Holmes's method of silver staining on the slide. Results have been obtained substantially in agreement with those of Shäfer.

The same nerves can be seen in the living animal when a phase-contrast microscope or oblique illumination is used. By the use of these techniques, a study has been made of the plan of the nerve net over the subumbrellar surface of the bell.

This work is intended as an anatomical foundation for physiological studies to be described elsewhere.
