Nervous system; Jellyfishes; Starfishes; Sea urchins; Nerveux, Système; Méduses; Astérides; Echinides. Fig. 18. In such experiments, the recovery of the nonnal rate in impoisoned water is gradual. Taking, for instance, the case of a spiral strip in morphia (Fig. 19), it will be seen that the original rate did not fully return. Some substances, however, exert a more marked permanent effect of this kind than do weak solutions of morphia. Here, for instance, is an experiment with alcohol (see Fig.
