✦ Synopsis

A simple method for graphically recording on the kymograph the neuromuscular activity and general behavior of small fish has been described.

This method has been employed by the authors for pharmacological study of the comparative effects of various drugs on goldfish.

A striking difference was noted in the ichthyograms produced by goldfish placed, respectively, in solutions of certain organic mercurials and of inorganic mercury salts, the former being much less toxic than the latter.

The ichthyometric method has proved useful not only in differentiating between organic and inorganic mercury compounds but also in discovering the presence of inorganic mercury contaminants in mercurochrome.
