Examined the olfactory reactions of amphibians. Spotted newt were used as Ss. An experiment was devised to test reactions to a stationary object; and to see if meat would be found more quickly than something which did not emanate any chemical stimulation. Results show that the approach to an object, edible or inedible, was a visual reaction, and that if smell played a part in food recognition, it did so after the animal has discovered and moved to the source of the stimulus. Hunger and movement of objects were important factors contributing to the reactions of the Ss. The olfactory receptors and not the gustatory ones were stimulated by substances in dilute solutions. Diemyctylus reacted to olfactory stimuli, and the sense of smell played an important role in food recognition. A. M. Reese's experiment on the same problem has been described.
