A study of reaction speed, at different temperatures, of fresh-water snails (Helisoma trivolvis) is reported. Organic response to mechanical stimuli shows a definite relationship of reaction speed to the environmental temperature. There is an increase in rate of reaction from 40°F to 98°F; and a subsequent leveling off trend from 98°F to 110°F. Snail size has no appreciable effect upon reaction speed. Learning by experience is suggested.
