ON THE MODIFICATION OF TEMPERATURE CHARACTERISTICS [PDF]
Journal of General Physiology, 1926 In December and January the frequency of heart beat in Limax exhibits µ = 11,500 ± 250. The ingestion of a small volume of sugar solution results in temporary change of µ to 16,200 ± 320, which accords quantitatively with the value obtained from these slugs in spring.
