本文报道了几种C.在长达2年的时间内，分别每天、每周和每周记录外侧肌。在32° F、70° F和95-100° F的环境温度和恒定光照条件下，所有动物的体重均显示出约1年的周期性变化，这大致相当于食物消耗量。在这些恒定的光照和温度条件下，处于32° F和70° F的动物冬眠，即，它们的体温几乎下降到环境温度，变得迟钝。保持在95-100° F的动物体温不会下降，这些动物也不会变得迟钝。除去食物不能诱导冬眠，但如果在整个冬眠期结束时笼子里没有食物，冬眠时间会大大延长。冬眠的开始只能通过改变白天的长度而轻微改变。冬眠是可能的，只有在一个特定阶段的重量循环。
The state of torpidity (hibernation), the food consumption, and the weight of a number of C. lateralis were recorded daily, weekly, and weekly, respectively, for periods up to 2 years. At ambient temperatures of 32° F, 70° F, and 95–100° F and under constant lighting conditions, all animals displayed an approximately 1-year cyclic variation in weight which roughly paralleled the consumption of food. Under these constant conditions of light and temperature the animals subjected to 32° F and 70° F hibernated, i.e., their body temperature dropped nearly to the ambient and they became torpid. The body temperature of animals kept at 95–100° F could not drop and these animals did not become torpid.Hibernation could not be induced by removal of food but was greatly prolonged if food was not present in the cages at the time the whole hibernation period was ending. The onset of hibernation could be changed only slightly by changing the day lengths. Hibernation was possible only at a specific stage of the weight cy...
