Rodbard（1）在最近的一篇论文中提出，各种哺乳动物的平均正常体温与体重有简单的关系：在小于1 kg的动物中，温度与体重的对数成正比（T= C+1.5logW），在较大的动物中，温度与体重的对数成反比（T= C ′-1.5logW）。从文献中选择了30个物种的值来支持这一论点，这些数据确实显示出与假设关系的密切联系。然而，最近对小型哺乳动物体温的研究，以及对文献中数值的一般考虑，使我们相信这种关系是无效的，并且这种明显的相关性（1）是由于数据表示不充分造成的。此外，如果不是因为成年个体的平均体重出现了3 ~ 30倍的误差，那么，即使是其中的某些物种也不符合假设的关系。这里提供的数据仅限于两个主要来源，因为从文献中给出哺乳动物体温的完整列表是不可行的，而且这些进一步的值不会改变结论。这两篇文章是Wislocki的综述文章（2），主要涉及较大的哺乳动物（2-2000 kg），以及最近未发表的测量，涵盖了一些较小的哺乳动物（1-2000 g）。除了单孔目动物、有袋类动物、无齿动物和蝙蝠的数值外，还列出了从这两个来源获得的所有数据，在这些群体中，发现温度水平低和/或相当不稳定。
In a recent paper Rodbard (1) proposed that the mean normal body temperature of variousmammals bears a simple relation to the body weight: specifically, that the temperature is directly proportional to the logarithm of the body weight in animals smaller than 1 kg (T= C+ 1.5 log W), and inversely propor-tional in larger animals (T= C'-1.5 log W). Values for 30 species were selected from the literature to support this thesis, and these data as figured did indeed show close adherence to the postulated relation. However, recent studies on body temperatures in smaller mammals, together with a general consideration of values in the literature, have convinced us that this relation is not valid, and that the apparent correlation (1) resulted from an inadequate representation of data. Further, even certain of the species there presented would not fit the postulated relation were it not for what appear to be errors of three-to thirtyfold in the average adult weights. The data presented here are limited to two major sources, since it is not feasible to give a complete listing of mammalian temperatures from the litera-ture and since such further values do not alter the conclusions. The twosources are Wislocki's review article (2), which principally relates to the larger mammals (2-2000 kg), and recent unpublished meas-urements' which cover a number of the smaller mam-mals (1-2000 g). All data available from these two sources are presented, with the exception of values on monotremes, marsupials, edentates, and bats, groups in which a low level and/or a considerable lability of temperature is found.
