Abstract

Following a survey of the problems associated with the comparative study of measures of physique in domesticated and laboratory animals, techniques were developed for the measurement of body build in the adult albino laboratory rat (Rattus norvegicus). They involved anesthetisation of the animals and the use of calipers and a simple apparatus devised for the purpose. The 17 measures taken on 100 rats, 50 of each sex, are detailed and the reasons for excluding other given. Intercorrelations of all the measures and their reliability co-efficients, which were judged satisfactory, are presented. The tables of intercorrelations, one for each sex, were factor analysed separately, and rotations to simple structure performed. Two factors were identified, one having factor saturations on measures of body length and the other similarily defining body width. This pattern was similar for the two sexes and a single index of body build was therefore proposed in which the length of the rear foot is divided by the width of the shoulder girdle and multiplied by 100 to avoid decimals. The use of the index in other investigations is mentioned.

大鼠体质因素分析。

在对与家养动物和实验动物体格测量比较研究相关的问题进行调查之后，开发了测量成年白化实验大鼠(褐家鼠)体格的技术。其中包括对动物进行麻醉，使用卡尺和为此目的设计的简单仪器。详细介绍了对100只大鼠(雌雄各50只)采取的17项措施，并给出了排除其他措施的理由。给出了各指标间的相互关系及其可靠度系数，并得出了满意的结果。相互关系表，每个性别一个，分别进行因素分析，并进行简单结构的旋转。确定了两个因素，一个具有测量体长的因素饱和度，另一个类似地定义了身体宽度。这种模式在两性中是相似的，因此提出了一个单一的体型指标，即后脚的长度除以肩带的宽度，再乘以100以避免小数。还提到了在其他调查中使用该指数的情况。

期刊介绍： The American Journal of Physical Anthropology (AJPA) is the official journal of the American Association of Physical Anthropologists. The Journal is published monthly in three quarterly volumes. In addition, two supplements appear on an annual basis, the Yearbook of Physical Anthropology, which publishes major review articles, and the Annual Meeting Issue, containing the Scientific Program of the Annual Meeting of the American Association of Physical Anthropologists and abstracts of posters and podium presentations. The Yearbook of Physical Anthropology has its own editor, appointed by the Association, and is handled independently of the AJPA. As measured by impact factor, the AJPA is among the top journals listed in the anthropology category by the Social Science Citation Index. The reputation of the AJPA as the leading publication in physical anthropology is built on its century-long record of publishing high quality scientific articles in a wide range of topics.
