As a step toward clarifying the causes of brachycephalization, it was examined whether there was any association between the neurocranium and the humerus. Principal component analyses based on 30 male and 20 female skeletons show that cranial length is highly significantly associated with many measurements of the humerus, e.g., the circumference of the head, maximum length, minimum circumference of the shaft, minimum deltoid diameter, etc. On the other hand, cranial breadth is found to have no consistent association with any of the humeral measure-ments dealt with. These results support the previous suggestion by the present author that cranial length and cranial breadth tend to have some different kinds of connections with postcranial bones. As a cause for such different tendencies, it is inferred that the general development of skeletal muscles including nuchal ones and those of the upper limbs has more influence on the variation of cranial length than on that of cranial breadth.
