摘要：The moments of the functions m P/m 2 P12 are derived, where m p is the pth moment of samples from a normal universe. Relationships between two-dimensional semi-invariants of the type S kl(m 2, m p) when l is constant and k varies, are also demonstrated.

摘要：Measurements and type contours of skulls of the Naga tribes of Eastern Bengal, Assam and north-west Burma are given. The Naga skulls are most closely related to the Tagals of the Philippine Islands, the Dayaks of Borneo, southwestern Tibetans, and Nepalese.

摘要：The P[lambda]n test appeals first to the principle of independent probabilities, to ascertain the probability of more improbable individual occurrences, and then starting from this probability measures the probability of all sets of occurrences, not necessarily greater in each individual variate but more improbable as a whole set. It seems to involve fewer approximations and assumptions than the [chi]2 test, especially for small samples. Because a set of occurrences is found on hypothesis H1 n...

摘要：By the cranial coordinatograph the Cartesian coordinates of any point on the skull are obtained. Since skulls are somewhat asymmetrical the median sagittal plane as customarily determined from 3 points is unsatisfactory. The plane of minimum square deviation from 13 mid-sagittal points is therefore proposed as a more satisfactory sagittal standard plane. The 3 standard planes are mutually perpendicular. The horizontal plane makes a minimum angle with the Frankfurt horizontal plane, while the p...
