Metrical Venn diagrams.

A type of Venn diagram is described which enables the observed frequencies in a 2x2x2 contingency table to be compared with their expectations on the hypothesis of no associations.

The structure of the Polar Eskimo genealogy.

The structure of the genealogy of the Polar Eskimos from the Thule District of North Greenland is studied by a variety of computational and graphical means, some of them novel. It is shown that although the level of inbreeding in the population is low, the genealogy is intricately connected, as if conforming to the requirement that spouses are as unrelated as is possible in a small population.

Selection at a multiallelic locus: Feller's transformation.

An explanation of Feller's result enabling the contours of mean viability at a triallelic locus to be rendered circular is offered, and a proof given which does not involve the direct use of homogeneous coordinates. In a subsequent paper we propose to use the fact that the same transformation also maps the contours of equal average effect for each gene into circles to establish further results.
