Laplace treated the subject from the point of view of the gradual aggregation and cooling of a mass of matter, and demonstrated that the form which such a mass would ultimately assume must be an ellipsoid of revolution whose equator was determined by the primitive plane of maximum areas.
The Uzbegs were no one race, but an aggregation of fragments from Turks, Mongols and all the great tribes constituting the hosts of Jenghiz and Batu.
