Abstract
FROM a knowledge of the mass of the Earth and its moment of inertia and from an analysis of seismic data, Bullen1 has reconstructed a pressure-density curve for the Earth's interior. The outer core of the Earth is believed to be liquid since it does not transmit transverse seismic waves while the structure of the inner core is still in doubt. The entire core is believed to be predominantly iron.
