The Earth's Density [Book Review]

Bullen's name is associated with many of the early developments in seismology including the Jeffreys-Bullen travel-time tables and the Bullen density models. His interest in the methodology of scientific inference has always been evident in his papers and continues in this monograph. The Earth's Density is a superb account of the history of a science, starting from ancient determinations of the size and the mass of the Earth up to the modern age of computer inversion.
