Variation in the frequency and severity of porotic hyperostosis [porous defects], seen in the skulls of individuals buried at two First Dynasty cemeteries at Abydos, suggested differences in health and social conditions. Those buried near the kings had suffered from childhood deficiencies, while those associated with funerary enclosures in a second cemetery further to the north seemed to have benefited from occupational or social advantages. The author speculates on the possible factors which gave rise to this difference.
