These methods, as pointed out by Guild,1 Jones2 and Anson, Wilson and Gaardsmoe,3 are not always accurate and should be supplemented with a study of serial histologic sections. The demand for observations on pneumatization of the petrous bone based on serial histologic sections warrants this report.

REVIEW OF THE LITERATURE  In the study of air cells various methods have been employed. Bezold4 and Siebenmann5 employed the corrosion method.Another method was to make dissections of saw cut sections of petrous bones. Using this gross method, Belinoff and Balan6 studied petrous bones and
