Gross morphological total and agewise incidence of coronary sclerosis, graded as to severity and expressed as percentage of the corresponding age group. Data from over 3,000 consecutive male autopsies reported by Willius, Smith and Sprague (1933). The number of cases in each age group is indicated at top of the column. (Master, Friedman and Dack, 1942; Simonson and Keys, 1956). Although there may have been important differences in the manner and effectiveness of selection of these "normals", it would have to be admitted that they do not represent "pure" normals, but are carefully selected subjects in whom, statistically, coronary sclerosis is present with increasing agewise incidence and severity. To have obtained a lesser contaminating incidence of disease, one would need to have known at least the information which was supposed to result.
