In this paper, I shall give the results of the latter report3 first and then a new classification of the forms of epigastriograms.

STATISTICAL AND ORTHODIAGRAPHIC STUDIES  For the statistical research, the epigastric pulsation is classified into five types, A, B, C, D and E, as shown in the accompanying table.Examination of 2,000 healthy men. from 12 to 60 years old, showed that all types of pulsation in those under 20 years of age remain almost constant. Relative nonpulsation (D) occurred in 60 per cent;
