    7* AGE. The following table shows the age of the patient, irrespective of the anaesthetic employed, in its relation to the incidence of complications and of danger :— Table XVII. Age Period. No. of cases. Percentage incidence. Division A (uncomplicated). Division B (complicated). Total (A and B). Danger cases (B y and B 8). Of complications (B).

After io there is a sudden drop, and in the age period “ u to 15 ” the complication and danger rates are the lowest recorded. From this age there is a steady rise for each decennial period until the age of 50 in the complication rate, and until 80 in the danger rate. The following tables show the percentage of complicated cases (Division B), and of danger cases (B 7 and B 8), in the different age periods, under the first four anaesthetics. Note.—The age period in the four following tables do not quite correspond with those of Table XVII owing to slightly different methods employed. Table XVIII.—Anaesthetic I. Age period. No. of Cases.
