HEART CASES IN THE RACE Of the 5 runners who had murmurs before the race, 4 ran the full distance and one ran nineteen miles. Three of these were among the first 12 to finish the race. ‘These runners were all new to long-distance running. After the race the hearts were auscultated in the first 45 as they fin- ished. Out of the 29 that finished within the time limit (four hours, fifteen minutes) 5 presented heart conditions. Table 16 shows the place in which they finished. The fourth column in Table 16 shows the pro- portion of the pulse-pressure after the race to that before.
