M. H. NATHANSON, M.D., ARCH. INT. MED. 54:111 (JULY) 1934.
The legend for figure 4 (page 118), beginning with the second sentence, should read: B, C and D were taken after the intravenous injection of 0.2 mg. of l-epinephrine. B shows a maximum rate of 100 with multiple rhythmic foci. E was taken twenty-five minutes after the injection.
In the legend for figure 7 the figure referred to in the last line is 4 rather than 8.
