(2) errors are constant whatever the speed;
(3) constant errors are positive showing overruling in all cases;
(4) there is no disturbance created by the second-hand movement, save for r.h.e.c. mean errors, where the accuracy is less for the compound records; this is probably due to the fact that this record shows the least evidence of voluntary control, and is thus most subject to disturbances;
(5) there is a marked reduction of mean error 20-50 beats, probably due to practice.
For individual cases note:
(1) fatigue-spots for non-visual mean errors only;
(2) the equality of result of both types of movements is noted for all cases;
(3) the non-visual right-hand records for some subjects are more accurate;
(4) the more trained hand is not, as a rule and subject to exceptions, the more accurate one, especially for the non-visual records; and
