The temperature of the two halves 338 Walter E. Garrey. is approximately the same. The results of this experiment are shownin Table I. It is thus seen that the ratio of the rhythm of right to that of leftside (in this experiment averaging ), remains quite constant,while the actual rates vary from per minute to 60 per R MfmwwmmNmNmm
