Periodic fluctuations (slow rhythms) were detected from the time series of respiration and pulse intervals of untreated prone position rabbits, by means of moving average and serial correlation coefficient. The examination on maintenance, occurrence and periods of slow rhythms were described. 1. No changes of slow rhythms of respiration and pulse intervals were recognized in respect to number of components within 30 minutes ; therefore, one can plan to perform an experiment under control at least within this length of time. 2. The slow rhythms, which were detected directly from the correlograms of the original series, were of highly regular and were the most dominant component among the frequency components composed of the original series. 3. Frequency distribution figures were drawn with the periods of slow rhythms found in respiration and pulse intervals. The figure showed a distribution which is unimodal in the group having comparatively higher regularity and is bimodal in the groups including almost all of the slow rhythms.
