Stated in the following are the results of the clinical observations made on the basal body temparature curves of the pupils (40 in Tokyo and 14 in Okinawa) in nurses' Schools by the use of common thermometer by arm pit method covering a period of total 119 cycles.
1. Body temperature curves were classified into 6 kinds by the nature of the high temparature phase including the typical biphasic curve and the monophasic curve and, further, they were classified into 4 groups by the difficulty in determining their types.
2. Typical monophasic curve occupied only 12% of the pupils in Tokyo, while it was 34% in Okinawa which was due to the younger age of the pupils in Tokyo.
3. Monophasic curve, or the curve in which the elevation of body temparature was recognized only for a short period immediately before the initiation of menstrual period (types V-VI) occupied 57.4% in Tokyo, while it was only 2.2% in Okinawa which was also due to the younger age of the pupils in Tokyo.
4. Curves of the inconsistent type (types II-IV) occupied 10.6% in Tokyo and 20.7% in Okinawa.
5. When observed by the length of the cycle, those who showed excessively short cycles being within 24 days and those who showed excessively long cycles being over 36 days were mostly among the types V and VI.
6. Group A curves, namely, the curves with clearly distinct types occupied 41.4% in Tokyo and 54% in Okinawa. Group A' curves, namely, the curves with poorly distinct types occupied 34.6% in Tokyo and 39% in Okinawa. B curves which would become distinct after due adjustment occupied 16% in Tokyo and 7% in Okinawa. Group C curves with indistinct types occupied 6 % in Tokyo, but none in Okinawa.
7. Period of the elevation in the basal body temparature was 1-4 days in most cases. The average of this period in Tokyo was 3.27 days and 1.8 days in Okinawa.
8. Duration of the high temparature phase was mostly 11-16 days in both Tokyo and Okinawa.
