    1. Breath-holding test was applied both under ordinary and under-water conditions to the same subjects, and the breath-holding time, CO1 content and O2 content of the alveolar air were determined in each subject
    2. For collecting the sample of the alveolar air, a modified collecting tube was designed, making it more suitable for a field work.
    3. In primary school children, the breath-holding time increases with the age both under ordinary and under-water conditions. The longer breath-holding time is accompanied with increased CO2 content of the alveolar air after the test.
    4. Generally speaking, breath can be held longer under ordinary conditions than under the water. Here also the longer breath-holding is accompanied with greater CO2 content of the alveolar air after the test.
    5. The age difference in the breath-holding time may be due to the sensitivity and/or the volitional effort of endurance.
    6. For the shorter endurance in the. under-water breath-holding, not only psychological, but also technical factors on the part of the tested subject may be responsible.

    1. Gas analysis of the cubital vein blood, plethysmography of the finger and the fore-arm, and blood pressure measurement on the brachial artery were performed during the breath-holding test. Cutaneous blood capillaries in the nail-bed were also observed.
    2. Breath-holding resulted in the increase in O2 content and decrease in CO2 content of the cubital vein blood. This decrease in venosity in the upper limb is explained by assuming a substantial utilization of the arterio-venous anastomosis by the circulating blood in the upper limb.
    3. The breath-holding is accompanied by the contraction of blood vessels in the skin and the muscle. This vasomotor effect, obviously of central nature, serves to shunt off the locomotor organ and to avoid a drastic decrease in the oxygen supply to vegetative organs.
    4. The breath-holding causes elevation of both the systolic and the diastolic blood pressure, reaching their highest values directly after the interruption of the breath-holding. In a group of, subject, a transitory increase of the finger volume was observed, which was interpreted as produced by marked elevation of the arterial blood pressure.

    1. The breath-holding test was repeated every other day, and the training effect was followed up, determing breath-holding time, time for the commencement of intrathoracic respiration, expiration volume and gaseous composition of the alveolar air.
    2. Repeated performance of the breath-holding test caused prolongation of the breath-holding time. Its maximum development was reached by the 4th to 8th repetition to remain on the same level, even after the interruption of the training for 9 months.
    3. Time of commencement of the intrathoracic respiration remained on the same level from the first performance to the last, without significant change despite the training.
    4. It was revealed that there was a optimum quantity tsf the inspiratory volume for each subject to perform the intrathoracic respiration. Subjects appeared to learn in the course of the training to adjust his volume of inspiration directly before the test performance.
    5. Prolongation of the breath-holding time by training is attributable mostly to the increase of the volitional endurance duration of the intrathoracic respiration. During the earlier period the technical improvement contributes to the training effect. It is not clear whether there occurs a gradual decrease in the excitability of the respiratory centre.

    1. Migration by marriage into families in 7 communities comprising the eastern part of Upper Ina District, Nagano Prefecture was studied. In the average for 6 villages, matrimonial immigration from outside into the village covered 30% of the married couple. The rest was the marriage within each village.
    2. Marriage circle was found somewhat larger for lower, more level localities than typical highland villages. Definite relation exists between the facilities of communication and transportation and the size of the marriage circle. More urbanized places, namely, showed so much larger marriage circles.
    3. Frequency of consanguineous marriage was shown higher in villages with narrower marriage circles. Marriage circle for consanguineous marriages was found smaller than that for non-consanguineous ones. Villages with higher consanguineous marriage circle also possess parallelly higher non-consanguineous marriage circle.
    4. Flow in the matrimonial migration was shown directed primarily from less developed to more developed parts and secondarily from poorer to richer localities.

    1. Since the forthcoming reports are based on the survey concerning the feature and activity of the Peachboy and of other characters of the tale, an effort was made to identify the text of the tale as remembered by the children subjected to the survey.
    2. The source from which the children bad aquired the tale was firstly picture-books, secondly the mother and thirdly the father.
    3. Texts of the tale as supplied by 183 college students from their memory showed various differences in each point. They were analyzed and the most popular form of the tale was formulated.
    4. To the children under school-age, a specified form of the tale was told immediately before the survey. But the detailed specifications concerning the particular points to be taken up in the survey were carefully omitted from the narration.
