KONSEN-GENYA, the eastern part of Hokkaido, extended from Nemuro Province to Kushiro Province, is often called an undeveloped treasury and thedevelopment is being keenly watched by the public from the present circumstances of Japan. The fundamental problem of the cultivation is the hygienic condition of people who come to cultivate as novices. For the purpose, it is necessary to investigate the life of people who have started reclamation in this area. These results are as follows : 1. Most of them had been people inexperienced of dairy farming before thiscultivation and we ought to expect the same from further recruits yet to join. 2. It is noticeable that the immigrants have infants or babies handicapping their activity, when they are inevitably hard workers. 3. The first stage of the labour for finishing 50% of cultivation generally takes 3 or 4 years. 4. If their method of cultivation sould be continued, it is necessary to give them some facility for recreation, because their labour of the first stage are very hard, 5. It is desirable that a radio etc. may be used as important means of the education for them. 6. The investigation about their housing, nutrition and children were also carried out. 7. In the centre of the problem, there is food problem, egh how to powder the grain and to preserve it and other food material for winter. This will bedealt with in a separate report, which will soon follow.
Quick repetitive motion was examined in 10 children of 5 years and 16 children of 6 years by means of a tapping enumerator. Using their right hand they regularly had a daily practice, consisting of 5 practices of 10 secons each repeated with an interval of 1 minute. The first practice period had a length of two weeks excepting Sundays. Af ter two weeks' rest perlod came the second practice period of one week. The third and the fourth practice periods, each of a week, were also applied after two weeks' rest from the preceding period of practice. Some of the results worth of recording are as follows : (1) E -ect of practice was remarkable during the first 6 days, acquiring 112. 1/3 of the whole frequency increment gained in the whole period of practice stretching over about 3 months. (ii) In 5-year children, interruption of practice tended to reduce the acquired extra-achievement. With the repetition of practice, however, the p -actice effect tended to persist. Great individual difference was observed in this respect. (iii) Practice with the right hand, not only enhanced achievement with the right hand, but also improved the left hand, though in a slighter degree i. e. by 7 %. (iv) Averge tapping frequency before and after the practice is as follows : Tappings for 10 sec. The values after the practice correspond to those of 5-6 th grade children of elementary schools. (v) When the same children were examined for remote effect in the 2 rid grade, they were found to retain the motor ability acquired by our practice 32 or 20 months previously. Their results are superior to those of other groups without experience of our practice. There was a statistically significant difference
Thirty children of normal vision, male and female, from the 6 th grade and 27 blind children from the 5th and 6th grades were examined, immediately prior to lunch, with carrot dishes of different cutting, cooking and dressing. Although carrot is disliked by most children, the present study showed that they take some kinds of carrot dishes quite willingly. For instance, tempura is liked by most children.
The postural blood pressure reflex was examined on fifty patients of pulmonary tuberculosis, 32 males and 18 females, 21 to 57 years of age, now being taken care of in a sanatorium. In the present study, mainly the fluctuations of the maximum blood pressure points were analyzed. In summary, it was fou ld that the brachial blood pressure declined in 22 patients (44%) after the posture change from sitting to lying, and in case of posture change from lying to sitting, 33 patients (66%) showed insufficent restoration of the blood pressure. In view of these facts, it is supposed that the regulatory ability of the blood pressure in pulmonary tuberculosis patients is insufficent, compared with that of healthy subjects. The fluctuation and restoration curves of the blood pressure, to some degree, seems to be determined by age, and generally speaking, the older the patients are, the more likely they are to show an abnor. mal fluctuation of the blood pressure. the
