    A large number of the first metaphase figures in a number of testis specimens obtained from the Japanese males in Japan were studied. The results of our analyses indicate the existence of three different types of heteromorphic paires of chromosomes in some of the specimens. These were described in details and cytogenetic as well as the anthropological significance of these chromosomes is discussed briefly.

    Clinical observations on Type-B Japanese encephalitit in 1953 were carrid out at Manji hospital in Yokohama. The epidemic in this year was comparatively mild falling between the violent epidemic cycles which occur every other years. Of 35 suspected cases (from thirtieth July to eleventhOctober) 27 were positvely diagnosed, the number of the true cases corresponding only to one-third of the previous year. Generally, the courses of encephalitis in this year were rather mild, and there was no case with maniac symptoms. Serum complement-fixation tests were negative in 25% of the cases. Of 27cases, 6 died, the mortality being 22%. Almost all of those with extreme disturbance of consciousness and of those with high fever over 41°C died. In the cases where muscular spasms were frequent and those with long continued low fever were observed to manifest sequela.

    In the studies of diagnosis of pneumoconiosis, 533 cases inhalating mineral dust in high and low concentrations were examined. The distribution of the nodular shadows due to pneumoconiosis was studied by comparing the International Standard of Radiological Classification of Pneumoconiosis, adopted in the third International Conference of Pneumoconiosis, with Oka's classification which we had previously used. Even in the earliest stage the nodular shadows were seen in the outer one-third of the lung field in most of the cases. For this reason it is believed that further study is required befor the degree of pneumoconiosis can be determined chiefly by the distribution areas of the nodular shadows. Furthermore, the size of the nodular shadows, in the cases of low concentration-inhalation was not proportional to the number of working years under mineral dust. The number of the shadws, but not the size, increased in a greater part of the cases, and the progress to the end of the “first degree” was comparatively rapid, few reaching the “second degree”. However, the rapidity of the development of the disease was observed to be influenced by individual differences. The pleural adhesions were mostly noticed in those with tuberculous findings. Bleb-formation of emphysema was seen in the comparatively early stages. The size of the destinction-shadows due to pneumoconiosis in the hilum lymph nodes were mostly two or three centimeters.
