    In the usual life table the number of survivals lx at age x, starting from the original number l0, 100, 030 or 10, 000 at birth is tabulated. If we designate the ratio lx+n/lx x 100 (n=1, 2, 3, ) as survival ratio, this indicates the proportion of persons reaching (x+n) years of age among persons who reached x years of age. And the magnitude of this ratio depends on the magnitude of deaths in the age interval between x and (x+n). If persons in the age interval are healthy, the number of deaths would be small, and the ratio lx+n/lxwould consequently be large. Hence the ratio may serve as an adequate indicator of the healthiness of persons in that age interval.
    From this point of view, all kinds of ratios were computed using six Life Tables of Japanese so far published, x being changed from 0 to 80, and n from 1 to 90.
    An abstract of the result is shown in Table I and II anddepicted in Fig. I-V. How the ratios change with age and interval may be clearwithout any further explanation.

    La autoro studis proporcion de fataleco de morbilo lau lastatistiko de Ministrejo de Publika Higieno, kaj konkludis kiel jene :
    1) La estimata nombro de pacientoj estas 185-obla de raportita nombro de mortintoj de morbilo.
    Tio signifas, nur unu de 13-19 morbilaj pacientoj vizitaskuraciston, au estas raportata kiel paciento. Aliaj pacientoj ne vizitas kuraciston, au estas ne raportataj per kuracisto. Tiamaniere la proporcio de fataleco shajnas tre granda.
    2) La raportado estas pli bona en 1949 ol en 1947.
    3) La proporcio de fataleco en Hokkaido kaj Tohoku distrikto estas phi granda ol suda distrikto.

    La autoro komparis kurvojn de morbilaj pacientoj de 13 lernejoj de Jokosuka Urbo, kaj trovis, ke la plej altaj punktoj de kurvoj movighis de unu lernejo al aliaj. Li konkludis, ke la epidemio de morbilo movighis de unu loko al alia.

    1. La autoro studis ciklan variadon de morbilo de pasinta tempo en Jokosuka Urbo lau la anamnezo de lernantoj kaj iliaj gefratoj. La periodo shajnis 2 jaroj. Sed la amplitudo estis tre mallargha. Tio devenis de malekzakta memoro.
    2. La autoro studis ankau ciklan variadon de morbilaj pacientoj lau la statistiko de Ministrejo de Publika Higieno, kaj konkludis kiel jene :
    1) La periodo kaj la amplitudo de cikla variado de morbilaj pacientoj de tuta lando konformighis kun ili cfe morbilaj mortintoj.
    2) En Hokkaido, Tohoku kaj Hokuriku distriktoj estis la amplitudo de variado mallargha, sed en prefektejoj, kio enhavas grandan urbon, tre largha.
    3) La epidemio de morbilo ne okazis samtempe, sed la propagha jaro estis malsama je prefektejoj, char la periodo de variado estis m3lsama.
    4) En la distriktoj, kie denseco de loghantoj estis grandaj, estis amplitudo de cikla variado largha.
    3. La autoro konis, ke la memoro pH tempo de morbila malsanigo, estis tre malekzakta, sed ke la fakto de malsanigho mem estis bone memotata de gepatroj.

    By Y. Kubota, K. Hukuda, F. Ishihara, M. Furukawa and Y. Shiba
    Almost all the inhabitants of thirty one communities in the Upper Ina District, Nagano Prefecture, were subjected to a systematic survey. There were 4, 891 families of consanguineous marriage among 30, 984, couples, i. e. amounting to 15.79%, of which
    9.88% were cousin marriages,
    1.71% marriages between children of cousins and cousins,
    4.19% marriages between second cousins.
    Eugenic Index of Inbreeding of the population, when expressed on the cousin marriage level, was as follows:
    0.0988+0.0171/2+0.0419/4=0.1178
    This index, proposed by the senior author (K.H.), refers to the degree of risk apprehended on the ground of race hygiene, especiany when a simple recessive gene exists in the population. When there are no other types of consanguineous marriage than cousin marriages, their frequency corresponds to the index. When there are consanguineous marriages more remote, their frequency contribute, with due reduction, to the index of inbreeding.
    Kawashima Village has the highest rate of consanguineous marriage, i. e. 28.4 (= 16.43 +3.62+8.21) %. The Eugeie Index of Inbreceding amounts to 0.2029. The community with the lowest rate of consanguineous marriage is Takatoo Town, which still has 9.5 (=6.65+1.21+1.66) S. The Index of Inbreeding, 0.0767, is still very high.
    Result of further analysis will follow in separate papers.
