As it is shown in previous papers, that Nukada's law concering whooping cough is so interesting, the author wanted to know, whether this law was applicable to the incidence of measles. It is very interesting, that Nukada's law is recognizab e very slightely concerning incidence from measles. The author supposed, that this difference between whooping cough and measles was due tothe differencein mother's susceptibility. Mothers of measles patients are rarely affecteted by measles, while mothers of whooping cough patients often suffer from whooping cough.
An abridged life table was constructed for emplyees and their families of Miike Coal Mine, Omuta, Fukuoka Prefecture, living in the company's residences in 1948. The population as of July 1, 1948, was estimated from the populations as of Dec. 31, 1947 and 1948. The deaths were surveyed by public health nurses visiting each family and checked by the death registrations and the hospital records. Accident deaths were separated and two kinds of life tables for the total deaths and those excluding accident deaths were constructed for the males. The result is shown in the table attached. The remarkable features indicated in it are as follows : 1) The infant mortality is very low, male 0.0714, female 0.0427. 2) For males, q?, is higher than q, due probably to the low birth rate in 1945 and 1946 and to the reduced deaths of children of one year old. 3) The complete expectation of life at birth is very long, male 50.77 years and female 60.19 years, mainly due to the low infant mortality. 4) When the accident deaths were excluded, the male ej is extended to 53.40 years.
