The author collected the data of the family history from the sick-bed records at the Kanagawa Tuberculous Sanatorium and estimated the familial death rate with tuberculosis for one year. After comparing the death rate of the family with that of the population, taken from official statistics published annually by the government, the author recognized that the rate of the former is greater than that of the latter, so that he confirmed the familiarity of tuberculosis.
