The energic metabolism of many kinds of industrial activities has been already observed. butthe report about the relative metabolic rate (R. M. R) of the textile works is very few. The R. M. R. of all sorts of the textile female workers were studied in a certain textile shed in July, August and September, 1952. The activity of workers in the textile shed is generally light and it is continued with a sdeady state, but without constant speed. The rather wide variation of R. M. R. in the same department is considered to be due to varied elements of activities involved. The larger values of R. M. R. were found among weaving (1.6-3.6), packing (2.1-3, 1), refining (1, 3-2, 0), mule working (1, 3-2, 0), and parading especially beating (1, 3-2, 0).
The basal metabolic rates of 89 national safety men with an average age of about 21 years were measured in november and december 1952. The results are given in table 1-4. The average basal metabolic rate per hour per square meter of the artillery (22 men), of the tank men (10 men), of the engineer (37 men) and of the infantry (20 men) were 42.1, 42.0, 41.5 and 42.5 calories respectively. The total average B. M. R. of all subjects was 41.9cals./hr./sq.m. (table 5). This rata is 13. 5 percent higher than Japanese standard value 36.8 calories of the same age range.
In continuance with the first report about Longevity, the authorp investigated the nutritional status of the two villages in Chiba Prefecture, one of which, Nishizaki village, is of high longevity and the other Shoei village, is of low in this Prefecture. As to the result of the food investigation, the amonuts of Calories, protein and fat taken by the villagers of Nishisaki are larger than those of the Sohoei villagers, but about the other nutrients, vitamines and minerals, there is little discrepancy to be found between two villages. Their physical growth in Nishizaki village is alss found to be a little beter than that in the other village. There are considerably many patients of nutritive diseases in both villages, and when compared with the two villages, percentage in Nishizaki is higher.
A statistical survey was done on 128 old people in a certain village in Chiba Prefecture about their living circumstances, dietary, foods and health, which are generally considered to have much to do with longevity.
