By the method of Mantoux and Roux, the present author gave the intracutaneous tuberculin injection upon 2151 school children of Ibaraki Prefecture, and reported the results of the test last year. Now I will append to that report with the results of test given on 1218 school children of the special elementary schools in Mito City-and of elementary schools in farm-village. The test was given in the following manner. By the method of Mantoux and Roux, I gave the intracutaneous injection. The tuberculin that used was the dilution of 2000 times of an old preparation. Forty eight hours after the text. Moreover, the author classified the nutritional state of the children according to Prof. Miyagawa's method, and then examined the relationschip between the tuberculin reaction with the state of nutrition. The r e sults of present study are as follows:-
1) The percentage of positive reactors to th e intracutaneous tuberculin test was 22.37% in the special elementary schools in Mito City and 9.87% in the elementa ry schools in farm-village.
2) The former showed the highest percentage of the tests which was hither to given and, on the contrary, the latter was the lowest, which is less than half of the results in other schools.
3) The rate o f positive reactors increases almost proportionally with age advances.
4) There seems no significanse in the sex difference.
5) Although I recognize the exsistence of no special relation between the tuberculin reactors with the state of nutrition, the rate of positive reactors some what inclines as the nutritional state becomes better.
