1. The average iodine number of human milk fat from 260 samples was 58.6. The maximum and the minimum were 85.7 and 35.4 respectively (Cf. Table 7).
2. The iodine number of human milk fat becomes higher with weakening of Arakawa's reaction. The average of Arakawa-positive milk and that of completely (or almost completely) negative milk was 51.8 and 64.7 respectively. That of milk of intermediate reaction-60.3-comes between these extremities (Cf. Table 7).
3. 87% of Arakawa-positive cases have the iodine number below 60.0, while only 27% of completely Arakawa-negative cases have the same value. And 50% of intermediate reaction (or 66% of the better intermediate and 42% of the worse intermediate) have the iodine number below 60.0.
4. From the data of the present investigation alone, one cannot say whether there is a significant variation of the iodine number according to the season of a year.
5. It seems that in general late milk is high in the iodine number.
6. The iodine number of human milk fat seems to be high in milk secreted from very young mothers and aged ones.
7. The iodine number of milk fat was higher in general on the weaker side of Arakawa's reaction in one and the same mothers who had different Arakawa's reaction on different sides of the breast.
8. In the cases of one and the same mothers with very different reaction on different sides of the breast, the negative side milk showed a higher iodine number of milk fat without a single exception.
9. Generally and roughly the iodine number of human milk fat becomes higher with increase of fat content of milk.
10. The present report is within my knowledge the first paper dealing with the nature of human milk fat and vitamin B1 deficiency of lactating mothers.
