of the nocturnal type is endemic in the kampung areas of Djakarta. In a representative area the filarial infection rate of 4,311 persons resident there for at least 3 years was 10.4 per cent. Men showed somewhat more infection than women, but the difference was not significant. The number of microfilariae found in the blood was usually small, the average infection being 28.3 microfilariae in 20 mm of blood, but the microfilarial count was 10 or less in more than 45 per cent of the cases.

In the area examined no elephantiasis was found. Generally it is rarely seen in Djakarta. On the other hand, hydrocele was found in 14 of the 92 men (15.2%) examined above 15 years of age. The youngest person showing hydrocele was 20 years of age. Thickening of the spermatic cord was found five times. The youngest person showing this abnormality was 14 years of age.

Lymph-node enlargement was frequently found in both men and women, but there is no certainty as to the etiology of these enlargements.
