Tinea versicolor infections made up about one-fourtli of the skin diseases 

 observed. Tlie affection (see Plate XVII, fig. 2) is noteworthy only on account 

 of its slight disfigurement. In this connection it should be stated that in one- 

 half of the ca.ses the lesions were situated on the face and were thus e.\posed to 

 light in contradistinction to the usual location in temperate climates. The 

 frequent occurrence of the lesion on the face of natives of the tropics has been 

 noted in Assam by Powell and others. The disease is especially noticeable in 

 the young of both sexes { 16 per cent of males and 9 per cent of females being 

 affected). In many cases the lesions were extensive. The best antiseptic treat- 

 ment seems to be sulphurous acid generated directly upon the skin by applying 

 fii'st a 10 per cent solution of sodium hyposulphite and then a second solution of 

 5 per cent tartaric acid. 



Tinea circinata was less j)revalent in Taytay than in Manila. The region 

 around the groin is seldom attacked probably on account of tlie loose clothes 

 worn. Most of the cases .seen in Taytay showed only small ])atches on the wrists 

 and waist. 



Scabies (Plate XVII. fig. 1) was found to be very common, attecting 8 per 

 cent of the jMipulation. However, no special attention is paid to it by the natives. 

 They know the organism which causes the infection and frequently extract it on 

 a needle for the sake of curiosity. Nothing particular was noticed about the 

 disease except that it seemed to be the starting point for impetigo contagiosa 

 in children and sometimes it was difficult to separate the lesions in a mixed case. 



hnpetigo eon1a<jiosa was very common among young children and gave many 

 of them a repulsive appearance by producing crusts over the head and face and 

 often over the entire body. Sfaphylocovvs pyogenes aureus in pure culture 

 was isolated from 3 cases. Several cases of infected glands were found at the 

 base of infected scalps. The lesions or scars of this disea.se. together with those of
