39 — Skin diseases. The 142 cases of skin disease were made up as follows: .. 50% .. 20% Late syphilis or Yaws Scabies Eczema Vitiligo Other skin infections 10% 10% 10% As has been said before it is impossible in most cases to distinguish in children at least the difference between a late yaw dermatitis and one due to congenital or tertiary syphilis.

Scabies is a fairly common infection especially in parts of the country where natives are beginning to wear more clothes. Sulphur ointment is keenly sought after as its beneficial effect seems to be appreciable.

Eczema is fairly widely met with generally throughout the tribe apparently owing its origin in most cases to conditions like sweating, and to irritating messes applied to the skin.

Vitiligo is found affecting chiefly the extremities, especially the lower. In very few cases did the leucoderma extend on to the body. Many of the cases are I think due to late yaws.

Among “ other diseases are included a certain number of mycotic derma¬ titis. It is hoped that microscopic work in the field during the remainder of the survey will permit of a more definite classification of these. Some cases of nodular dermatitis (the so called craw-craw) are also included.

Wounds and other injuries. Type of wounds usually met with are spearwounds, contusions, burns and abrasions. The last named occurring on the skin are rather important as a starting place of ulcers which by neglect are apt latterly to become a very incapacitating disability. In this column are included ten cases of congenital deformity consisting of three cases of double hare lip, two being brothers, three cases of deformity of the spine, one case of congenital deaf¬ ness and the remainder affections of the limbs.

Tumours. Eleven cases only of tumour were found :— Their analysis is as follows :— Benign — Adenmata of thyroid Cvstie tumours of female breast Tumour of uterus Malignant —Carcinoma of female breast Carcinoma of male breast (?) Secondary nodules on liver 5 9 8 1 1 1 Total 11 The low incidence of malignant tumour is remarkable, but would appear to be a general finding amongst all primitive races.

Gynaecology. Two cases only of endometritis presented themselves for treatment. Diseases of women would appear to be very rare in the tribe.

Tropical diseases : — Dysentery. Of the seven cases found only one was amoebic, contracted at Malakal and six were bacillary. The bacillary cases were all sporadic in origin and subacute or chronic in character. Clinically they were apparently Flexner infections.
