The file consists of 18 b&w glass slides of Chinese patients with leprosy (Hansen's disease), taken from 1922 to 1932 on D'Arcy Island and Bentinck Island. The file also has one slide of the patient cottages on Bentinck Island. The slides were made from the related negatives and show patients standing or sitting and were often taken at admission and after progression of the disease. Some of the photographs are close ups of hands, back, legs and feet. The slides are arranged in numerical order in accordance with the list of leprosy cases, created by the Provincial Health Officer (copy stored with negatives).
