Abstract
DURING an examination of polished sections from Prof. A. M. Bateman's collection of Indian manganese made during his trip in 1954 (1232a, Joda East Nagpur), I noticed a few grains of a greyish white mineral with a distinct yellow tint and a slightly greater hardness than braunite, with which it is associated. Etch tests with nitric acid, potassium cyanide, stannous chloride and hydrogen peroxide were negative. Microchemical tests indicated the presence of manganese and iron. X-ray photographs of the mineral were taken by the Debye–Scherrer method using iron K radiation. The d spacings observed from the film, as given in Table 1, agree fairly well with the values obtained by Fleischer and Richmond1 for bixbyite from the Thomas Range in Utah.
