1845. Amer. Jrnl. Sci., LXVIII. 219. Tenorite.—This name, in honor of a distinguished Neopolitan botanist, has been given to the black oxyd of copper by M. S. Semmola, who has found the mineral crystallized among the scoriaceous lavas of Vesuvius.
1865. Maskelyne, Athenæum, No. 1980. 473/3. Crystallised Melaconite and Tenorite.
1868. Dana, Min., 804. As the names tenorite and melaconite were given the same year, and tenorite was made non-isometric (hexagonal) by its describer, it appears to be right that tenorite should be sustained for the above mineral, and melaconite be left for the isometric kind, if any such proves to be a native species.
