Sentence:  The close ratio of ferric oxide to titanic oxide, viz., 1:3·03, indicates that the mineral is really ferric metatitanate, Fe<sub>2</sub>O<sub>3</sub>.3TiO<sub>2</sub> or Fe<sub>2</sub>Ti<sub>3</sub>O<sub>9</sub>. Moreover, the crystallographic determinations strengthen the view that this titanate of iron cannot be assigned to any known species, but is entirely new. I propose to name it <WSD>"Arizonite</WSD>"... There appears to be no authentic prior record of the occurrence in nature of a simple ferric metatitanate... Upon readjustment of the analytical data as cited by Rammelsberg, it appears that his mineral consists essentially of 60 per cent ferrous titanate (FeO.TiO<sub>2</sub>), ilmenite, and 40 per cent ferric titanate (Fe<sub>2</sub>O<sub>3</sub>.3TiO<sub>2</sub>), <WSD>arizonite</WSD>. 
Meaning of the word marked with <WSD> tags:  A titanate of iron, Fe<sub>2</sub>Ti<sub>3</sub>O<sub>9</sub>.
