† thorina Chem. Obs.|θɒˈraɪnə|
[ad. F. thorine, 1817, a bad representation of Berzelius's name Thorjord, Ger. Thorerde: see thoria.
In the Annales de Chemie, etc. 1817, V. 5, the form thorine is erroneously attributed to Berzelius himself (‘une nouvelle terre à laquelle M. Berzelius a donné le nome de thorine’). Misled by this, English chemists long used thorina and thorinum for thoria and thorium.]
1. The name given at first to a substance found by Berzelius in 1815 in various Swedish and Norwegian minerals, and named by him Thorjord, which afterwards proved to be yttrium phosphate.
1818W. Phillips Outl. Min. & Geol. (ed. 3) 29 The discovery of a new Earth by Berzelius a Swedish Chemist, has lately been announced... This earth has been named..Thorina, from the Scandinavian deity Thor. 1826Henry Elem. Chem. II. 695 A farther investigation by Berzelius of the substance to which, in 1815, he had given the name of Thorina [ought to be Thorjord].., has now satisfied him that it is merely a sub-phosphate of yttria.
2. The name formerly given to the earth or oxide to which Berzelius in 1828 transferred the name Thorjord, now called thoria.
