Min. [a. Fr. amphigène, f. Gr. ἀμφιγενής of both kinds, of doubtful kind; f. ἀμφί both + γένος kind, nature.] A synonym of LEUCITE, rejected by Dana.
1803. Edin. Rev., III. 53. Now we see its [leucite’s] place supplied by the word amphigene.
1868. Dana, Min., 335. Haüy’s name, Amphigene, is … in allusion to the existence of cleavage in two directions (which is not a fact), and to his inference therefrom of ‘two primitive forms’ (which is only a notion of his); and it has therefore the best of claims for rejection.
1869. Phillips, Vesuv., x. 292. Leucite or Amphigene, frequent in the lavas of Somma.
