By means of igneous fusion the authors have succeeded in reproducing two types of crystalline associations, which, in their mineralogical composition and the principal features of their structure, are analogous, if not identical with certain oligosideric meteorites. The only notable difference results from the habitual brecchoid state of the meteorites, which contrasts with state of quiet solidification of the artificial compounds. - F. Fouqué and Michel Lévy.
