TitleUnpublished paper, 'Aperçu sur une manière nouvelle d'envisager la théorie cristallographique' [Sketch of a new manner of considering the theory of crystallography] by L A Necker
CreatorNecker; L A (fl 1839)
DateJanuary 1839
DescriptionNecker suggests that there should be different forms of molecules, some spherical, some elliptical with two equal axes, and a third unequal to these, and others elliptical with three unequal axes. He explains that a Mr. Dana is the only mineralogist who has attempted to introduce into crystallography the consideration of molecules with curved surfaces; however, the most important and difficult steps in this branch of physical science still remain to be made, and many phenomena in crystallization still require explanation through theory. Necker particularly refers to facts discovered by M M Leblanc and [François Sulpice] Beudant.

The paper is written in French, followed by an English translation. Annotations in ink throughout.
