Conchite, a new Form of Calcium Carbonate1
Published online by Cambridge University Press: 14 March 2018
Extract
In the course of an investigation on calcareous secretions in the animal kingdom, and more particularly on molluscan shells, I found that the latter did not consist of aragonite, as G. Rose and Sorby had supposed, but of a negative, uniaxial mineral, which is distinguished by most of its properties from calcite, and for which I propose the name conchite (KóγXη, shell). I further found that conehite occurred naturally in many localities--always as a crystal aggregate. Its properties were investigated on such, as well as on the eonchite in shells.
