Happening to let fall a specimen of calcareous spar belonging to a friend, he was led by examination of the fragments to make experiments which resulted in the statement of the geometrical See also:law of See also:crystallization associated with his name (see See also:CRYSTALLOGRAPHY) . The value of this See also:discovery, the mathematical theory of which is given by Hauy in his Traite de mineralogie, was immediately recognized, and when communicated to the See also:Academy, it secured for its author a See also:place in that society .

The following are his See also:principal See also:works: Essai d'une theorie sur la structure See also:des cristaux (1784); Exposition raisonnee de la theorie de l'electricite et du magnetisme, d'apres See also:les principes d'See also:Aepinus (1787); De la structure consideree comme caractere distinctif des mineraux (1793); Exposition abregee' de la theorie de la structure des cristaux (1793); Extrait d'un traite elementaire de mineralogie (1797); Traite de mineralogie (4 vols., 18oi); Traite elementaire de physique (2 vols., 1803, 'Sob); Tableau comparatif des resultats de la cristallographie, et de l'analyse chirnique relativement a la See also:classification des mineraux (1809); Traite des pierres precieuses (1817); Traite de cristallographie (2 vols., 1822) .
