had discovered the constancy of interfacial angles; and, using a contact
goniometer invented for the purpose, he had made measurements of the
interfacial angles (exact to about half a degree) of each mineral that Romé
listed. Both these aspects – the tabulation of primitive forms and the measurement
of interfacial angles – were of central importance to Romé’s crystallography…
Romé’s chief scientific goal was the establishment of mineralogy
on a firm basis of crystallography. His major contribution toward this end
was the formulation of the law of the constancy of interfacial angles which
became the cornerstone of crystallography. Although earlier investigators –
including Hooke, Erasmus Bartholin, Steno, Huygens, Philippe de la Hire
and Guglielmini – had made incidental statements about such a constancy
in one or two substances, Carangeot and Romé were the first to enunciate
it as a general law of nature« (DSB). – Drei Blätter mit hinterlegten
