No 863 ( english ed. 1672 ) :" This celebrated treatise, justly called by Fulton p. 67 ' The beginning of the modern development in knowledge of crystal structure', really has little to do with gemstones except as they happened to conveniently provide crystals for Boyle's inquiries into the solid state of matter. One of the principal reasons for writing this work, accodring to Boyle, was to determine if the use of pulverized gemstones, still recommended as curative ingredients in medicine, had any basis in chemical fact."
