Title | Unpublished paper, 'The structural arrangement of the mineral matters in sedimentary and crystalline pearls' by George Harley |
Date | 1889 |
Description | Harley begins by presenting an overview of existing literature on pearl structure, pointing out that since Rondelet threw out the idea that pearls are merely diseased concretions occurring in the Mollusca in the same way as 'other morbid calculi' occur in the Mammalia, and Réaumur said they are misplaced pieces of organised shell, the opinions of subsequent writers have but oscillated between these two theories. Harley considers whether pearls belong to the animal or mineral kingdom, and presents observations on microscopic sections of crystalline pearls.
Annotations in ink throughout. Includes five pages of figures showing the structural arrangement of the mineral matters in sedimentary and crystalline pearls.
