Excerpt from Petrographical Tables: An Aid to the Microscopical Determination of Rock-Forming Minerals
The mean index of refraction is n 2 E denotes the apparent optic axial angle, or angle between the Optic axes measured in air.
The expression p v (under the head of dispersion) indicates that the Optic axial angle for red rays is smaller than that for violet p v that it is greater)

Paperback. Condizione: New. Print on Demand. This book translates Professor Rosenbusch's German work on identifying minerals within rock compositions into English. It includes an index to aid in locating specific information within the book's tables. The book's tables provide information on the optical and crystallographic properties of minerals, including their refraction indices, optic axial angles, and orientation. The book's data was determined through laboratory experiments conducted by the author. These experiments focused on analyzing the minerals monazite and mosandrite, providing valuable insights into their compositions and properties. By presenting this data, this book serves as a valuable resource for researchers and students interested in the field of mineralogy. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
