Description: Rutile sixling (idealized drawing) Graves Mountain, Georgia USA From G. H. Williams (1890), "Elements of Crystallography," Henry Holt Publishers (New York), p. 198, as reproduced in "Annual Report of the Geological Survey of Arkansas for 1890," vol. 2 (1891), p. 325. Note Williams' use of the term "sixling." This idealized drawing originally appeared in Professor Rose's 1862 article, and was attributed to Graves Mountain, not Magnet Cove as Williams reported. Over the past 150 years, countless adaptations of Gustav Rose's idealized drawing have been published in books and articles to illustrate a rutile sixling; e.g., see John White's posting in this thread showing this diagram from figure 40 in John Sinkankas' book "Mineralogy," (1964, p. 99).
