Six microscopic enlargements of minerals, page, photomechanical print, Image 1 is gypsum crystal, 2 is cesium crystal, 3 is magnesium phosphate crystal, 4 is magnesium phosphate crystal, 5 is ammonia crystal and 6 is zirconium crystal., number: 'Tafel XIII', number: '1, 6', photographer: Emil Cohen, Greifswald, cliché maker: J. Grimm, Offenburg, c. 1880 - in or before 1885, Baden-Württemberg, Mecklenburg-Vorpommern, paper, collotype, photoprint, height 233 mm x width 149 mm, minerals and metals, A vertical page with six circular grayscale microscopic images arranged in two columns and three rows, each circle showing different particle or crystal patterns; the top left circle contains needlelike radial clusters and straight elongated rods, the top right shows scattered irregular rounded clusters and small specks, the middle left has dense angular shardlike fragments clustered throughout, the middle right displays larger geometric crystal shapes with some rectangular and crosslike pieces on a smooth background, the bottom left features many small irregular dark grains dispersed across the field, and the bottom right shows scattered small rounded and irregular dark spots with a few larger clustered areas; the circles are set against a light background with margins visible around the page.
