DOWNLOAD EBOOKExcerpt from Report on the Diatoms of the Albatross Voyages in the Pacific Ocean, L888-1904 The coarse sand, Radiolaria, and like impurities are now removed by rotating the material in a glass evaporating dish. By quickly revolving the lowest point of the dish in a small circle of, say, one-half inch a peculiar motion is given to the contents, on account of which. The large sand and other coarse ingredients collect in a mound at the center, while the diatoms are held in suspension. The liquid is quickly poured off from the sand, the process being repeated until the sand is found under the microscope to be free from diatoms. The cleaned diatoms are then preserved in bottles in a 40 per cent solution of alcohol with distilled water.
