At Eqe, on the western border of the Greenland Ice Cap, measurements of the crystals by Seligman's method give a mean crystal diameter of 2.16 cm. at a place where the ice velocity is ceto m.fday. The "heterometry index" measured from granulometric curves by Cailleux's method shows that melting, active ice crystals have reasonably homogeneous dimensions, with a mean diameter from 2 to 2.4 cm.
