Meddelelser om Grønland . Fig. 10. Schizolite. 127. Fia. 11. Schizolite. This principal type of the crystals is now altered in manyways by one or more of the faces getting predominance overthe others, the varia-tions, however, beingnot here so great asin the crystals fromNaujakasik, inwhich also several ofthe most rare facessnpervene, and whichare to be more par-ticularly mentionedbelow. Here I shallonly give a singleform (figure 11) hav-ing, besides the faces of the preceding one, also e{lll}, and being often found large crystal from Siorarsuit is isodiametric, andconsists essentially of the three pinacoids, but is ratherirregularly developed. The crystals from Naujakasik are the most varying andthe richest devel-oped of all. Theyare of the sameprincipal form asthose from Kan-g e r d 1 u a r s u ? ,but from thisform they de-velop very muchin all directions ;of the compara-tively few well-developed crystals I shall here give some in-stances each represented only by one or by a few individuals.
