nearly to be classed, are found in snow-white, marble-like, 

 fine-grained albite, and are formed as lengthened prisms gene- 

 rally united into stellate groups, often also densily interwoven 

 to a confused mass. The albite forms a quite compact and 

 coherent mass, almost completely without cavities, and I have 

 only in very few instances succeeded in getting the crystals 

 tolerably entire out of it. Besides the schizolite numerous 

 pseudomorphs of aegirine after arfvedsonite are also found 

 swimming in the albite , but on the other hand there is never 

 the slightest trace of unaltered arfvedsonite, and only in a few 

 parts original crystals of aegirine; further the rare minerals 

 epistolile and steenstrupite, the latter in well-developed crystals 

 that are here quite fresh , what is not the ease in any other 

 locality. In smaller numbers rather large individuals of micro- 

 cline-micropertite are found, sometimes also tables of zinnwal- 

 dite, and sometimes finally rather irregular crystals of sphale- 

 rite. The relation with regard to age between schizolite and 

 the other minerals in the albite is very varying, and seems not 

 to be subjected to any rule whatever. 



The schizolite from Kangerdluarsuk is also found in 

 grained albite, which has, however, a quite different appearance 

 here forming a quite loose aggregate (which may be pulverized 

 by being rubbed between the fingers) everywhere interwoven 

 with a very great number of small pointed needles of aegirine. 

 In this elementary matter the schizolite is found as quite small 

 (1 — б'"'^) brown crystals; they may be present in so great 

 numbers, that several hundreds of them might be gathered 

 from one kilogram. Among these fine-grained ingredients 

 some other minerals are found in large individuals, especially 

 microcline-micropertite, zinnwaldite, and aegirine ; characteristic 

 are also the frequently occurring masses of light green, fibrous 

 aegirine arranged in stellate groups. Further a great many 

 large crystals of steenstrupite are found here, always much 

 transformed and with very uneven faces. The crystals of
