by Winther, has only been found on one side of the cry- 

 stal, as has been shown by a later examination of the mate- 

 rial used. 



The schizolite as triclinic forms a very important link in 

 the wollastonite series the most important minerals of which 

 may be arranged in the following form. 



Without Na With Na 



Without Mn (monoclinic) wollastonite pectolite 



With Mn (triclinic) rhodonite schizolite 



The principal material of the present examination consists 

 of some small crystals in the sodalitesyenite- pegmatite from 

 Kangerdluarsuk collected by Flink in 1897, and on his 

 tables called «brown rhombohedra» , but not mentioned in the 

 above-cited account; they have the advantage of the other 

 varieties of the material that they are imbedded in a quite loose 

 material, and so whole crystals may rather easily be separated. 

 From the same locality we have a few excellent crystals col- 

 lected by Flink and by him termed «rhodonite-like mineral» ^). 

 Further I have, partly in later arrived material, also been able to 

 find rather good crystals of both the Winther- varieties of the 

 mineral; and finally, by searching older material collected by 

 K. J. V. S teen s trup in 1888, 1 have also found valuable pieces 

 with schizolite, especially one crystal from Siorarsuit on the 

 north side of the Tunugdliarfik- Fjord far surpassing all 

 the other crystals in size. 



It may even now be seen from the preceding that the 

 mineral occurs with very varying appearances , as well with 

 regard to crystalline form as to colour; gradual transitions are 

 however found between all the forms, and several of the most 

 important faces occur on all the crystals.
