A short Summary of Contents. 625 



the reader is referred to the literature quoted. When new 

 crystal faces have been described, the fundamental angles given 

 by Dana have also been used by their calculation. 



After this part of the work follows pp. 589 — 600 a geo- 

 graphically arranged list of all the Greenland mineral 

 localities; the arrangement is the one stated above. The 

 names of localities, where nothing more particular is stated, 

 may be found on the attached map; with regard to the others 

 their approximate situation may easily be found by means of 

 the informations given below 1 ). 



As in the greater part of the mineralogicai literature an 

 older spelling of the Greenland names is found, differing con- 

 siderably from the one used in this work, the alphabetical 

 index of the localities is followed by another (pp. 610 

 seq.) giving the earlier names of these localities. By 

 this means any doubt as to the identification of the loca- 

 lities will almost always be precluded; where the choice is to 

 be made between several localities with the same or almost 

 the same name, it must be decided in each single case, which 

 of them is the one intended, by an examination of the minerals 

 found at each individual locality. 



In conclusion 1 have to offer my best thanks to Dr. phil. 

 K.J. V. Steenstrdp for the assistance he, by means of his extended 

 knowledge of the minerals of Greenland, in every way has lent 

 to me during my preparation of this work.
