interesting mineral localities in Greenland, viz. the cryolite 

 deposit of lvigtut, and the sodalite-bearing eruptive rocks at 

 Julianehaab. 



The mineralogist who next visited Greenland was C. Pingel 

 (1828—29); his journey had a chiefly geological purpose, and 

 he visited oniy few and previously known mineral localities, 

 from which, however, he carried home valuable collections. 



Of great importance, also for the knowledge of the mine- 

 ral localities of Greenland, was H. Rink's famous scientific exa- 

 minations in this country. Rink lived in Greenland 1848 — 

 51 and 1853 — 56, partly for exclusively scientific purposes, 

 partly in the service of the administration. His mineralogical 

 collections were made with great skill; for the preparation of 

 the "Mineralogia groenlandica" they have been of similar im- 

 portance as those of Giesecke, together with which they are 

 kept in the museum of the university. Rink has given a pre- 

 liminary account of his mineralogical results in his comprehen- 

 sive works on Greenland 1 ). In these works he also gives lists 

 of all the minerals, until then known from Greenland; these 

 lists comprise about 70 species of minerals. 



About at the same time as Rink made his explorations 

 in Greenland, the knowledge of the mineral wealth of the 

 country was enlarged rather considerably by several private ex- 

 peditions , the purpose of which was to try to establish a 

 working of mines. Most of these expeditions started from 

 Copenhagen, and carried home to the museums many specimens 

 of scientific interest. J. H. Lundt searched for graphite at (Jma- 

 nak in 1850, and for copper, silver, and cryolite at Julianehaab, 

 Nunarsuit, and Arsuk in 1850, 1851—52, and 1859, and the 

 Englishman- J. W. Tayler worked out tin-ore and argentiferous 

 galena at lvigtut in 1854, None of these enterprises led to a 

 permanent working of mines, but in the last-mentioned year
