crystals of very irregular shape; the most prominent form is: 

 /•{lOTi}; ^(oiîl} is quite insignificant. As a rule no prism- 

 faces are developed. 



Turner Sund. At Turner Sund or its immediate neigh- 

 bourhood , various fragments of quartz were obtained , which 

 have no particular relation to one another. 

 II From the Sound itself, — no further particulars as to 

 locality being stated — , was obtained the in-filling of a 

 cavity, the outer part of which was formed of a thick layer 

 of calcedony, covered inside with quartz crystals. The cry- 

 stals were about b™'" in length and were of the ordinary 

 combination: ш {loTo}, г{1оГ1}, slolTl}; they were fairly 

 clear and transparent. 



2) Another specimen from Turner Sund consisted of a cavity, 

 quite filled with quartz, without any distinctly developed 

 crystals. 



3) On the mountain-slope by the Sound a larger cavity (ca. 2 

 dm.) was found. The walls of the cavity are Hned with 

 a thin layer of greenish calcedony and inside this are small 

 (1 — 2°™) transparent quartz-crystals. All the interior of the 

 cavity is filled with fibrous aragonite. The quartz crystals 

 are of a very characteristic form namely /'{юи} with very 

 well-developed bright faces; at the lower end each of these 

 is bordered by two symmetrically-situated faces, which re- 

 semble scalenohedral faces, but are of compound nature and 

 rough surface, so as not to produce the least reflection. 

 The prism and negative rhombohedron are not developed. 



4) From Turner Ö was obtained a smaller fragment, consisting 

 of a crust of calcedony and opal , on which groups of 

 minute quartz crystals of the ordinary from are developed. 



.51 On the mainland, from the north-west extremity of Turner 

 Sund, another specimen was obtained. This is a cavity 

 (ca. 12 cm. I lined with calcedony and filled in with (juartz, 

 having no distinct crystal form.
