MINERAL from GREENLAND. 395 
P) 
‘Mr Atxan fent a fpecimen of this mineral to Mr Exe- 
BERG, who analifed it in the courfe of laft fummer. The con- 
ftituents which he obtained, as he ftates them in a letter to Mr 
ALLAN, are as follows : 
Silica, ~ - ebay igGe 
Alumina, - - = ele gas 
; Soda, - - - Bigs 
Muriatic acid, = = 6.75 
Oxide of iron, - - 0.25 
100.00 
‘Tuts refult does not differ much from mine. The quantity 
of muriatic acid is much greater than mine. The lime and the 
volatile matter which I obtained, efcaped his notice altogether. 
If we were to add them to the alumina, it would make the two 
analyfes almoft the fame. No mineral has hitherto been found 
containing nearly fo much soda as this. Hence the reafon of 
the name by which I have diftinguithed it.
