The sparkling middle figure is known by the common 

 name of glimmer, or scaly iron ore, and often accompanies 

 the above, as well as the black and red haematites. It is 

 blackish or red occasionally. The little bright faces of the 

 scales reflect the light with great brilliancy, particularly by 

 candle light, as the figures will show with the utmost ni- 

 cety, as the very substance was of necessity used for its 

 own representative. The liggest figure is among broken 

 quartz or rock, covering the surface or filling little hollows 

 in a scattered manner. The lower figures are aggregated 

 bundles, which are often found much larger: they have some- 

 times a tendency to crystallize in small rhombs, but I have 

 not yet seen them large or distinct enough to be measured. 

 The angles appear to be the same as in the foliated part 

 above, to which the lower evidently belongs. It is found 

 in Devonshire, whence we received it by favour of Colonel 

 Montague and the Rev. A. Neck. The same was also 

 sent from Scotland by Mr. Winch. The upper one was 

 received from Wales, by favour of the Rev. Mr. Williams,
