specimens from another locality, to be mentioned hereafter, it is 
as difficult to discover a single crystal which has not the addition 
of secondary planes. 
The accompanying calcareous spar, like that similarly associ- 
ated from Brittany, is exceedingly phosphorescent, emitting a 
beautiful gold-yellow light when thrown upon a heated plate of 
iron. But this property is by no means peculiar to this substance 
thus associated ; for we have examined specimens from other parts 
of Nova Scotia, as well as from various localities in Europe and 
the United States, and find that all, without a single exception, 
possess this property, when placed on heated bodies. The 
Count de Bournon observed that from Brittany to be more phos- 
phorescent than any he had seen from other localities; and we 
are unable to say whether this from Nova Scotia is equal to that, 
not having a specimen from Brittany in our possession. 
About one mile east of Sandy Cove, the specular iron ore 
referred to, appears in more important veins, and affords speci- 
mens not inferior in beauty to those from Elba. When not 
massive, it occurs in flat, tabular crystals, often with curvilinear 
and striated faces, resembling many of the specimens of this 
substance from volcanic districts. Crystals, exhibiting some 
portion of the planes of the primary acute rhomboid, are some- 
times met with attached to the gangue ; but they are usually very 
much modified by replacements on their edges and_ angles, 
Magnetic iron ore also occurs at this locality, forming narrow 
veins in the amygdaloid; but neither of these ores occurs in 
quantities worth exploring. The best crystallized specimens of 
the latter, are found along the water-courses, in the soil that has 
been produced by the degradation of the amygdaloid that once 
surrounded them. Indeed, the soil is abundantly mixed with
