Note.—Corundum occurs abundantly in the drifts of nearly all the

large bean. It has a conchoidal fracture, with (very rarely) indistinct 
crystal and cleavage planes. Specific gravity, 3:98; hardness, some- 
times over 9. An analysis, by Mr. J: Cosmo Newbery, of Specimen

380. GARNET CRYSTALS in 
QUARTZ. 
Bradford Lead, Maldon. 
These crystals are apparently not 
very rare in pebbles and crystals of 
smoky and transparent quartz in a cer- 
tain portion of the Bradford Lead. 
They vary in size from a small pins 
head to that of a small pea, and their 
general form is a combination of the 
leucitohedron with the rhombic dodeca- 
hedron.
