1. Radiated Quartz. In the Southampton, Whately and 
Leverett veins of galena; in abundance. Also in Conway, 
in veins and loose masses. 
8. Tabular Quartz. In greenstone, Deerfield—Lamellae 
-usually applied to one another by their broader faces, and 
separating as thin as mica, but very brittle. Sometimes 
they intersect and produce cells of various forms. Also in 
Conway, in large loose masses among mica slate. Pieces 
more than a foot in diameter have been noticed, having both 
the structures above mentioned. The plates forming the 
cells are sometimes covered on their broader faces with mi- 
nute quartz crystals. In some specimens there is a gradation 
rom tabular to common amorphous quartz; the folia becom- 
ing less and less distinct, and finally disappearing. 
“9. Granular Quartz. At Vernon, Vermont, forming @ 
bed in argillite. (J. 4. Allen.) 
" cretion never much larger than a musket ball. But thezeo- 
lite, it is well known, does occur in radiated masses several
