Miscellaneous Localities of Minerats. 228 
2g. Brown Hematite, in mammillary concretions, surface 
-clove-brown and velvet-black, of a beautiful iridescent lustre ; 
on the serpentine ridge. 
29. Chalcedony, coating drusy quartz, and in botryoidal 
and mammillary masses, of several colours; on the serpentine 
ridge. 
$0. Jasper, of various colours, in cellular quartz; on the 
serpentine ridge. 
31. Black Tourmaline, in large cylindrical crystals, termi- 
nated by three sided pyramids, truncated on the edges. Same 
locality. 
32. Mica, crystallized in hexaedral flat prisms, or tables ; 
on the serpentine ridge. 
33. Drusy Quartz, of beautiful varieties, colour yellow and 
white ; abundant en the serpentine ridge. 
34. Ligniform Asbestus. Same locality. 
35. Fine Amianthus, forming veins in the serpentine. 
Same locality. 
36. Fibrous Talc, in ligniform masses, of a white and green- 
ish colour; on the serpentine ridge. 
37. Fluate of Lime, amorphous; in Edwards’s lime 
quarry. 
38. Sulphuret of Iron, in large cubic crystals, truncated on 
all the edges, one and a half miles north-west of Unionville. 
39. Brown Spar, in curved laminated masses. Same lo- 
cality. 
40. Red Garnets, in beautiful dodecaedral crystals, in mica 
slate abundant. Same locality. 
East Marlborough Township. 
Al, Zircon, in beautiful tetraedral prisms, terminated by 
pyramids, with additional faces on their angles, of a brownish 
red colour; occurring, detached, in the gravel and sand, on 
the sides of the mill race of David Pusey, 2 of a mile south of 
Marlborough-street road. We believe its matrix has been 
gneiss, which is now decomposed and disintegrated, as seve- 
val crystals were found imbedded in friable and decomposed 
gneiss. 
42. Red oxyde of Titanium and Egeran, finely crystallized 
detached. Same locality with the zircon. 
43. Scapelite,. in regular tetraedral prisms, (primitive 
form,) in a lime quarry, near the zircon locality.
