5. Phillipsite Group. 
This group as represented by Phillipsite is reported to have 
been found in this Province, but I have not seen any specimens 
myself. It is well known as showing beautiful cruciform crys- 
tals, of three twinned prisms crossing each other at right angles. 
6th. Iam not aware of the occurrence of members of the 6th 
or Harmotome, or of the 7th, or Stypostilbite, groups among our 
Nova Scotia varieties. 
Sth. Stilbite group. 
Stilbite—This is the most common of our trap minerals. Its 
colours usually white and lustrous, whence its name, and it is 
presented in sheaf-like, lamellar and radiated forms. At Part- 
ridge Island it occurs as a perpendicular vein from three to five 
inches wide and 50 feet long, intersecting amygdaloid. Also 
found at Isle Haute, Gulliver’s Hole, Digby Neck, Black Rock; 
Hall’s Harbor, Blomidon, ete. 
Epistilbite. —This variety occurs in small reddish crystals, 
nearly or quite opaque, at Margaretville, associated with stilbite.

Heulanaite—This mineral occurs at Peter’s Point in white 
and reddish colours, with Laumontite, Apophyllite and Thompson- 
jte, also at Blomidon and Black Rock in crystals, colourless and 
flesh-coloured, frequently an inch and a half long, and at Two 
Islands as yellow crystals, and at the localities rmteded under 
the head of Stilbite. 
Cerinite is of a similar composition, but massive with waxy
