Natrolite. This occurs at Gates mountain, Cape d’Or, Two 
Islands, ete., often in bunches of transparent crystals. The fol- 
lowing analyses are by Prof. Marsh:

Scolecite, so called from its curling up like a worm before the 
blowpipe, also occurs with the rie tiaien Oa minerals. 
Mesolite is found in the North mountain of Kings Co., and 
Gates mountain with Farcelite, in masses up to the size of a 
man’s head, usually having the interior of fine pibrous radiated 
and somewhat plumose crystals.

1. Levynite growp.—Not represented here. 
3. Analcite growp.—Represented in Nova Scotia by the mine- 
ral of the same name. 
Analcite—So called from its weak electric power when heated. 
It is found at Martial’s Cove, Five Islands, Cape D’or, Swan’s 
Creek and McKenzie Head, as trapez ohedrons. It is generally 
presented in crystals in amygdaloid, sometimes an inch in diame- 
ter. A curious variety is described by Dr. Jackson, as occurring 
on the south shore of the Bay of Fundy. The crystals were 
verdigris green outside, and paler green within, from holding 2 
to 3 per cent. of carbonate of copper. It is sometimes found 
attached to plain cuts of copper holding it to the rock or sus- 
pending it in cavities.
