126 On the Chemical Composition of Wernerite, 
formula, that, together with the results of Stromeyer and 
Wolff, there can no longer be any doubt as to the composi- 
tion of meionite. 
Epidote has likewise an oxygen ratio = 1:2:3,; conse- 
quently it and meionite are heteromorphous substances, a 
circumstance which will require notice subsequently in 
speaking of the occurrence of epidote pseudomorphous of 
meionite. 
II. ScAPOLITE (Ro),, 2 SiO, + 2 (R, O, Si O,). 
Oxygen ratio in Ro, R,O,, S10, = 1:2: 4. 
1. Blue Scapolite from Malsjo ( Wermeland ).—Density 
2°763. Occurs together with blackish green mica and green 
salite. Hydrochloric acid effects only a partial decomposi- 
tion of this as well as all other scapolites. Analysis gave :—

2. White Scapolite from Malsjo.—Density 2°658 ; occurs 
accompanied by salite and green hornblende in granular lime- _. 
stone. 
The high per-centage of water, as well as the presence of 
carbonate of lime, imperceptible by the naked eye, are pro- 
bably indicative of incipient decomposition. Analysis gave :—
