vas ERmrcutite? [p. 292]—In the year 1851 Mr, W. W. Jefferis found near the 
clinochlore locality at Westchester, hus pelea a peculiar wiih zy yellow mica-

resembling phlogopite, and it has for some years io en shenisiad among mineralo-

An examination of this substance made by Prof. J. Lawrence Smith and myself 
in 1853, showed its composition to be near that of chlorite, and it was considered by 
us to be a ween oe although our results were never published. My
