2. MISCELLANEOUS ROCKS. 
A. Eleolite syenite, var. litchfieldite, from Litchfield. Nordmarkose. Described 
by Bayley in Bull. 150, p. 201; and in Bull. Geol. Soc. America, vol. 3, p. 231. Con- 
tains eleolite, two feldspars, and lepidomelane, with sodalite, cancrinite, and zircon 
as accessories. Analysis by L. G. Eakins, record No. 1298. P.R.C.77 and 949. 
B. Syenite porphyry, Appleton, Knox County. Prowersose. Described by E.S. 
Bastin in Jour. Geology, vol. 14, p. 173. Contains potash feldspar, albite, biotite, 
hornblende, zircon, titanite, apatite, iron ores, and a little quartz. Analysis by 
G. Steiger, record No. 2232. 
C. Pyrrhotitic peridotite, East Union. Lermondose. Described by Bastin in Jour. 
Geology, vol. 16, p. 124. Contains pyrrhotite, with some pyrite and chalcopyrite, 
olivine, plagioclase, hornblende, and magnetite. Also small amounts of biotite and 
spinel, with secondary serpentine, amphibole, chlorite, and calcite. Analysis by 
W. F. Hillebrand, record No. 2301. 
D, E. Two pegmatites (graphic-granite), Topsham. Collected by Bastin. Essen- 
tially quartz and orthoclase. Analyses by Steiger, records Nos. 2345, 2357. 
a For analyses of feldspar, elxolite, hydronephelite, lepidomelane, sodalite, and cancrinite from this rock,
