IGNKUUS ANU Cnyo51ALLINE ROCKS. 15 
NEW HAMPSHIRE. 
‘A. Eleolite syenite, Red Hill, Moultonboro. Umptekose. Described by Bayley 
in Bull. Geol. Soc. America, vol. 3, p. 231. Contains eleolite, augite, hornblende, 
biotite, sodalite, albite, and orthoclase, with accessory apatite, sphene, magnetite, and 
an occasional zircon. Fibrous decomposition products are also present. P. R. C. 203. 
B. Mixed albite and orthoclase from A. 
C. Nepheline (eleolite) from A. Analysis by W. F. Hillebrand, record No. 1321. 
The mixed nepheline and feldspar were treated with dilute hydrochloric acid, and the 
residue was extracted with sodium carbonate solution. C represents the soluble part 
and B the insoluble. 
D. Camptonite, Campton Falls. Analysis by L. G. Eakins, record No. 1298. 
Described by J. P. Iddings in Bull. 150, p. 239. Contains hornblende, plagioclase, 
orthoclase, augite, iron ore, biotite, apatite, pyrite, and a mineral which appears to be 
analcite. Also variable calcite, serpentine, and chlorite. P. R. C. 92. 
E. Quartz porphyry, Pemigewasset. Toscanose. Analysis by Eakins, No. 1298.

1. ROCKS OF MOUNT ASCUTNEY. 
Described by R. A. Daly in Bull. 209. Analyses by W. F. Hillebrand, record Nos. 
1621, 1657. 
A. Biotite granite. LIparose. Contains quartz, orthoclase, plagioclase (micro- 
perthite), biotite, magnetite, sphene, apatite, and zircon. P. R. C. 1340. 
B. Basic segregation in biotite granite. Akerose. Contains biotite, hornblende, 
quartz, plagioclase, microperthite, much sphene and apatite, some magnetite and 
zircon. P. R. C. 1338. 
C. Another sample of B, but containing more hornblende. Akerose. P.R. C. 1339. 
D. Nordmarkite. Phlegrose. Contains orthoclase, plagioclase, quartz, hornblende, 
magnetite, apatite, and zircon, with very little biotite, titanite, diopside, and allanite. 
P. R. C. 1341. 
E. Basic segregation in nordmarkite. Akerose. Contains hornblende, augite, 
microperthite, orthoclase, plagioclase, quartz, magnetite, zircon, and apatite. P.R.C 
1342. 
F. Hornblende paisanite. Liparose. Dike. Contains orthoclase, quartz, horn- 
blende, magnetite, apatite, and zircon. P. R. ©. 1347.
