7. Explanatory Note concerning “ triclinic pyr oxene”; by 
Wuirman Cross.—In the Bulletin No. I of the U.S. Geological 
Survey, entitled: “On Hy ype ersthene-Andesite and on Triclinic 
Pyroxene in Augitic rocks,” which has recently been onaepes 
and of which an abstract appeared in this Journal for ruar 
Survey has oe kindly oslied my attention to the exhaustive in- 
vestigations of 
p- 349) upon the optical propert monoclinic pyroxene, in 
saiiati they ~ ow that the Eipsotd. of elasticity is so situated as 
to produce reat variations in optical behavior in sections 
which are bas ttle inclined to each other. This is especially the 
case for those sections which vary but a few degrees in fang 
from the one normal to the vertical crystallographic a 
eareful consideration of the matter in the light of the salsnlations 
of Fouqué and Levy, has convineed me that a great majority of 
the instances cited in the Bulletin as indicating a triclinic pyrox- 
ene, are explainable as augite, and that the few cases which still 
seem anomalous are not in themselves sufficient to justify a refer- 
ence to the triclinic system 
In explanation of this error it may be said that the work by 
Fouqué and Levy was not accessible to me at the time the article 
_ on “triclinic pyroxene” was written, for, although only recently 
published the paaper si de was completed and had been sent in for 
_ publication i befor 
regar > keypernchoce andes I may add that it has been 
recently found 4 in abundance among the voleanic rocks of Southern 
Colorado. Also, that the hypersthene has bee seg isolated from 
ee typical “augite? -andesites of ey viz: from Bagonya, 
Bath, and from the Tokajer Berg. The analyses of these hee 
sthenes, although not yet ready for ca bisaniont, show them to be 
and preclude the possibility of an admixture of 
eK, in the substance analyzed.
