xv., p. 362-372. "In approaching the primitive masses of Mont Rosa, and the
mountains situated to the west of Coni, we perceive that the secondary
strata gradually lose the characters inherent in their mode of deposition.
Frequently assuming a character apparently arising from a perfectly distinct
cause, but not losing their stratification, they somewhat resemble in their
physical structure a brand of half-consumed wood, in which we can follow the
traces of the ligneous fibers beyond the spots which continue to present the
natural characters of wood." (See, also, the 'Annales des Sciences
Naturelles', t. xiv., p. 118-122, and von Dechen, 'Geognosie', s. 553.)
Among the most striking proofs of the transformation of rocks by Plutonic
action, we must place the belemites in the schists of Nuffenen (in the
Alpine valley of Eginen and in the Gries-glaciers), and the belemnites found
by M. Charpentier in the so-called primitive limestone on the western
descent of the Col de la Seigne, between the Enclove de Monjovet and the
'chalet' of La Lanchette, and which he showed to me at Bex in the autumn of
1822 ('Annales de Chimie', t. xxiii., p. 262).
