What reading level is The Geognosy of the Appalachians And the Origin of Crystalline Rocks An Addres book?
To quickly assess the difficulty of the text, read a short excerpt:
Just previous to this time, in the Report of the Regents of the University of New York for 1859, Professor Hall had described and figured by the name of Olenus, two species of trilobites from the slates of Georgia, Vermont, which Emmons had wrongly referred to the genus Paradoxides. They were at once recognized by Bar- rande, who called attention to their primordial character, and thus led to a knowledge of their true stratigraphical horizon, and to the detection of the singular error in Hising...er's book, already noticed, by which American geologists had been misled. * They have since been separated from Olenus, and by Professor Hall referred to a new and closely related genus, which he has named Olenellus, and which is now regarded as belonging to the horizon of the Pots- dam sandstone, to which we shall presently advert.
Farther studies of the fossiliferous rocks near Quebec showed the existence of a mass of sediments estimated at about 1200 feet, holding a numerous fauna, and corresponding to a great development of strata about the age of the Calciferous and Chazy formations, or more exactly to a formation occupying a position *For the correspondence on this matter between Barrande, Logan and Hall, see Amer.
