First sentence: Although the neighborhood of Philadelphia was explored by amateur mineralogists as early as 1820, and those large and beautiful private cabinets of minerals began then to be collected which afford rich materials for Dr. Genth's Report on the Mineralogy of Pennsylvania, to be published, this winter, as part of the first fruits of the Second Geological Survey of the State, it was not until about the year 1830 that intelligent eyes were cast upon vegetable and animal fossils, and curious minds undertook the problems of structural geology.
