Hitchcock first lists different types of fossils found in rocks, briefly mentioning how many fossils have been found of that type, and the location and type of rock where the fossil type is usually found. The types discussed include shells, insects, amphibians, and human fossils, among others. Hitchcock goes on to list several specific types of rocks and their composition, structure and varieties, including argillaceous schist, limestone, shale, and others. He ends the lecture with comments on geological theories in general, explaining in detail the Neptunian Theory and the Vulcanian Theory, both of which he then refutes. Hitchcock summarizes by nothing that while there is not yet an overarching accepted theory of geology, there are some facts agreed upon by geologists. Edward Hitchcock classroom lecture notes, "Shells" Edward Hitchcock classroom lecture notes, "Geology" Hitchcock, Edward, 1793-1864 Natural history lecture notes by Edward Hitchcock introducing the subject of geology to his students. Hitchcock discusses some of the difficulties involved in studying geology, such as less distinct differences between types of rocks, changes in rock structure due to heat, air, and water, and the challenge of examining rocks within the earth to confirm facts. He touches on several aspects of geology, especially the concept of strata, explaining the different types. Hitchcock lists several different types of rocks, such as granite, gneiss, slate, quartz, and red sandstone, and summarizes their composition, structures, varieties, and usual geological position. He additionally writes in-depth about different organic remains found within rocks, including different types of shells, plant matter, and animal remains. Edward Hitchcock classroom lecture notes, "Geology" Edward Hitchcock classroom lecture notes, "Notes To Lectures on Geology" Hitchcock, Edward, 1793-1864 Geology lecture notes by Edward Hitchcock on a wide variety of topics. Hitchcock focuses primarily on describing rock types (including where they are found and their varieties), the mineral composition of rocks, causes of geological change, several different theories of geology, and fossils. His discussion of fossils is broken down by type of organism, and includes descriptions of the organisms as well as information about the numbers and locations of fossils found.
