Edward Hitchcock classroom lecture notes, "Geology"
Description:
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.
