On A Piece Of Chalk is a scientific essay written by Thomas Henry Huxley, a prominent biologist and naturalist in the late 19th century. The essay was originally delivered as a lecture to the working men of Norwich in 1868 and later published in the Fortnightly Review in the same year. The essay explores the geological history of the chalk cliffs of England and the microscopic organisms that make up the chalk itself. Huxley uses this as a starting point to discuss the process of scientific investigation and the importance of observation and experimentation in understanding the natural world. Throughout the essay, Huxley draws upon his vast knowledge of biology, geology, and chemistry to explain the complex processes that have shaped the chalk cliffs over millions of years. He also discusses the role of science in society and the importance of scientific literacy for individuals and communities. On A Piece Of Chalk is considered a classic work of scientific literature and a testament to Huxley's skill as a writer and educator. It remains a valuable resource for anyone interested in the history of science, geology, or natural history.THIS 30 PAGE ARTICLE WAS EXTRACTED FROM THE BOOK: Selections of Huxley, by Thomas Henry Huxley.
