The book is a collection of his scientific research on nitrous oxide or dephlogisticated nitrous air and its respiration. Davy was a chemist and inventor who is best known for his work on the discovery of several elements, including sodium, potassium, and calcium. In this book, Davy presents his experiments and observations on the properties of nitrous oxide, including its effects on the human body when inhaled. He also discusses the chemical reactions that occur when nitrous oxide is exposed to various substances and the implications of these reactions for the understanding of chemical processes. The book is written in a clear and concise style, making it accessible to both scientific experts and lay readers interested in the topic. It is considered an important work in the history of chemistry and has been influential in the development of modern anesthesia and the study of gas chemistry.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
