A Treatise on Meteorological Instruments
 Explanatory of Their Scientific Principles, Method of Construction, and Practical Utility

by Enrico Angelo Lodovico Negretti

"A Treatise on Meteorological Instruments" by Negretti and Zambra is a scientific publication written in the mid-19th century. This work serves as a detailed guide on meteorological instruments, emphasizing their scientific principles, construction methods, and practical applications. It aims to educate readers, ranging from general public audiences to more specialized users, on a variety of devices essential for understanding and measuring weather and atmospheric conditions. The opening of the treatise provides an introduction to the relevance of meteorology in predicting storms and tracking weather patterns, highlighting the need for a deeper knowledge of the instruments used in the field. The authors present a comprehensive overview of barometers—one of the primary instruments in meteorology—explaining their historical inception, various types, and the corrections needed for accurate readings. This sets the stage for the book's forthcoming detailed explorations of different meteorological instruments used for measuring pressure, temperature, humidity, rainfall, and more, laying a foundational understanding for the reader.
