In this book, Saussure (1740-99) described his hygrometer, an instrument which measures humidity; described the general principles of hygrometry as a science; and dealt with evaporation and the application of his researches to meteorology. Cuvier regarded this book as one of the greatest contributions to science made in the eighteenth century.
