An empirical study of the mental and physiological effects of definite meteorological conditions. The seasonal and daily climatic changes that occur in the atmosphere are demonstrably linked to the human behaviour. In this book, meteorological records of conditions such as heat, wind, humidity, and barometric measurements are compared to records of behaviour extracted from schools, courts, police, banks, and even proverbs in traditional literature. The author advises that his findings are not the final conclusion on the matter, but should rather serve as a suggestion for further investigation. (Summary by Leon Harvey)
