Second edition, after the 1685 first. Boyle hypothezises thermodynamic principles and assumes heat to be the effect of tiny particles in "local motion", concepts that didn´t take hold until another hundred years. The part of the book titled "...Insalubrity and Salubrity of the Air..." is an attempt to explain the causes of the plague.
