A classic of experimental science.
The first volume, first published in 1727 under the title Vegetable Staticks, was the "first complete account of the physiology of plants, including the reaction with air and movement of the sap" (Horblit). Hales measured the amount of water lost by trees and plants through evaporation and related this to the amount of water present in a given area of soil in which it was growing. He was the first to realize that trees and plants absorb carbon dioxide from the air and that it forms a vital part of their food supply. The separately published second volume, concerning the movement of blood in animals, was first published in 1733 (present here).
