| Première édition, exemplaire sans les planches. "Un ouvrage qui fait époque dans la science botanique" (Plesch), par le philosophe et naturaliste genevois Bonnet. "Bonnet is considered one of the fathers of modern biology. He is distinguised for both his experimental research and his philosophy, which exerted a profound influence upon the naturalists of the 18th and 19th centuries. In the ÇRecherchesÉ, Bonnet grouped five memoirs all of which where of prime importance for plant biology: He precisely described the characteristics of the nutrition of leaves and of their transpiratory phenomena. Although he did not know the kinds of gases (oxygen and carbon dioxide) produced and absorbed by green leaves exposed to light, Bonnet made very careful observations on their production. For his masterly experimentation, Bonnet should be considered one of the first naturalists to investigate experimentally the question of photosynthesis. He studied the movement of leaves and discovered the epinastic phenomena; he observed the position of leaves on the axis of the stalk and collected a great many anatomic facts; he returned to experiments on etiolation, on the movement of the sap, and on teratology."
