‎---- EDITION ORIGINALE de ce second écrit de SENEBIER sur la photosynthèse ---- BEL EXEMPLAIRE ---- "SENEBIER WAS THE FIRST TO OBSERVE THAT IN SUNLIGHT SUCH PLANTS ABSORB CARBONIC ACID GAS AND EMIT OXYGEN WHILE MANUFACTURING A SUBSTANCE WITH A CARBON BASE". (DSB XII pp. 308/309) ---- "Sénébier published several works dealing with photosynthesis. He showed that leaves in water, in the absence of light, do not allow the air they contain to escape, that the quantity of air produced is proportional to the light intensity (except during the first few hours), and that all the green parts of plants, not only the leaves, furnish air.... Sénébier proved by experiments with the nitric oxide eudiometer that the bubbles emitted under the influence of light consist of oxygen (dephlogisticated air) and he proved that the leaves perform their function also when they are isolated from the plant... Sénébier's experiments were repeated and confirmed by Ingen Housz...". (Partington III pp. 280/283)**4734/A2‎
