Add to basketHardcover. Condition: Very Good. 1st Edition. viii, 236 pp; 5 figs. Contemporary 3/4-cloth and marbled boards. Slightly foxed. Very Good. This copy does NOT have any library markings. First Edition. Garrison-Morton 698. Pfeffer "made the first direct measurements of osmotic pressures in plants. . ., which, published in his Osmot…ische Untersuchungen (1877), were to provide van't Hoff with the values for his calculations. Thus Pfeffer's work was invaluable in the development of the theory of solution, itself a landmark in the history of physical chemistry. . . . Using unglazed, porous porcelain cells, [Pfeffer] precipitated membranes of copper ferrocyanide within them. Tightly supported by the walls of the cells, they withstood increased pressures; and Pfeffer was able to make direct measurements of solutions of various substances at different concentrations and temperatures. Pfeffer considered this cell a model of the plant cell, or in his terms, the protoplast with its surrounding membranes. His results showed proportionate relationships between the concentrations of the solutions in the cells and osmotic pressures, and temperature likewise proved to be directly related to osmotic pressure. . . . Some time afterward, at Amsterdam, the botanist [Hugo] de Vries, who was engaged in researches related to osmotic pressures, met van't Hoff and told him of the values for osmotic pressures that Pfeffer had published in Osmotische Untersuchungen. Van't Hoff then referred to Pfeffer's work and drew his broad analogies between osmotic pressures and gas pressures. Thus Pfeffer's determinations were the values on which van't Hoff based his theoretical considerations. In his classic paper of 1887 van't Hoff outlined the experimental methods that Pfeffer had used in obtaining his determinations" (D.S B. 10: 576-77). "In his study of solutions, van't Hoff also investigated their properties in the presence of semipermeable barriers. He extended the quantitative investigation of the botanist Wilhelm Pfeffer (1877), who had contained solutions of cane sugar, and other substances, within membranes of hexacyanocopper II ferrate, which he formed in the pores of earthenware pots by soaking them first in a solution of copper sulfate and then of potassium ferrocyanide. Van't Hoff showed that the osmotic pressure P of a solution inside such a vessel immersed in the pure solvent is in apparently direct proportion to the concentration of the solute and in inverse proportion to the volume V of the solution at a given temperature. At a given concentration, P is proportional to the absolute temperature T. The relation serves the general gas law pV = kT" (D.S.B. 13: 579). Pfeffer's book was translated into English in 1985: Wilhelm Pfeffer: Osmotic Investigations. Studies on Cell Mechanics. Translated, with an Introduction, by G. R. Kepner & E. J. Stadelmann. New York: Van Nostrand Reinhold, 1985.
