Z. exp. Path.Therap., 6. - Berlin, August Hirschwald, 1909, 8°, VI, 916, (2) pp., 7 Taf., Halbleinenband der Zeit. First Edition. This early work on the quantitative measurement of blood hemoglobin describes the method of determining concentration and includes text figures of the instruments as well as two folding data tables. "In 1906, Johann Plesch (1878-1957) of Budapest, working in Berlin, described a selenium cell-galvanometer for measuring hemoglobin based on the principle that the color of the solution was inversely proportional to its concentration. In due course, increasingly sophisticated colorimeters, comparators, photometers, and spectrophotometers were developed to measure color intensity and light absorbance" Bud and Warner, Instruments of Science, p. 310 "A simpler method of obtaining mixed venous values, by rebreathing gas mixtures out of small bag until the blood coming into the lung was in equilibrium with the lung-bag system, was discussed in part of an extensive and now all but forgotten monograph, "Hämodynamische Studien," by J. Plesch in 1909. His method was used on a series of normal and abnormal subjects. In the two decades that followed there were modifications of the procedure and further attempts to measure cardiac output by this indirect Fick procedure." Alfred P. Fishmann & Dickinson W.Richards: Circulation of the Blood. Men and Ideas (1964), pp.99,124.
