HITTORF, W. UEBER DIE ELEKTRICITÄTSLEITUNG DER GASE.
Leipzig: Johann Ambrosius Barth, 1869. Hardcover
Offered is the Very Good++ half-leather, marbled board bound entire volume 136 (Poggendorff's) Annalen der Physik und Chemie. Hittorf's paper is on pages 1-31 continued on 197-234 with two fold out plates in the rear. The current copy withdrawn from King's College Library with their stamps, bookplate front paste-down, small stamp verso of title page. No other markings. The text and plates are Fine. This report by Hittorf describes his investigations of the electrical discharge phenomena in a gas containing tube. His model, "The Hittorf Tube" led directly to William Crooke's work and the "Crooke's Tube", a glass tube with rarefied gas which was a critical step in the history of cathode ray tube design and development. Johann Wilhelm Hittorf (1824-1914) was a physicist who first computed the electricity carrying capacity of charged atoms and molecules. He formulated ion transport numbers and the first method for their measurements. He was instrumental in the discovery of cathode rays and, as reported in this paper, conducted valuable studies concerning electric phenomena in vacuum tubes.

In 1853 Hittorf reasoned Cations and anions exist in solutions and migrate under the influence of current through the solution. The migration of the cation toward the cathode and away from the anode, and the deposition of the anion on the positive electrode, together result in a decrease of the salt in the neighborhood of the anode. A similar analysis shows that there is also a decrease in the concentration of the salt in the neighborhood of the cathode. If the motion of the two dissimilar ions were the same, the decrease in the concentration of the salt would be the same at the two electrodes. Hittorf developed an experimental technique which allowed him to measure the changes in concentration at the two electrodes and found that they were not the same. He concluded that the speeds of migration of the cation and the Anion were different and he characterized this fact by defining "transport numbers," which specified the portion of the transport of electricity carried by each ion. (DSB Vol. 6, p. 439) Noted in DSB as one of Wiedemann's most important papers (DSB Vol. 14, p. 330).
