258 DOCUMENT 228 OCTOBER 1910 An entry in his "Scratch Notebook" (Vol. 3, Appendix A), [p. 30], indicates that he not only had an appointment at the Ministry, but also with Ernst Mach and with Anton Lampa (see Wolters 1987, pp. 130-133). An evening spent with Friedrich Adler's father Victor on this oc- casion is described many years later (see draft on verso of Emma Adler to Einstein, 9 July 1930), though Einstein gives an incorrect year. [2]The manuscript of Einstein 1910d (Vol. 3, Doc. 9) was sent under separate cover with the preceding document. [3]Published as Einstein 1911a (Vol. 3, Doc. 12), which was received 30 November by the Annalen der Physik. [4]The paper by Joseph John Thomson is Thomson, J J. 1910. [5]Winter semester 1910/1911 at the University of Zurich began 17 October (see Zürich Ver- zeichnis 1910b, title page) Einstein lectured on electricity and magnetism (four hours a week to sixteen students and six auditors) and on selected chapters in theoretical physics (two hours a week to eight students and two auditors), as well as conducting a physics seminar (one hour a week for five students and one auditor) and directing a laboratory every day for more advan- ced students together with Professor Alfred Kleiner (see Kontrollbücher über die Honorarge- bühren, W.S. 1910/11, SzZU, Kassa-Archiv, and Zürich Verzeichnis 1910b, p. 22). The lecture notes on electricity and magnetism are presented as Vol. 3, Doc. 11. [6]Friedrich Pockels and Paul Hertz. 228. From the Julius Springer Publishing House [Heidelberg,] 25.

In vorzüglicher Hochachtung und mit besten Empfehlungen Ihr sehr erge- bener Ferdinand Springer[2] TLSC (GyHeidS, Mappe Einstein E-24). [71 430]. Secretarial notes are omitted. [1]The Teubner and Hirzel publishing houses had earlier expressed similar requests (see Docs. 59 and 126).
