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. The manuscript of Einstein 1910d (Vol. 3, Doc. 9) was sent under separate cover with the preceding document. Published as Einstein 1911a (Vol. 3, Doc. 12), which was received 30 November by the Annalen der Physik. The paper by Joseph John Thomson is Thomson, J J. 1910. 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. Friedrich Pockels and Paul Hertz. 228. From the Julius Springer Publishing House [Heidelberg,] 25. Okt. 1910 Herrn Professor Dr. Einstein, Zürich. Hochgeehrter Herr! Darf ich mir die Anfrage gestatten, ob Sie für die nächste Zeit irgend wel- che literarischen Pläne hegen, zu deren Ausführung ich mich Ihnen zur Ver- fügung stellen dürfte? Es wäre mir eine ganz besondere Freude, wenn Sie sich meiner Firma einmal als Verleger bedienen wollten. In vorzüglicher Hochachtung und mit besten Empfehlungen Ihr sehr erge- bener Ferdinand Springer TLSC (GyHeidS, Mappe Einstein E-24). [71 430]. Secretarial notes are omitted. The Teubner and Hirzel publishing houses had earlier expressed similar requests (see Docs. 59 and 126). Ferdinand Springer (1881-1965) was co-proprietor of the publishing firm, chiefly re- sponsible for natural-science publications.
