The EDITORS regret that in the review of Sigmund Freud—Arnold Zweig Briefwechsel, which appeared in This QUARTERLY, XXXVIII, 1969, pp. 643-644, a number of factual errors escaped detection. Accordingly, we want to point out the following:

• 1Arnold Zweig and Stefan Zweig were not brothers.

• 2Jacob Burckhardt was a contemporary of Nietzsche, not of Freud.

• 3Siegfried Jacobsohn, editor of Die Weltbühne in Berlin, did not study with Freud.
