Archival note

This incomplete third set of corrected proofs was produced in April 1926 and bears fewer editing marks than Set II. The vast majority of the corrections that were suggested in Corrected Proofs Set II are incorporated in this typeset print which is arranged in the same 3 column layout. The same Adolf Holzhausen stamp with an adjustable date in the center is visible on the first page and includes a reference to the “K.u.K. Hof & Universitätsdruckerei” in Wien [Vienna]. The corrections indicated in this set of proof pages are incorporated into the final version which was published in the following months, suggesting that this was the last set of proof pages.
