2. P.Tebt. I (1902).
5. The review, on pp. 75-76, is unsigned, but its authorship is clear enough from the content; i.e., Grenfell and Hunt need not have been informed about it (though they certainly could have been).
7. A period would be expected here, but the hole punch would have removed it.
8. Edward Hicks became the bishop of Lincoln in 1910; he was also an epigrapher.
10. Later addition, which annotated once more later in the letter, probably done by Wheeler or a delegate. Possibly a reference to Frank Stevens, who served in the president's office. For more on Stevens, see here.
12. Friedrich Blass, a close associate of Grenfell and Hunt.
13. Another later addition, which is replicated four more times throughout the letter, though it is unclear what it refers to.
14. Now known as Accademia Nazionale dei Lincei.
17. Brackets around page numbers and cross-out in pencil likely also added by Wheeler or a delegate.
28. Another later addition in pencil. The review appeared in vol. 17 (1904), fasc. 73-74 (Jan.-Apr.), pp. 129-31. Grenfell must have been alerted that it was coming.
29. No review of P.Tebt. I seems to have appeared in Neue Philologische Rundschau.
30. Potentially Ludwig's home address – the buildings seem residential.
31. Henry Frowde was the manager of the Oxford University Press.
