This is a modified version of Barnes's letter of 1 March 1941 (record 121570), although the description of Patricia Russell's behaviour remains the same. He adds a paragraph praising BR profusely for his lecture of 2 March 1941.

Typed across the top is: "Copy sent to Mr. Cantrell." Rather than reply to this letter in writing, BR spoke to Barnes about it on 6 March. What he said was typed up as "Russell's reaction to the letter of March 3, 1941" (record 121578). BR did not show the letter to Patricia. BR said it was all "a misunderstanding". "These statements should have been sufficient to get Russell's attention that no special privileges could be claimed by his wife and that the first requisite of all persons coming to the Gallery is that they behave themselves properly."

Barnes remarks that BR's licence number (51AR5) is "very appropriate for a logician and mathematician".
