14 (37), Thomson to Ledermann, 14 Aug 1937

Thomson refers to a proof or article which he had enclosed. This has not survived in the collection. He does not name the author, but suggests to Ledermann that he may want to contact him, either sending the letter by the fastest ship or communicating by cable, charging the costs to the Carnegie fund.

He refers to his British Journal of Psychology article discussed previously; highlighting that he wishes it to be understood by less mathematical readers, and encouraging Ledermann to follow it with a more mathematical one.
