Thomson informs Ledermann that his article can be printed in Sociometrika or Psychometrika. He is unsure if the former exists and thinks it may be a typing error.

Thomson mentions that he has many letters and manuscripts of Ledermann still to acknowledge. These cover topics such as boundary conditions, and Ridley Thomson's criterion. Thomson lists the letters and manuscripts with brief comments.

He also discusses the progress of The Factorial Analysis of Human Ability, briefly outlining a possible structure and referring to work he has consulted including that of E B Wilson, Maxwell Garnett, and Irwin.

Thomson finishes the letter by telling Ledermann to have a good holiday.
