I think that would be Triodes. The equations (at the beginning of Books I, II and III) are still there in the 2015 collected. I don't remember if they were included in the previous collected volumes.

Does anyone know which book or booklet it was by JH Prynne which appeared, some time ago, with a mathematical equation or formula prefacing the text?    And confirm that it was removed from reprintings in any of the collected volumes?
