This separate is a hybrid of two publishing processes. It was circulated with GLNE endpapers, but the text is in a different style and format compared to the previous eight numbers in the series. A note on the title reads ‘This lecture was delivered to the West London Medico-Chirurgical Society as the Cavendish Lecture for 1912, and originally published in the West London Medical Journal, vol xvii, pp. 165–93, 1912’.
