Memoranda, on a paper 'On the catalytic cyclization of aliphatic hydrocarbons. II' by E F G Herington and Eric Keightley Rideal Sectional Committee: Chemistry Alfred Charles Glyn Egerton saw the previous papers by the same authors, and reported favourably on the current paper, but thinks it should be withheld until after the war. Proposed to treat part II the same as part I, and print confidentially for limited circulation. Can the paper be passed? Walter Norman Haworth agrees to pass the paper.
