“Scientific Design of Exhaust and Intake Systems,” by Philip H. Smith, C.ENG., M.I.MECH.E., M.S.A.E., has gone into a revised edition (quite thick, with 246 pp.), which includes a new chapter on exhaust purification although inevitably the book is not entirely up to date, the latest Ford cross-flow head not being included. It covers very thoroughly the theory and practice of flowed inlet and exhaust systems, valve timing, pressure phenomena and pressure measuring apparatus, silencer design, racing methods with manifolding and multi carburetters, etc. The publishers are G. T. Foulis & Co. Ltd., 1-5, Portpool Lane, London, and the book costs 42s.
