C.I.O.S. XXIII-14. Turbine Engine Activities at Ernst Heinkel Aktiengesellschaft. [Price 6s. 0d.] Reports on German Science Although not very large this is an extremely interesting report, since it traces the history of the Heinkel-Hirth engines during the ten years of their development. The types are illustrated by and Industry numerous sectioned drawings and half-tone illustrations, the latter being of limited value The following is a further selection of industrial reports of aeronautical interest that have so far been issued because of the very poor reproduction common to by the Combined Intelligence Objectives Sub-Committee and the British Intelligence Objectives Sub-Committee. these reports.
