Abstract
When one is presented with a book having such a very broad title as ‘Introduction to Aeronautics’ one does not know exactly what to expect. But one looks for a broad treatment of the subject and not merely a treatise on one particular aspect. What one does find in this instance is an introductory treatise on some non‐structural aspects of the design of aeroplanes and rotating wing aircraft, together with some sketches of more fundamental matters. The precise contents can be judged from the titles of the eight chapters, which are: Basic Concepts; The Power Unit; Drag and Performance Estimation; Flaps, Take‐Off and Landing; Control and Stability; Wind‐Tunnel and Flight Testing; Flight Manoeuvres; Load and Pressure Distribution; Rotating Wing Aircraft. There is an appendix corresponding to each chapter. In his ‘Explanatory Note’ the author states ‘In the chapters the matters dealt with are treated only to the extent required for a practical application, the proofs of formulae being usually omitted. In the appendices selected matters are further expounded, and additional information and references to published Reports are given.’ And in the Preface he says, ‘I trust… that the contents and the method of presentation will be found acceptable by the aircraft technician and draughtsman, and by the student of aeronautics also’. These sentences explain very adequately the intention of the author and the scope of the book, while indicating its severe limitations.

AFTER‐CONFERENCE time is the period of reflection, and this year one involving several interests. There was uttered on the platform a warning that the question of the government control of public libraries was in the air; and Mr. Jast rigidly deprecated the discussion of the matter as a bye‐product of another subject then being debated. Library authorities and librarians, however, are asking for a lead from the Library Association, the only body competent or authorized to give it, and no doubt this will form the cardinal “policy” question of the winter.

Abstract
THE rocket motor is a form of jet propulsion which is characterized by independence of the external atmosphere for combustion, relative independence of altitude and flight velocity upon thrust, small frontal area for high thrusts, simple construction and low weight, and high rate of fuel consumption. Its use was greatly developed during the war years and many applications are now familiar to all. Most of the work on rocket missiles, such as the anti‐aircraft barrages, fighter armament, etc., was performed with solid fuel rockets, but liquid fuels were developed by the Germans for the well‐known V.2, for the Me. 163 aircraft, the Henschel glide bomb and various other applications. They concentrated a great deal of effort on this work and considerable technical progress had been made with different systems. Three main systems emerged and these were distinguished by the oxygen bearing fluids they used. The fluids were:
