Abstract
THE first edition of this book was reviewed in Nature of July 18, 1942. According to the author's preface: “The appearance of a second edition of this book has been hastened by the extensive consumption of the first edition by the enemy Luftwaffe”. The opportunity has been taken to increase the size by some 15 per cent, by a general expansion of the existing chapters. New material has been added dealing with such subjects as frequency modulation, gas-filled valves, time bases, the Kipp relay, the transitron and the cathode follower; but the author has rightly resisted any inclination to go too far in meeting the general criticism of incompleteness. The book remains a very good survey of all the main types of valve circuits, presented in such a way that the student may be in a position to understand, or even foresee, further developments.
