Abstract
IT is no easy matter to write a book on a subject like television which is making rapid progress. There is always the risk that when the work is on the eve of publication some new invention will render part of it antiquated. Something of this nature has occurred in this ease. Only a few days before writing the preface, the author attended a demonstration in New York given by U. A. Sanabria, a young experimenter from Chicago, who presented ‘close up’ pictures on a screen six feet square which were better than anything he had ever seen before. By special neon ares, special arrangements of holes in the discs and a special amplifier, Sanabria can produce pictures which show an almost complete absence of flicker and the detail of which is quite as good as that provided by the average home cinema. Seaming lines also are very little in evidence. We think it was wise to include in the preface what appears at first sight to be a technical afterthought. Anyone possessing some knowledge of electricity and radio can easily understand this book. We can recommend it to everyone who wants a general knowledge of the first principles of television given in an interesting and easily intelligible form.
