This book provides an idealistic survey of adult education in Great Britain, written by several heads of university extramural departments. It covers the ideals, nature, activities, types of students, teaching methods, and qualities of extra-mural teachers. The book is valuable for both active adult educators and academic professors, highlighting the importance of pedagogic methods and ideals. However, it lacks critical analysis, which could have made it more valuable. The last third of the book includes useful appendices with official regulations, prospectuses, and references. This textbook, suitable for general degree students, is well-written and illustrated with diagrams and photographs. It covers a broad range of topics in botany and is recommended for British students despite its American character. The price is reasonable for a book of this size and content. This book briefly covers fundamental principles of thermodynamics and their applications in mechanical engineering. It includes topics such as gas and vapor properties, fluid flow, steam turbines, reciprocating engines, refrigeration, and combustion. The author has made many points clear and provided worked-out problems, making it a useful supplement for students. This book aims to bridge the gap between theory and practice in automatic telephony. It covers the rapid growth of automatic telephony and the problems solved to achieve progress. The second edition could benefit from incorporating statistical theorems to address 'holding time,' 'traffic flow,' and 'busy hour' issues. This book argues that logic is a human science, not just a collection of dry dogmas. It analyzes and explains the grounds of beliefs, the purpose of thinking, the importance of form, and the principles of deduction and induction. The book uses examples to make formal logic accessible and interesting.This book provides an idealistic survey of adult education in Great Britain, written by several heads of university extramural departments.
