It was well worth while collecting these essays in book form; we only regret that they are not included in the 'International Psycho-Analytical Library' series. They are so familiar to readers of this JOURNAL as to call for no detailed description here. The book contains six essays by Professor Flügel entitled: The Psychology of Birth Control; Sexual and Social Sentiments; Some Problems of Jealousy; Maurice Bedel's 'Jerome': A Study of Contrasting Types; Esperanto and the International Language Movement; On the Character and Married Life of Henry VIII; together with two by Mrs. Flügel: 'On the Significance of Names', and 'Some Psychological Aspects of a Fox-Hunting Rite'. They all represent definite contributions to psycho-analytical knowledge, especially on its applied side. Written very fluently they gain an added interest from the great variety of themes dealt with. The book is a worthy contribution to English psycho-analytical literature.
