Originally published in 1939, it was only recently that serious study and attention had been given to disorders of speech and there was a growing demand for books dealing with the subject. Abnormal Speech deals concisely with the aetiology of the varied abnormalities of speech and discusses the treatment practised by experienced therapists at the time, successful in affecting permanent cures. It was now recognised that the causes and classification of speech disorders were fairly numerous, and that the essence of treatment consisted of discovering the nature and cause to apply the appropriate method of treatment. It was revised in 1950 in some part to account for the effects of the second world war on speech disorders.Today it can be read in its historical context.This book is a re-issue originally published in 1939. The language used and views portrayed are a reflection of its era and no offence is meant by the Publishers to any reader by this re-publication.
