This edition has been edited by Hugh Thursfield and Donald Paterson. Numerous changes have been made from the second edition, published in 1929. Archibald Garrod, one of the original editors, has again contributed to the chapter on metabolic disorders. Several entirely new chapters are included, such as those on blood transfusion, diseases of the new-born, rheumatism and tuberculosis. All the chapters have been revised. Numerous new illustrations have been included and newer therapeutic methods have been added. This continues to be the leading textbook on pediatrics by English authors.
