In this small volume, Trevor H. Howell has condensed his long experience with clinical problems among older persons and the chronic sick into a readable, useful book. The chapters on Approach to Old Age, Geriatric Rehabilitation, Diseases in Old Age and The A.B.C. of Geriatrics are especially noteworthy for their discussion of the general problems of geriatric medicine. This is not an exhaustive, detailed textbook, but it nevertheless contains many interesting observations on diagnosis, treatment and rehabilitation in respect to diseases commonest among older patients. As the author well says, "Geriatrics is more a state of mind than a branch of medicine or a mode of treatment. It is a reaction against the belief that after sixty a patient is too old to be medically interesting or therapeutically rewarding." The reading of this book will be found rewarding by all physicians who see older patients.
