I was gratified by the most favorable reception and wide usage received by the first edition of this book. A decade seems to be a short period for a book on pathology, and yet it witnessed many important changes of concepts, along with a formidable growth of knowledge. The second edition required extensive reorganization. There are new chapters on mitochondriopathies, on peroxisomal diseases and on spongy myelino pathies.

I was gratified by the most favorable reception and wide usage received by the first edition of this book. A decade seems to be a short period for a book on pathology, and yet it witnessed many important changes of concepts, along with a formidable growth of knowledge. The second edition required extensive reorganization. There are new chapters on mitochondriopathies, on peroxisomal diseases and on spongy myelino pathies. Major revisions and new additions were necessary in many chapters, for instance those on the dysplasias of the cerebral and of the cerebellar hemispheres, which were largely reorganized. The chapters on perinatal pathology were reordered and reorganized to give a more logical sequence of prenatal, perinatal and postnatal lesions. The entire text was worked over for brevity. A wealth of new references was added with the. aim of staying abreast with the literature up to summer 1988. All refer ences were double checked for errors. My gratitude goes to Mrs. Gisela Ropte and Mrs. Cynthia Bunker for their untiring, diligent help. As a result, this second edition is an essentially rewritten text. Advance in the prevention of human suffering is based on a thorough understand ing of the nature of disease. I hope that this text will continue to be of service in this behalf. Perhaps it may also reflect and foster the intellectual curiosity which makes the "reading of brains" so interesting an occupation. Gottingen, 1989 Reinhard L.
