In this book, which is based on the study of 300 cases, Warren again brings into focus the various phases of the pathology of diabetes. A consideration of the insular hypothesis is followed by the description of the histology of the normal pancreas. The lesions of the pancreas seen in diabetes are then described and compared with lesions observed in the pancreas of nondiabetic individuals. A conclusion at this point is important.
