Excerpt from The Roentgen Diagnosis of Diseases of the Alimentary Canal We have purposely avoided extensive descriptions Of appara tus since this subject has been rather fully dealt with in several comprehensive publications. On the other hand, we have given detailed protocols Of the findings in a considerable number of cases which have come under our observation. Thus our hope is that the book will be Of some practical service to our co-workers in the field of roentgenology. For the sake of brevity, many citations Of authority have been omitted, but there is no pretense that the bulk of the facts related are from observations original with us. In the occasional instances in which we have dissented from the opinions Of others, we have endeavored to quote oppos ing views with fairness and without conscious implication that our own word should be considered final. Because of the lessons they may teach, our mistakes have been recorded unsparingly, but these errors should not be regarded as reflecting on the general efficiency Of roentgen diagnosis.
