The notes of the following case, observed by me a few years ago, have not, as yet, been published; I had hoped to have been in a position to confirm or correct my impressions of it by the study of another case of like nature, either in my own practice or in the literature of the subject. As I have not been able to do so, and as the appearances are of considerable interest, I am now sending the notes for publication, and I should naturally be extremely grateful to any reader who might be kind enough to give me information of any similar case.George D —, a man of fifty-six years, was referred to me for a radiological investigation of the stomach on June 28, 1931. He had a history, extending over several years, of recurrent attacks of epigastric pain, bearing no definite relationship to food and not relieved by vomiting. The pain had completely subsided about eight months previously, but about six weeks before this examination the symptoms had returned in an aggravated form, and the pain was now practically constant, accompanied by acid eructations and occasional vomiting. The general state was poor; there was some epigastric tenderness, but no palpable tumour, resistance, or rigidity.The examination was extremely difficult, from various causes, and it must be confessed that it was not possible to obtain a satisfactory radiogram.
