From an analysis of reports from hospitals in Great Britain Nicol (1941) suggested that there is a geographical variation in the relative frequency of gastric and duodenal ulcer. Doubtless other geographical variations would come to light if sufficient information were available. Unfortunately the majority of hospital reports deal exclusively with in patients, and if the criteria for admission vary from one hospital to another the omission of out-patients may lead to serious error. So far the only complete survey of hos pital patients with peptic ulcer in this country was made in the Greater London area (Avery Jones and Pollak, 1945). We present for comparison the experience of a hospital in the West of Scotland.
