These have been collected from the official reports of six general hospitals in London, and extend over a period of ten years or more. Their chief value lies in the fact that they probably represent the best average of diagnosis that it is possible to obtain ; while the large number of cases dealt with in each instance, and the wide area from which they were drawn, help to reduce the margin of error to a comparatively small compass. The following table shows the results obtained from each hospital, and also affords a contrast with similar statistics, derived from two important institutions in the United States and one in Canada, which cover the same period of time.

A careful examination of these figures brings to light several interesting and important facts. In the first place, it will be observed that, in spite of the varying numbers of patients who were admitted into the different hospitals of London, the percentage frequency of carcinoma of the stomach as diagnosed in the wards is practically the same in every instance, and represents about 0.5 per cent, of all the medical admissions. Secondly, the proportional death-rate from the disease is also almost identical in each institution, namely, 1.4 per cent, of all the medical deaths. Thirdly, if the fatal cases in the medical wards are analysed according to age, it is found that for every 100 persons who died after the age of twenty years, 3T succumbed to carcinoma of the stomach. Finally, it is worthy of notice that the complaint was responsible for 13.1 per cent, of all the deaths which resulted from diseases of the digestive organs.1
