Two corrections should be made in the item"Blood groups and disease" [Science 124, 674 (12Oct. 1956)] which reports a paper on associationsbetween blood groups and disease read to the British Association for the Advancement of Science.

The three diseases for which the evidence isoverwhelming are (i) duodenal ulcer, (ii) gastriculcer, (iii) cancer of the stomach. As is stated, theulcers are commoner in persons of group O, andcancer of the stomach in persons of group A.There is fairly strong evidence in connection withdiabetes mellitus and pernicious anemia; but theincidence is raised in group A, not groups O and B.

It should perhaps be added that practically allthe data so far come from Western Europe andNorth America, and the associations might be different or absent in other peoples.
