Abstract
Since 1907, when I did the first transfusion recorded in which tests for blood compatibility were made,<sup>1</sup>I have performed many thousand blood group tests. Occasionally I have had to correct my own errors as well as those of others. Experience with successive generations of hospital interns has taught me that, in spite of the simplicity of the test, most beginners will make mistakes in grouping unless specifically taught about certain sources of error. The subject is particularly important at present because: (1) Blood transfusion is being increasingly used; (2) the group test will probably be employed in the near future in medicolegal work, and (3) Buchanan's recent articles<sup>2</sup>denying the correctness of all the preceding work on the heredity of the blood groups make it necessary for some other person to do an extensive piece of investigation. <h3>WHAT IS THE BEST TECHNIC?</h3> A number of different methods
