On agglutination of normal human blood.

It is appropriate to dedicate the first issue of TRANSFUSION to the man who laid the foundations for this field of science. 1961 is the diamond jubilee of the publication of the description of “the so-called Landsteiner reaction” in the Wiener Klinische Wochenschrift (14: 1132, 1901). T h e translation which follows was prepared through the courtesy of Professor A. I,. Kappus, Chairman of the Department of Microbiology at the Marquette University School of Medicine. Dr. Kappus made every eflort to preserve the flavor of the original article which was made difficult by the involved construction of the academic German in use at the turn of the century. Those who are interested may determine Dr. Landsteiner’s blood group by studying his tables. This observation serves to underline the importance of the procedure of “proving the blood groups” by the method introduced by Karl Landsteiner.
