Albin Matson Department of Bacteriology, University of Utah Medical School, Salt Lake City, Utah Introduction It is almost axiomatic to state that no two living things are exactly alike. From time immemorial, morphological differences in animals and plants have been recognized as a basis of differ entiation between species. Not only do we recognize differences between species, but within species there exist morphological differences of lesser degree. Thus, human individuals are recognized by such distin guishing characteristics as size, shape, features, color of skin, eyes, hair, etc. Even voices differ; and the fact that finger prints of one individual are different from those of any other is accepted as evidence in our courts. .... Moreover, less apparent differences in the blood are per ceived by serological means. This was made possible by the work of such immortals as Gruber and Durham," Kraus," Pfeiffer," Bordet.! and Nuttall" whose ingenious hands in the last decade of the past century developed the serological techniques of agglu tination, precipitation and specific hemolysis and established the specifity of these tests. .... Discovery of the Blood Groups - The finding of these serological species differences in plants and animals raised the question as to whether specific differences existed in the blood between individuals of the same species and, if so, whether they could be similarly demonstrated. This quest ion. was attacked by Ehrlich and Morqanroth," who, by immuniz ing goats with blood from other individuals of the same species were able to demonstrate by specific hemolysis individual dif ferences between goats. .... .... Only a few months before Ehrlich and Morqanroth" published the results of these experiments, the first statement of Land steiner," 8 concerning the appearance of isoagglutinins in human blood appeared. His method was the simplest possible, namely, the mixing of the serum of one individual with the red blood cells of other normal persons. By such procedure, he was able to demon; strate and to correctly interpret the intra species clumping of red blood cells. It was not a pathological reaction, nor 'yet a ran .... .... ....
