Abstract
Since the discovery of normal human hemagglutinins by Ehrlich and the pointing out of their occurrence in groups by Landsteiner (1) with subsequent confirmation by Jansky (2), Moss (3) and many others, numerous workers have contributed to the more decisive identification of these groups. It has been shown by absorption as well as by specific agglutination (Hektoen (4), Koekert (5),) that four definite types of human blood can be identified.
Although iso-hemagglutinins are found in most species of lower animals it seems that no definite grouping exists. Ottenberg and Friedman (6) claim to have obtained definite typing in rabbits and steers.
Hektoen (7) studied the blood of not less than ten of each of the following species: rabbit, guinea pig, dog, horse and ox. He did not observe iso-hemagglutination in any of them.
Fishbein (8) studied 60 hogs, 60 cattle, 40 sheep, 25 rabbits, 10 dogs, and 20 frogs.
