in human blood typing, namely, the saline ag- 
glutination, the antiglobulin, the enzyme-treated 
red cell, and the enzyme-treated red cell anti- 
globulin method, as well as inhibition tests for 
A-B-H and Lewis substances in saliva. All anti- 
sera have to undergo careful absorptions to 
prevent false positive reactions due to non- 
specific antibodies present in the majority of the 
sera. 
The information accumulated through our 
work during the last decade has resulted, among 
others, in the increased use of primate animals 
in experimental surgery requiring blood trans- 
fusion and priming of the heart-lung machine. 
All the chimpanzees and baboons used as organ 
donors for human patients throughout the world 
since 1964, as well as most of the primate ani- 
mals used in cross-circulation of patients in 
hepatic failure, have been tested in our labora- 
tory.
