both agglutinins, but anti-E is also inhibited by D-glucose. Other 

 sugars of group 4 do not seem to inhibit anti-C ; therefore I have no 

 confidence yet that the terminal unit is a stigar of this group (Table 

 7-9). It seems possible that a sugar of group 3 is the terminal unit

of the E receptor, considering the effectiveness of sugars of this group 

 in inhibiting anti-E (Table 7-10). The inhibition by L-allose, a 

 group 2 sugar, is unexpected and is not paralleled by inhibition by 

 other group sugars. 



If it should prove that the D receptor, and possibly the C and E
