H^MOLYSIS BY MEANS OF DIFFERENT QUANTITIES OF TETANOLYSIN 

 AT 37 C. 



The agglutinins display in their general behaviour a 

 very great similarity to the hsemolysins. This was de- 

 termined by experiments in which different quantities, q, 

 of an agglutinin (against Bacillus coli) were allowed to 

 act upon similar suspensions of this bacillus at 37 C. 

 Then the time necessary to produce a given degree of 

 agglutination was found to be inversely proportional to q 

 as will be seen from the following table.
