TABLE A. 



TABLE illustrating the manner of testing the activity of hsemolytic 

 amboceptor. 



Three to four times the minimum complete haemolytic dose of 

 hsemolytic serum is employed in the test, viz. in the above test where 

 a dilution of the amboceptor of 1 in 500 is the minimum quantity 

 showing complete haemolysis, a dilution of about 1 in 150 would be 

 used. 



TABLE B. 



TABLE illustrating the manner of testing the amount of complement 

 necessary to produce complete haemolysis in the presence of 

 varying amounts of amboceptor. 



(The number of + signs indicates the amount of haemolysis ; 

 + + + + = complete, 4- 4- + = nearly complete, + + partial, 

 + = trace.)
