of the saline which he employed for making the dilutions, and for

In the following experiments the leucocyte "separate" was 

 mixed, and equal volumes were distributed in various strengths 

 of saline, and centrifugalised. Equal volumes of a bacterial 

 suspension in distilled water were mixed with similar volumes of 

 saline of double strength. The serum was diluted with the 

 various salines. The period of incubation was 15 minutes.
