Each guinea pig of this series was inoculated subeutaneously with 2 cubic 

 centimeters of fresh antirinderpest serum. Six days later each animal was 

 reinoculated by massaging a shaved area over the abdomen with a portion of 

 a spleen from a guinea pig (No. 3058) just dead of plague infection.
