| Abstract: | The specific polysaccharide of Type III pneumococcus, with only 0.05 per cent of N and 0.01 per cent of P, still shows almost maximal precipitation of a Type III antipneumococcus rabbit serum and the expected antigenicity in man. There is therefore no evidence that a prosthetic group is involved in these characteristic activities. |
