1. Methods for preparing small amounts of Type I meningococcal polysaccharide which are electrophoretically homogeneous and contain only traces of other immunologically reactive material are given.
2. These polysaccharides are very poor antigens in man but in a small number of instances definite amounts of precipitin and protective antibody were formed.
3. The significance of these findings is discussed.
