Agglutination of the cysts of E. histolytica obtained from culture occurs in dilutions of the blood serum of man and of the horse. Judging from the few cases studied, there appears to be no correlation of this agglutination phenomenon with either infection with E. histolytica or complement fixing properties of a serum. Further investigation of the problem seems indicated.
