 cases, and of these 20 negative cases 11 gave positive comple- 

 ment fixation tests. In addition to these 20 cases, there were 

 9 cases in which a streptococcus was seen in the Gram stain of 

 the stool but could not be obtained in culture for identification, 

 and of these, 7 gave positive complement fixation tests with 

 Streptococcus viridans antigen.
