Abstract: 1. “Normal” agglutinins forB. typhosusandB. paratyphosusB appear to be conclusively of the O type. 2. Such agglutinins appear to be of consistently low titre and are absent in many sera. 3. Normal agglutinins forB. paratyphosusA have not been encountered. 4. O agglutinins are readily produced by inoculation of a T.A.B. vaccine, and may rise to as high titres as those encountered during an enteric infection. 5. It is impossible to fix any limit for residual O agglutinins in inoculated persons. 6. The value of examining for O agglutinins in enteric cases is confirmed. 7. Some fallacies of a purely qualitative method are pointed out, and a plea is made for the inclusion of the principles of qualitative receptor analysis in a quantitative Widal.
