A set of animals, therefore, similar to the above were again submitted to the same treatment as the first, but as will be seen from Table IX no differentiation in the agglutinin titres was obtained the second time. This would suggest that the impaired agglutinin formation could not be ascribed to the consumption of the deficient diets. Another experiment about to be described gives further support to this view. 900 800- 700 600- 500- 400- 300 QOO. Table VIII. Agglutination.
