VWXYZZX 7%28%13%7%2%28% 9%6%MixedInagglutinableThe infrequence of inagglutinable strains is somewhat remarkable in view of the records of Indian observers. Thus Manifold and deMonte report 28.2% of 117 strains as inagglutinable. It is possible that the reason for this may be in the fact that in the latter group agglutination was carried out relatively soon after isolation, whereas in our series all strains isolated were subcultured weekly for three months before agglutination, thus permitting any agglutinable property to become manifest and fixed. The type sera used were those of Medical Research Council and all the strains recorded showed agglutination to 50% or over titre. Boyd's experience regarding saccharose fermentation has been confirmed by us, no agglutinable culture showing true saccharose fermentation. One of the inagglutinable cultures, however, showed definite acidity in saccharose. This strain has not yet been investigated thoroughly.
