Results obtained by dilution series are sometimes so unlikely that doubt is cast on the validity of the method. Criteria for the rejection of results are discussed and a Table is given of acceptable results for tests with five tubes for each of three tenfold dilutions. Methods of estimating the concentration of bacteria for other numbers of tubes or of dilutions are suggested. The inherent lack of precision of the dilution series method is stressed.
