The growth of individual organisms of four Gram-negative species has been measured. The growth rate of the individual was not in general constant, and its mean value differed from one organism to another in the same culture. There was positive correlation between the size of an organism at termination and the size of its mother at termination. These findings are contrary to the major postulates of the Koch & Schaechter hypothesis, but are so far no more than qualitatively established. Fission is unsymmetrical in respect of growth rate and size; the growth rate and size of sisters differ systematically according to their relative positions in the family tree.
