||P.117 note 'e' beneath Table 2: "RNAs concentration: stable RNA concentration. The cell volumes of E. coli and R. prowazekii were estimated as 1.1µm^-3 and 0.09µm^-3 respectiveiy (Austin and Winkler, 1988)." P.117 left column: "Accordingly, as shown in Table 2, R. prowazekii had 5.6 fg of stable RNA and 1500 ribosomes per cell, which is only
about 8% of the amount of stable RNA and ribosomes found in E. coli (71.2fg and 24 000 per cell). However, the cell volume of the rickettsiae is only about 8% of that of E. coli (0.09µm^3 vs 1.1µm^3, (Austin and Winkler, 1988))."
