||P.1819 left column 3rd paragraph: "The total energy consumption of Paramecium was estimated on the basis of the oxygen consumption. Fenchel and Finlay summarized the data of the total oxygen consumption rate measured
from the cells under various physiological conditions, such as
growing or starved cells at different temperatures (primary source). They obtained 0.19–4.4X10^–9 l O2h^–1 for a single cell (Paramecium caudatum). These values can be converted to the power, 0.38–8.8X10^–5J/hour/cell, by the conventional transformation of liters of O2 into 20.1 kJ (Schmidt-Nielsen, 1984)."
