Preliminary experiments on the high frequency 100 and 250 megacycles internal conductance of Escherichia coli are reported. Observations indicate a difference in conductivity at the two frequencies, which is presumed to be a property of the macromolecules composing the cells. The effect of washing on internal conductivity was investigated by a single set of experiments that indicated definite loss of internal conducting material with washing, the percentage loss per wash decreasing after the third wash, and surprising behavior after seven to nine washes, indicating either a change in cell permeability or osmotic response.
