[The impedance diagram of the nitella]

From olden time the resistance and capacitance of the living body were measured by alternating current bridge and the impedance diagram was made by rend 1/omega c using orthogoual axises, and it showes an arch. But by this research the impedance diagram of the Nitella was a line those are measured by finite alternating current. Formerly the frequencies were from 0.2Kc to 20Kc, but by this research the capacitance are nothing at over 4Kc.
