Response in the Living and Non-Living

In this pioneering study the author draws together a series of experiments that show how both inorganic substances and living tissues react to electrical and mechanical stimuli. By recording minute voltage changes in metals, animal nerves and a variety of plants, he demonstrates striking similarities in the way matter—whether dead or alive—responds to a tap, a vibration or a sudden shock. The detailed illustrations bring the delicate needle‑and‑lever recordings to life, letting listeners picture the subtle currents that flash across a copper wire and a carrot root alike.

The work also explores how factors such as temperature, fatigue and the timing of repeated taps alter these responses, revealing that plants can exhibit “staircase” and additive effects much like muscles. Throughout, the narrative remains grounded in clear laboratory observations, offering a window into the early days of electrophysiology and the surprising continuity between the living and the non‑living world.
