About This Book

A series of controlled experiments compares mechanical and electrical responses elicited by varied stimuli in plant and animal tissues and in metals, using instruments such as myographs, electric recorders, and a block or vibration cell. Response curves are analyzed for period, amplitude, diphasic variation, fatigue, staircase effects, superposition, and hysteresis. The work examines how temperature, anesthetics, poisons, and chemical reagents alter responses, explores light-induced and retinal currents and visual analogues, and argues that molecular disturbances underlie similar measurable electrical phenomena in both living and non-living matter, treating electrical response as an index of physiological activity.

Transcriber’s note: Four likely printer errors have been corrected; these are on pages 46, 115, 176 and 186, marked like this. The inconsistent hyphenation of “break-down”, “electro-motive” and “vibration-head” is as in the original. Some of the illustrations had to be moved up or down a few paragraphs from their position in the original; the hyperlinked page numbers in the List of Illustrations point to the original locations, but the hyperlinked figure numbers point to where the figures are now.

PREFACE

I have in the present work put in a connected and a more complete form results, some of which have been published in the following Papers:

  • ‘De la Généralité des Phénomènes Moléculaires produits par l’Electricité sur la matière Inorganique et sur la matière Vivante.’ (Travaux du Congrès International de Physique. Paris, 1900.)
  • ‘On the Similarity of Effect of Electrical Stimulus on Inorganic and Living Substances.’ (Report, Bradford Meeting British Association, 1900.—Electrician.)
  • ‘Response of Inorganic Matter to Stimulus.’ (Friday Evening Discourse, Royal Institution, May 1901.)
  • ‘On Electric Response of Inorganic Substances. Preliminary Notice.’ (Royal Society, June 1901.)
  • ‘On Electric Response of Ordinary Plants under Mechanical Stimulus.’ (Journal Linnean Society, 1902.)
  • ‘Sur la Réponse Electrique dans les Métaux, les Tissus Animaux et Végétaux.’ (Société de Physique, Paris, 1902.)
  • ‘On the Electro-Motive Wave accompanying Mechanical Disturbance in Metals in contact with Electrolyte.’ (Proceedings Royal Society, vol. 70.)
  • ‘On the Strain Theory of Vision and of Photographic Action.’ (Journal Royal Photographic Society, vol. xxvi.)

These investigations were commenced in India, and I take this opportunity to express my grateful acknowledgments to the Managers of the Royal Institution, for the facilities offered me to complete them at the Davy-Faraday Laboratory.
