On Approach caused by Velocity and Resulting in Vibration

Abstract

PROF. J. CLERK-MAXWELL, in his recent paper on “Action at a Distance,” has brought under notice again the experiments of Prof. Guthrie “On Approach caused by Vibration,” and has so well summarised in popular language the facts investigated and the conclusions arrived at, that fitting opportunity appears to present itself to me for calling the attention of the scientific world to phenomena closely allied to those under review although more complex in their manifestation, since in these velocity is independent of, yet initiates vibration. That they have not been referred to in the experiments either by Prof. Guthrie, Challis, and others who have taken part in the discussion is probably to be accoueted for in the unfortunate although convenient habit indulged in by experimentalists of using the tuning fork as the agent for demonstration.
