    blow-pressures. All these can be converted into mechanical readjustments of molecules, and so pro- mote nerve-cell action. Indeed, there can only be rare occasions for the intervention of separate electrical stimulation for general or clinical purposes, or outside the laboratories. Here, clinically and generally, the mechanical chain of evidence is complete.^ Even the opposites, as thirst, hunger, or weariness, should be ^ The chief support of the theory of the electric origin of the nerve impulses relies on the galvanometer and the presence of electric currents. But, besides being too feeble to have any effect, their more or less universal presence, and the constant presence in other tissues, and in all chemical actions, must tend to be non-differential, and practically a tonic condition ; except with the enormously strong laboratory test. (The usual electro- mathematical formulae do not explain the transmission.) And, certainly, the varying degrees of ordinary stimuli to nerves have little or nothing to do with electricity, whereas pressure stimuli are well adapted to all the circumstances of nerve stimulation, and they can be demonstrated : from a blow to tickling ; from heat to the play of light upon the eyes or our well-being ; from muscle tone, as muscle pressure to all pathological chemical action, as Caries, or chemical physiological actions. As to the medium the new condition of a physical substance will be explained as a probable accompaniment of atomic struc- ture in the subsequent Section on Bio-Mouldings. \Vide^. i8o.] That substance provides an unbroken chain for the immediate delivery of nerve pressure influence in any degree, and in an elastic way from their sources, along the nerves, to the nerve- centres.
