444 APPENDIX.25. Having stated my objections to <strong>the</strong> electrical <strong>the</strong>ories heret<strong>of</strong>oreadvanced, it may be proper that I should suggest any hypo<strong>the</strong>tical viewswhich may appear to me <strong>of</strong> a character to amend or to supersede those towhich I have objected. But however I may have been emboldened topoint out defects which have appeared to me to be inherent in <strong>the</strong> <strong>the</strong>oriesheret<strong>of</strong>ore accredited, I am far from presuming to devise any substitutewhich will be unobjectionable. I am fully aware that <strong>the</strong>re is an obscurityas respects <strong>the</strong> nature and mutual influence <strong>of</strong> chemical affinity, heat, light,electricity, magnetism, and vitality, which science can only to a minuteextent dispel.2G. The hypo<strong>the</strong>sis which I now deem preferable is so much indebtedto <strong>the</strong> researches and suggestions <strong>of</strong> Farraday and o<strong>the</strong>rs, that, were ittrue, I could claim for myself but a small share <strong>of</strong> <strong>the</strong> merit <strong>of</strong> itsorigination.That sagacious electrician employs <strong>the</strong> following language : "/??<strong>the</strong> long-continued course <strong>of</strong> experimental inqiiiry^ in loliich I have Jjcenengaged,this general result has pressed u^jon me constantly— namely, <strong>the</strong>necessity <strong>of</strong> admitting two forces or directions <strong>of</strong> force, combined with<strong>the</strong> imiiossi.hilify <strong>of</strong> separating <strong>the</strong>se two forces or electricities from eacho<strong>the</strong>r." (^<strong>Experimental</strong> Researches, 1163.)*27. Subsequently, (1244,) after citing ano<strong>the</strong>r pro<strong>of</strong> <strong>of</strong> <strong>the</strong> inseparability<strong>of</strong> <strong>the</strong> two electric forces, he alleges it to he ^^ ano<strong>the</strong>r argument infavour <strong>of</strong> <strong>the</strong> view that induction and its concomitant phenomena dependupon a polarity <strong>of</strong> <strong>the</strong> particles <strong>of</strong> matter VSup)posed grounds for a Theory.28. The grounds upon which I venture to advance a <strong>the</strong>ory are asfollowsThe existence <strong>of</strong> two heterogeneous polar forces acting in opposite directions,and necessarily connate and coexistent; yet capable <strong>of</strong> reciprocalneutralization, agreeably to <strong>the</strong> authority <strong>of</strong> Farraday and o<strong>the</strong>rs : <strong>the</strong>polarity <strong>of</strong> matter in general, as displayed during <strong>the</strong> crystallization andvegetation <strong>of</strong> salts : also as made evident by Farraday's late researches,and <strong>the</strong> experiments and observations <strong>of</strong> Hunt : <strong>the</strong> very small proportion<strong>of</strong> <strong>the</strong> space in solids, as in <strong>the</strong> instance <strong>of</strong> potassium and o<strong>the</strong>r metals,which are apparently occupied by <strong>the</strong> ponderable atoms ; while, agreeablyto <strong>the</strong> researches and speculations <strong>of</strong> Farraday, (rightly interpreted,) <strong>the</strong>residual space must be replete with imponderable matter : <strong>the</strong> experimentsand inferences <strong>of</strong> Davy and o<strong>the</strong>rs, tending to sanction <strong>the</strong> idea that animponderable e<strong>the</strong>real fluid must pervade <strong>the</strong> creation : <strong>the</strong> perfect identity<strong>of</strong> <strong>the</strong> polarizing effects, transiently created in a wire by subjection to agalvanic discharge, with those produced by <strong>the</strong> permanent polarizing power<strong>of</strong> a steel magnet : <strong>the</strong> utter heterogeneousness <strong>of</strong> <strong>the</strong> powers <strong>of</strong> galvanicand frictional electricity, as respects ability to produce sparks before contact,and likewise <strong>of</strong> <strong>the</strong> polarities which <strong>the</strong>y respectively produce : andsuperficiality <strong>of</strong> electricity proper during discharge as well as when existingupon insulated surfaces, as demonstrated by atmospheric electricity whenconveyed by telegraphic wires, agreeably to Henry ; <strong>the</strong> sounds observed* This seems to have been cntirel}' overlooked in his suggestions respecting <strong>the</strong> nature<strong>of</strong> material atoms. It appears to me that <strong>the</strong> characteristics thus insisted upon are incompatiblewith tlie idea that each property is <strong>of</strong> itself a diffusible matter, and that in suchatoms two polarities can exist inseparable from each o<strong>the</strong>r.
