468 Dr. II. Hare's Objections to the Theories severalli/ of 



from? How can a current of quantity in a ribbon coil* give 

 rise to one of intensity in a coil of fine wire, rushing of course 

 with a velocity commensurate with the intensity thus imparted? 

 S^. From the preceding considerations, and others which 

 will be stated, it follows, that it has been erroneously inferred 

 that the only difference between galvanic and frictional elec- 

 tricity is dependent on quantity and intensity. It must be 

 evident that there is a diversity in the nature of these affections 

 of matter, sufficient to create a line of demarcation between 

 them. 



25. Having stated my objections to the electrical theories 

 heretofore advanced, it may be proper that I should suggest 

 any hypothetical views which may appear to me of a cha- 

 racter to amend or to supersede those to which I have objected. 

 But however I may have been emboldened to point out 

 defects which have appeared to me to be inherent in the 

 theories heretofore accredited, I am far from presuming to 

 devise any substitute which will be unobjectionable. I am 

 fully aware that there is an obscurity as respects the nature 

 and mutual influence of chemical affinity, heat, light, elec- 

 tricity, magnetism and vitality, which science can only to a 

 minute extent dispel. 



26. The hypothesis which I now deem preferable is so 

 much indebted to the researches and suggestions of Faraday 

 and others, that, were it true, I could claim for myself but a 

 small share of the merit of its origination. That sagacious 

 electrician emjjloys the following language: — "/« the long- 

 continued course of experimental inqtiiiy in ichich I have been 

 engaged, this general result has pressed upon me constantly, 

 namelij, the necessity of admitting two forces or directions of 



force combined "jcith tlic impossibility of separating these two 

 forces or electricities from each other" — Experimental Re- 

 searches, 1163. 



27. Subsequently (1244), after citing another proof of the 

 inseparability of the two electric forces, he alleges ?V to be 

 ^^ another argument in favour of the view that ijiduction and its 

 concomitant phccnomena depend upon a polarity of the particles 

 of matter ! " 



Supposed grounds for a Theory. 



28. The grounds upon which I venture to advance a theory, 

 are as follows: — 



The existence of two heterogeneous polar forces acting in 

 opposite directions, and necessarily connate and co-existent, 

 yet capable of reciprocal neutralization, agreeably to the
