86 THE ORIGIN OF CREATION. 



wire ; but in the present state of electric science, wo cannot tell, 

 or even conjecture on any ground of probability, whether the 

 true positive electricity is that which is commonly so-called; 

 or," etc. 



Prof. Tyndall also says in his lectures on "Heat:" "We 

 have every reason to conclude that heat and electricity are both 

 modes of motion ; we know experimentally that from electricity 

 we can get heat, and from heat that we can get electricity. 

 But although we have, or think we have, tolerably clear ideas 

 of the character of the motion of heat, our ideas are very 

 unclear as to the precise nature of the change which this motion 

 must undergo, in order to appear as electricity ; in fact we know 

 as yet nothing about it." 



Prof. Grove says : " How the phenomena are produced to 

 which the term attraction is applied, is still a mystery." 



In Prescott's " History of the Electric Telegraph " which is a 

 compilation of facts from Dela Eive we read : " The theory 

 most generally admitted is that there are two electricities, 

 each composed of particles that mutually repel each other." 

 What would be the use ef two electricities, having the same 

 properties ; in fact we cannot see how there could be two, if 

 they had the same force. Moreover, two differing electricities 

 could reciprocate, while two similar ones could not. We do 

 not see either how a message could be sent along the wires, if 

 the particles mutually repelled each other. If on the contrary 

 they mutually attracted and repelled, there might be some 

 common sense in it. 



From the quotations given, it will now be seen how little is 

 really known about either electricity or magnetism, and it is no 

 wonder, seeing the manner in which they have been mixed up,
