THOUGHTS ON NATURAL PHILOSOPHY. 57 



The author, in order to convince sceptics, has had 

 a working model of a dynamo and electric light plant 

 constructed ; and he has given demonstrations and 

 explanations to scientific and practical audiences, 

 with the result that all agreed that his theory has 

 been irrefutably proved to be fact. 



More convincing *proofs than the above it would 

 be difficult to find in science or nature. 



The term most likely to cause confusion in the 

 mind of the reader in considering this theory is the 

 well-known expression, gravitation ; but this is 

 merely a word for a form of force not clearly com- 

 prehended by the users, and therefore to be depre- 

 cated as unsatisfying and unsatisfactory it is, in 

 fact, a non-explanation. An explanation may be 

 found in the following ideas. The ether is matter, 

 this is proved by abundant electrical phenomena, 

 amongst the most interesting and convincing of 

 which are, perhaps, those in connection with wire- 

 less telegraphy.t " Hertz discovered that electrical 

 oscillations, produced in a so-called open electric 

 circuit possessing capacity and inductance, create in 

 the surrounding ether a disturbance which is called 

 an electric wave. This wave can be detected at a 

 distance by means of devices which are now termed 

 Cymoscopes or Wave Detectors." Marconi, working 

 on this basis laid by Hertz, utilized electric waves 

 for telegraphic purposes. Marconi's great discovery 



* Nature and science abound in proofs; is it necessary to fill a library 

 with them ?
