68 THE ORIGIN OB 1 CREATION. 



through it. The waves being communicated through the ether, 

 which is everywhere and in everything, glass included, of course 

 it goes through it to our eye. But suppose we hold a piece of 

 cloth before us which is much more porous than glass we 

 cannot see Jupiter. Waves and ether, therefore, have nothing 

 whatever to do with seeing the star, but sight and a transpar- 

 ent medium, everything. 



Lastly, if a fire is lighted a mile or two away during the day, 

 we see only the smoke ; the flame is not visible at all ; while at 

 night the light only is visible. What is to be said of the waves 

 of light during the day ? 



From what we have remarked, light at a distance must be 

 regarded only as a question of sight, and the Undulation theory 

 will have to follow its predecessor Emission, into oblivion. 



Prof. Tyndall, in his lectures in New York, stated, that while 

 it was quite logical for any one to insist, that sufficient evidence 

 might be brought forward in the future, to overthrow the undu- 

 latory theory of light, just as other theories as widely accepted 

 had been given up before, yet it was as unlikely to be over- 

 thrown, as the theory of gravitation. If our theory is correct, 

 which we are endeavoring to prove then the foundation of 

 security on which he has built his hopes, is gone, for we adduce 

 enough proof in another chapter to insure its rejection.
