Heat and light from the sun are from the activity of an intervening substantial ether, a still higher substance capable of more complex motion. Electricity is but another manifestation of the same substance, a substance so subtile and so underlying grosser matter that it is able to operate upon the forces that bind atoms together, and to rend asunder the hardest objects.
