Infinite vibrations

"We see objects within the limits which make up our colour spectrum, with infinite vibrations, unused by us, on either side of them. If we could conceive a race of beings which were constructed in material which threw out shorter or longer vibrations, they would be invisible unless we could tune ourselves up or tone them down. It is exactly that power of tuning up and adapting itself to other vibrations which constitutes a clairvoyant, and there is nothing scientifically impossible, so far as I can see, in some people seeing that which is invisible to others. If the objects are indeed there, and if the inventive power of the human brain is turned upon the problem, it is likely that some sort of psychic spectacles, inconceivable to us at the moment, will be invented, and that we shall all be able to adapt ourselves to the new conditions. If high-tension electricity can be converted by a mechanical contrivance into a lower tension, keyed to other uses, then it is hard to see why something analogous might not occur with the vibrations of ether and the waves of light."
