181 the thought is transferred; it is converted into a particular kind of motion in his aura and then into action in the nerve-fluid and is thus immediately transmitted to his brain.

If the will-power of the operator is not strong enough to give a direction to the vibration generated in the astral fluid, touch is generally required; and where there is magnetic sympathy or at least absence of repulsive tendencies, the vibration immediately reaches its destination and is transferred into a thought in the mind ot the sensative, which will be the same thought first generated in the mind of the operator. If a particular sort of motion in nerve-fluid means a certain thing in the mind of one man, it means the same thing in another man's mind.

The ideas of modern scientists about luminiferous ether are hardly sufficiently definite to enable us to express an opinion about their resemblance to our views, but from the manner in which the conclusions have been arrived at, we see certain differences.

First, we see light coming to us from the fixed stars, and they say, admitting the undulatory theory of optics, there must be a medium through which the vibrations pass.

Secondly, they have ascertained from minute mathematical calculations that, owing to friction in this ether, there is a certain amount of retardation in the path of the planets. Admitting the two premises, it will be plain that the ether exists throughout space; now the astral fluid does not exist throughout space, but âkâsh does, and the latter is more likely to correspond with the ether of the scientists.

Their cosmic ether is not peculiarly permanent in connection with any particular organism and does not appear to have any special connection with nerve force, but we hold that whenever there is a specially sensitive organization, the astral fluid is there concentrated, and in other places it exists more or less uniformly diffused, but its uniformity is never continuous like that of the ether of the scientists.
