More, they, or some of them, had learned the use of the Fourth
Dimension, that is their most instructed individuals, could move through
opposing things, as well as over them, up into them and across them.
This power these possessed in a two-fold form. I mean, that they could
either disintegrate their bodies at one spot and cause them to integrate
again at another, or they could project what the old Egyptians called
the Ka or Double, and modern Theosophists name the Astral Shape, to

had this faculty were, she said, also very apt at reading the minds of
others and therefore not easy to deceive.

Life-water?" asked Bickley.

"Yes," she answered, with her unvarying smile. "At the moment I spoke

see you take the water from the fountain and guess the purpose, and,
secondly, whether perhaps Bastin did not tell me what you were doing

"Look here," said the exasperated Bickley, "I admit that telep
