possibility of the existence of the mind after the disruption of 
the body, in substance absolutely imperceptible to our senses, yet 
forming organisms which may be as evident and substantial to 
each other as are our material bodies to each other, 
So far all this is pure hypothesis. We have only offered as 
evidence for the existence of a psychic substance the seeming in- 
capability of the brain to serve as a mental basis. Yet other evi- 
dence exists of considerable force and value. We know that a 
psychic substance must exist for the same reasons that we know 
an ether exists. We cannot see, touch or weigh either, but there 
are phenomena in nature which we cannot possibly comprehend 
without them. We believe in the ether because there are things 
done in the universe which matter could not possibly do. We 
may find ourselves forced to believe in a psychic substance for 
reasons of the same kind. 
If masses of matter send out radiations of light and heat which 
affect distant masses of matter, then psychic masses, when actively 
excited, should send out parallel radiations which will affect other 
psychic masses, but fail to act upon matter. Evidence of the 
existence of such a condition is by no means rare. Every mind 
seems to send out psychic radiations which flow like light rays 
through ether in every direction, weakening with distance. At 
least by such a hypothesis we can understand some very remark- 
able mental phenomena which now stand as incomprehensible 
mysteries. These we can but briefly glance at. One very com- 
mon instance of this, which has occurred to most people, is the 
tendency to think and speak of a person immediately before he 
appears. Some indication of his coming seems to be in the air, 
but as an influence that acts not on the senses but directly on 
the mind. In certain instances persons declare that they can see 
a mental image of every approaching friend. If our hypothesis 
be true, it must be that every mind sends out radiations peculiar 
to itself, as every physical object does, that this peculiarity is 
recognized by the receptive mind, and consciousness directed 
thereby to the mental image of the person to whom the emissive 
mind belongs, precisely as it would if we saw some physical object 
belonging to that person. : 
When the emissive mind is actively exercised and is strongly 
thinking of the receptive person, this influence may be carried to 
much greater distances, and may rouse the consciousness of the
