2942. THAT INTERIOR SPIRITS HAVE A SUBTLE PERCEPTION, WHICH IS COMMUNICATED TO ME. It is granted to observe that spirits are aware whom they can use as objects, when they plot anything, whom they forthwith sent to me, that they might be their stationary [agents]: further I have now also observed, that they have perceived, who was with me, whom they wished cunningly to separate from me [one], nevertheless, when I have not noticed [observed] spirits [can] also when permitted take many things forth from my memory, while I know nothing thereof; thus while I am awake and while asleep as it were read things which are in my memory consequently many things unobserved by me - from which it may be inferred, that they when permitted can likewise [take forth] from other memories, and these not know it. - 1748, August 26.
