This is the anecdote as related to me, and it serves as an illustration of my theory that the unknown brain is objective, and that it can, under given circumstances--_i.e._ when physical life is, so to speak, in abeyance--be both seen and felt by the known brain. At birth, and more particularly at death, the presence of the unknown brain is most marked. And here it may not be inappropriate to remark that, in my experience at least, the hour of midnight is by no means the time most favourable to occult phenomena. I have seen far more manifestations at twilight, and between two and four a.m., than at any other period of the day--times, I think, according with those when human vitality is at its lowest and death most frequently takes place. It is, doubtless, the ebb of human vitality and the possibility of death that attracts the earth-bound brains and other varying types of elemental harpies. They scent death with ten times the acuteness of sharks and vultures, and hie with all haste to the spot, so as to be there in good time to get their final suck, vampire fashion, at the spiritual brain of the dying; substituting in the place of what they extract, substance--in the shape of foul and lustful thoughts--for the material or known brain to feed upon. The food they have stolen, these vampires vainly imagine will enable them to rise to a higher spiritual plane. In connection with this subject of the two brains, the question arises: What forms the connecting link between the material or known brain, and the spiritual or unknown brain? If the unknown brain has a separate existence, and can detach itself at times (as in "projection"), why must it wait for death to set it entirely free? My answer to that question is: That the connecting link consists of a magnetic force, at present indefinable, the scope, or pale, of which varies according to the relative dimensions of the two brains. In a case, for example, where the physical or known brain is far more developed than the spiritual or unknown brain, the radius of attraction would be limited and the connecting link strong; on the other hand, in a case where the spiritual or unknown brain is more developed than the physical or known brain, the magnetic pale is proportionately wide, and the connecting link would be weak.
