OV 1.4 1 util i I,The abstract, philosophic nature of the ether dream gives it a special interest to students of philosophy and psychology. By its Intensely specific character it differs entirely from the opium or hasheesh hallucination. The opium eater may dream of a thousand different things, but the other patient invariably has one fixed impression—a belief that the ultimate secret and explanation of existence stands revealed to him as finite knowledge never lias or never could reveal it. The singular thing is that this impression may happen to a man who has never given one. thought to philosophy, and | whose mind, therefore, is void of material ! for this impression. This fact, and the sie-; cific likeness of effect of the ether on all who I have made the experiment, had led some i psychologists to declare the impossibility of ; considering the phenomenon a dream, and to claim place for it as genuine philosophic insight. _
