1928 K. Meadowcroft Invisible Bubble in Amazing Stories Sept. 510/2 At this intensity the rays very nearly approach the magnitude of the ‘cosmic rays’ of Millikan. They are apparently harmless to life but they seem to be closely associated with the dimensional relations of matter.
1931 C. A. Smith Beyond Singing Flame in Wonder Stories Nov. 759/2 In these worlds, our brains would be attuned to the comprehension or apprehension of vaster and higher scientific laws, and states of entity beyond those of our present dimensional milieu.
1931 C. A. Smith Beyond Singing Flame in Wonder Stories Nov. 754/1 After all, we know little or nothing of the actual nature of space; and perhaps, in some way that we cannot imagine, the infinite is doubled upon itself in places, with dimensional folds and tucks, and short-cuts whereby the distance to Algenib or Aldebaran is merely a step.
1933 H. P. Lovecraft Dreams in Witch-House in Weird Tales July 102/1 The hidden cults to which these witches belonged often guarded and handed down surprizing secrets from elder, forgotten eons; and it was by no means impossible that Keziah had actually mastered the art of passing through dimensional gates.
1944 L. Brackett Veil of Astellar in Thrilling Wonder Stories Spring 59/2 I could remember those alien years. Dimensional walls are no barrier to thought. You lie under the X-crystals and watch them pulse from mist-gray to depthless black. Your mind is sucked out of you and projected along a tight beam of carefully planned vibration, and presently you're in another space, another time.
1946 M. W. Wellman Solar Invasion in Startling Stories Fall 17/1 The rapid classification of facts that had led to his decision about the dimensional theft of the Moon, that had amazed even his companions, was not as effortless as it had seemed—it was only that Curt Newton could and did think and decide, as Otho had said, with the rapidity of light.
1947 E. Fennel Black Priestess of Varda in Planet Stories Winter 11/2 He was quite familiar with the theory of alternate worlds—his work with bound charges had given him an inkling of other dimensions, and the fantastic idea that bound charges existed simultaneously in two or more ‘worlds’ at once, carrying their characteristic reactions across a dimensional gap had occurred to him frequently as his experiments had progressed.
1963 L. del Rey The Sky Is Falling in Two Complete Novels 11 ‘You mean dimensional travel?’ Dave asked. He'd seen something about that on a science-fiction television program.
1970 H. P. Lovecraft Dreams in Witch House in At Mountains of Madness & Other Novels 135 The hidden cults to which these witches belonged often guarded and handed down surprising secrets from elder, forgotten eons; and it was by no means impossible that Keziah had actually mastered the art of passing through dimensional gates.

Lovecraft Dreams in Witch House in At Mountains of Madness & Other Novels 135 The hidden cults to which these witches belonged often guarded and handed down surprising secrets from elder, forgotten eons; and it was by no means impossible that Keziah had actually mastered the art of passing through dimensional gates.
1985 P. C. Hodgell Dark of Moon xiii. 255 The Book had helped her to escape by ripping a hole through to the next threshold world. As far as Jame could remember, she had had to jump out the window to take advantage of that dimensional portal, or perhaps she had simply fallen through it.
1986 D. Carey Battlestations! vi.94 Power waves, maybe. Dimensional tampering. Whatever it was, I hated it.
1995 L. Watt-Evans In Empire of Shadow xxii. 304 She reached back through the‥through the dimensional barrier, she took the phrase from some unguarded, unrecognized mind somewhere. She reached into Faerie.
