First collected in 1961 / original appearances from 1951 to 1957 - in Galaxy (4), Astounding (2), Fantastic Universe, Magazine of F&SF, and If. Not surprisingly for an author who was a physician, many of these involve medical issues in some way. "Nightmare Brother" involves the Hoffman Medical Center, and the title story is a classic about the hazards of attempting to exploit other dimensions.
