In Glen Bever's story "And Silently Vanish Away" a chemist with the unique ability to use psychokinetic catalysis to speed up difficult reactions is shocked by a lab explosion and the mixture he was working on gets changed. Under analysis the structure never appears to be the same twice and when the substance is injected into lab rats they start to silently and suddenly vanish. It is found that one part of the compound is a molecule which spreads out into four dimensions. The four-dimensional molecule is thiotimoline. The story appeared in the November 1971 issue of "Analog Science Fiction/Science Fact".
