Tongue-in-cheek references to this story were made in at least two scientific publications in the 1960s. The first panel of the second page was reproduced in "Chemical and Engineering News" for June 16, 1969, to accompany an article on carbene chemistry. Notes and synopsis by Michael Barrier from "Carl Barks and the Art of the Comic Book" (M. Lilien, 1982).
