Professor Bommsenn's Germ by Ernest George Harmer is an option, a short story published in 1887. The story is available on the website technoccult here. A short description from the site is
A scientist uses electricity to evolve a germ into an evolved human. The mutant human has no teeth or hair and possesses some sort of mesmeric ability. A “spoof of current biology.”
