Meda: a Tale of the Future as Related by Kenneth Follingsby is an early mutant fiction written in 1888, printed for private circulation in 1891, and finally published in 1892. It’s an exceedingly rare book – I traveled to Riverside, CA to read it last November. I’m quite excited to see it online.
You can get it in several formats at archive.org
