This gallery needs JavaScript — but you can read the entries directly: Airship, Radium, Electricity, and the rest are all in the A–Z.

Rights & ReuseThe complete text of Aiton’s Encyclopedia (1910) is in the public domain in the United States — like all works published before 1928 — and is free to read, download, quote, teach from, and reuse. This digital edition (its transcription, restored images, and site design) is © 2026 PhotoOpAI, and any editorial commentary we add is clearly marked as ours; the underlying public-domain text carries no such restriction.
