This advertisement for the Ammoniaphone appeared in 1886, by which time it claimed 5,000 testimonials and 650 press opinions. The Ammoniaphone was a tube of 26 inches loaded with a chemical compound intended to resemble the soft balmy air of the Italian peninsula. Users are claimed to have included the Prince of Wales and the UK Prime Minister (of the time) Gladstone. It was indicated for almost every affection of the lungs, and all for just $8.00 to the New York based Ammoniaphone company.
Thanks to Bob Sokol for the picture of an Ammoniaphone. It was supplied in London by The Medical Battery Company of Oxford Street (lower advert)
