"...invented his apparatus in Porto Alegre, and as soon as he arrived in São Paulo in 1896, he began with preliminary experiments, to achieve his object — to transmit human voice to a distance of 8, 10 or 12 kilometers, without using any wires". (The three listed distances referred to the transmission ranges for his megaphone, optical photophone, and radio devices respectively.) Initial development A report reprinted in the June 14, 1899 Jornal do Commercio stated that Landell had successfully conducted spoken-word wireless transmissions over distances exceeding 7 kilometers, "using the ether, telluric currents and electrified air" and employing an approach that was "entirely different from those of European inventions". The next month a notice in the July 16, 1899 Jornal do Commercio, dated the previous day, reported that "Father Landell de Moura will hold an experiment on wireless telephony tomorrow" and "various authorities, men of science and representatives of the press are invited to attend". However, there does not appear to be any additional information about this demonstration. A year later, the June 10, 1900 issue of the Jornal do Commercio reported that on June 3 Landell made a public wireless telephony demonstration in the town of Alto de Sant Anna in the city of São Paulo, and the witnesses included P. C. P. Lupton, the British Consul, and his family. Shortly thereafter, the newspaper's June 16, 1900 issue printed the text of a letter Father Landell sent to Lupton prior to the demonstration, which noted that he would only be able to demonstrate five of his numerous inventions: the "Telauxiofono", "Caleofono", "Anematofono", "Teletiton" and "Edifono". In 1907 The Brazil of To-day provided English language descriptions of these devices: Telauxiofono (also spelled "telauxiophono" and "telauxiophone") "is the last word of the telephone, not only because of the force and intelligibility with which it transmits the words, but also because with it telephoning at great distances becomes a practical and economical reality." Caleofono (also spelled "caleophono", "kaleophono" and "kaleophone") "works also with wire, and presents the originality of not needing to ring the bell to call, to hear the articulated sounds, or that of the instrument." Anematofono (also spelled "anematophono" and anematophone") and teletiton "are wireless telephones. The perfect operation of these apparatus, according to what their inventor says, reveals laws entirely new and is altogether most curious." Edifono (also spelled "ediphono" and "ediphone") "is useful to purify and soften
