the phonographed voice of the parasitical vibrations, reproducing it just as the natural voice." In his letter Landell also proposed that, with the support of British government, he could continue research to commercially develop his inventions, being compensated only for living expenses and the funds needed to continue his studies and scientific experiments. In addition, he offered to establish two facilities in England, dedicated to providing care for the sons and daughters of soldiers recently killed in the Second Boer War. However, the British government did not take him up on his offer. In late 1900, a Rio de Janeiro newspaper carried an article about an English invention, Colonel George Edward Gouraud's "Gouraudphone" (rendered as Gouraudphono in Portuguese), which was a high-powered megaphone designed for long-distance communication. Contemporary accounts describe the Gouraudphone as a "talking foghorn": a sound amplifier that operated by "working a piston-valve in a cylinder and vibrating a current of air or gas, entering another cylinder and vibrating a large diaphragm which gives out an imitation of the original sounds. The intensity of the sound can be increased by having more than one piston and cylinder regulating air currents, so that the speech might be heard for several miles." Dr. José Rodrigues Botet took exception to this report, and the December 16, 1900 issue of the La Voz de España carried a letter from him insisting that it was actually Landell who deserved credit for developing the underlying technology used by the Gouraudphone. Botet's letter stated that over the years he had personally witnessed Landell, working alone, develop advanced wire and wireless telegraphy and telephony equipment, while never receiving the recognition he deserved as "Brazil's eminent son". 1901 Brazilian patent Landell received his first patent, no. 3,279, from the Brazilian government on March 9, 1901. It covered a device for providing two-way "Phonetic transmission at a distance, with or without wire, through space, Earth and water". Two configurations were described: a full design, known as the "Tellogostomo", and a simpler version, called the "Telauxiophone": Tellogostomo: The construction information stated that the full assembly was divided into four boxes. A telescope, compass, and level were attached to aid correct orientation of the communicating units. Also specified was a "compulsor", described as "an electric fan of great speed of rotation", which, because of the noise it made, had to be turned off when receiving. The design included a "photophore",
