    "verified_text": "cavallo, tiberius (1749-1809), anglo-italian electrician and natural philosopher, was born on the 30th of march 1749 at naples, where his father was a physician. in 1771 he came to england with the intention of pursuing a mercantile career, but he soon turned his attention to scientific work. although he made several ingenious improvements in scientific instruments, his mind was rather imitative and critical than creative. he published numerous works on different branches of physics, including _a complete treatise on electricity_ (1777), _treatise on the nature and properties of air and other permanently elastic fluids_ (1781), _history and practice of aerostation_ (1785), _treatise on magnetism_ (1787), _elements of natural and experimental philosophy_ (1803), _theory and practice of medical electricity_ (1780), and _medical properties of factitious air_ (1798). he died in london on the 21st of december 1809.",
