Observatory: the hemispherical dome was built by the Cooke House of York in 1885, with a diameter of 31 ft, manual movements, iron frame and paper-machè cover (pressed cardboard). The telescope and the dome were purchased second-hand by Cerulli, having already been used in

But Cooke's interest in mathematics and science was practical as well academic. He had also retained his interest in navigation and instruments, and while at
