On arriving home the duke received him in the friendliest manner, and he was promoted to Helmstedt, where with the assistance of his patron he published his DISQUISITIONES. On January 1, 1801, Piazzi, the astronomer of Palermo, discovered a small planet, which he named CERES FERDINANDIA, and communicated the news by post to Bode of Berlin, and Oriani of Milan.
I say his purpose, because, whoever originated the scheme, Cheops carried it out; it was by means of his wealth and through his power that the pyramid was built. This is the view adopted by Professor Piazzi Smyth and others, in our own time, and first suggested by John Taylor.
Principles of Geology, 11th edition, vol. ii. p. 48. Smyth, Report on the Teneriffe Astronomical Experiment of 1856. Humboldt makes the elevation 12,090 feet. A beautiful model of the Peak was constructed by Mr. J. Nasmyth from Piazzi Smyth's plans, of which photographs are given by the latter. Daubeny, loc. cit., p. 460. Iles Canaries, p. 37. Daubeny, loc. cit., p. 426. Jour. Geol.
The discoverer is Professor Piazzi Smyth, who has presented a minute account of it in a paper in the Practical Mechanic's Journal for October 1850, and also separately in a pamphlet. We invite public attention to this curious but simple invention, of which we shall proceed to present a few principles from the pamphlet just referred to.
'People of sense don't judge a place at ten o'clock of a pitch-dark, rainy night, especially if they are hungry, tired, and, excuse me, love, rather cross, returned Amanda, severely, as they piled into a carriage and drove to Piazzi di Spagna. 'I see a divine fountain! A splendid palace! Now it's a statue of some sort! I do believe that dark figure was a monk!
Still, the desire to measure this parallax was only intensified by the practical certainty of its existence, and by repeated failures. The attempts of Bradley failed. The attempts of Piazzi and Brinkley, early in the nineteenth century, also failed. The first successes, afterwards confirmed, were by Bessel and Henderson.
The young men read him shrewdly, but speaking was useless. Before Carlo parted from Luciano, he told him the burden of the whisper, which had confirmed what he had heard on the Piazzi d'Armi.
On the evening of March 29, 1807, the diligence of Olbers was rewarded with the discovery of the fourth of the group, which like its predecessors, was so small and irregular in character as still further to favor the fragmentary theory. How shall we name the asteroids? Piazzi fell back upon pagan mythology for the name of his little world, and called it Ceres, from the Roman goddess of corn.
Piazzi Smyth, who during a prolonged visit to this mountain in 1856 made a careful survey of its form and structure, shows that the great cone is surrounded by an outer ring of basalt enclosing two foci of eruption, the lavas from which have broken through the ring of the outer crater on the western side, and have poured down the mountain.
He published two memoirs relative to Mars, the one in 1781, the other in 1784, and the discovery of its being flattened at the poles we owe to him. After the discovery of the small planets, Ceres, Pallas, Juno, and Vesta, by Piazzi, Olbers, and Harding, Herschel applied himself to measuring their angular diameter.
