- The Spectroscope, an Instrument for Analysing Light
This pictorial diagram illustrates the principal of Spectrum Analysis, showing how sunlight is decomposed into its primary colours. What we call white light is composed of seven different colours. The diagram is relieved of all detail which would unduly obscure the simple process by which a ray of light is broken up by a prism into different wave-lengths. The spectrum rays have been greatly magnified. - The Triumphal Return of Columbus to Spain
The successful voyager lost no time in reaching Barcelona, where he was received by the king and queen with triumphal honors. Everybody was ready to praise the man who had become so famous. There was a great procession in his honor in the streets of Barcelona. Leading this street parade were six Indians whom Columbus had brought back with him. These were smeared with paint, decked with feathers of tropical birds, and ornamented with bits of gold. Following them came men carrying stuffed and live birds of brilliant plumage, and the skins of different animals, all products of the New Land. Columbus rode on horseback, attended by many of Spain's great men, mounted on horses.
