THE YOUTH’S CABINET. sociate traveler. From Paris, Humboldt set out for Madrid, with a good collection of instruments; for he had for several years cherished the design of traveling within the Tropics at his own expense. In 1799 the court of Spain granted him permission to travel through the Spanish colonies in America. He im- mediately sent for his young friend Bon- pland, who lost no time in joining him, and they set sail from Corunna, for Ame- rica. The plan of travel which these two friends sketched for themselves was laid out upon a more extensive scale than that of any journey before undertaken by pri- vate persons. Five years was the period in which they proposed to explore distant regions; and in that space of time, prob- ably no two individuals ever collected: so much useful information, and returned home so richly laden with rare specimens in the different departments of science. They took home with them, on their return in 1804, an herbarium containing more than six thousand species of plants. The pre- paration of the observations made during this tour, and the publication of works relating to it, occwpied the time of these travelers for several years after their re- turn home. The various works relating to this journey comprised seventeen folio and eleven quarto volumes, well illustrated. The results of this expedition have been of the highest importance to science. ~ In natural history, especially, these observa- tions of six years exceed anything that has been presented by the most success- ful investigators of this field during a whole life-time. His valuable works on the subject of plants, alone form an era in» the history of botany. In October, 1818, Humboldt visited 285 was a resident of Paris, and there devoted himself to the sciences. During the winter of 1822, the king of Prussia called Humboldt to accompany him on a journey through Italy. While residing at Naples, his attention was di- rected to inquiries concerning the forma- tion of volcanoes, the result of which he gave to the public in a small essay. On finishing this tour he again returned to Paris, where he remained till the latter part of 1826, when he went to Berlin, and delivered a course of lectures ‘on the phys- ical constitution of the globe, which was attended by the court and royal family. He next undertook an important jour- ney through Northern Asia, as far as the borders of China. In this he was assisted by the Russian government, which wished to obtain, through him, more correct in- formation respecting the character and contents of the Ural mountains. On his return, he published an account of his re- searches in those regions. In 1845 he published the first volume of the “Cosmos,” and completed it in 1847. This is a valuable contribution to physical science. Another work by him, entitled “ Views of Nature; or, Contem- plations on the Sublime Phenomena of Creation,” has recently been published in London. Baron Von Humboldt’s renown has extended over all parts of the civilized world; and, at the present day, there is not a man of science in Europe whose name is more familiar. And this eminent philosopher is still living, having attained an age of more than fourscore years, Well may he be called the patriarch of modern science. At the present time he is the friend London. For several years afterward he | and companion of the king of Pruassia,
