revisited his native country, where he found that in his absence he had been promoted to the degree of Doctor in Medicine. He was now elected a member of the Royal Society of Stockholm, and, after the death of Baron de Geer, was appointed conservator of his collection of natural history, which had been bequeathed to that body. Some time after, he was made president of the same learned institution,--an office which he resigned in three months. In 1787, he accompanied his friend Wadstroem on an expedition into the interior of Western Africa; but the project failed, and in the following year he returned to the Swedish capital, where he continued till his death in July 1820. The principal works which he published are, 1. A Voyage to the Cape of Good Hope, to the South Polar Circle, and round the Globe, with a Journey into the Country of the Hottentots and Caffres. This book has been translated into English. 2. The Musaeum Carlsonianum, containing Descriptions of the rarer Animals in the Collection of Baron Carlson. 3. A Discourse on the Advantages of Expeditions to the Pacific Ocean, with Descriptions of Animals and Plants. CHARLES PETER THUNBERG was born in Sweden in 1743, and died at Upsal in 1828. In 1770, after finishing his education, he went to France, and from thence to Holland, where, on being recommended by Burmann, he was engaged by the Dutch East India Company to go to Japan in a medical capacity. After remaining some time at the Cape, he proceeded to his destination, and afterwards to Java and Ceylon, whence he returned first to England, and subsequently to Germany. His travels occupied nine years. Fourteen months after the death of Linnaeus, he was appointed director of the botanic garden of Upsal during the absence of the son of that renowned professor. He acquired the honours usually bestowed on fortunate cultivators of science, and finally succeeded the younger Linnaeus. Besides these celebrated individuals, who explored the most remote regions of the globe, many of the students trained in the garden and lecture-rooms of Upsal traversed various parts of Europe. Koehler visited Italy; Alstroemer the same country, as well as France and Spain; Von Troil made a voyage to Iceland; Fabricius travelled in Norway, England, and France; and Solander examined the Lapland Alps. In short, an astonishing impulse was given to the study of natural history in general, and of botany in particular. Facts and observations were accumulated to such a degree, that had Linnaeus lived ten years longer he would have been utterly unable to continue the legislator of the science in all its departments. To him, however, remains the glory of having been the only individual who described all the minerals, plants, and animals, known in his time. Before him no one had attempted the task.
