The papers read in the various sections were numerous, and some of them are described as of very remarkable freshness and value. They will soon be accessible in the published Transactions, which will this year be more voluminous than ever. The retiring President, Dr. Robinson, at the opening meeting, congratulated himself on being able to surrender his dominion to his successor in a more prosperous condition than he had received it, and spoke in glowing terms of the character and scientific achievements of that successor, of whose labors he gave a brief but glowing history. Sir David Brewster, who was one of the founders of the Association, is a native of Jedburgh, in Roxburgshire; where he was born December 11, 1781. He was educated for the Church of Scotland, of which he became a licentiate; and in 1800 he received the honorary degree of M. A. from the University of Edinburgh. While studying here he enjoyed the friendship of Robison, who then filled the Chair of Natural Philosophy; Playfair, of Mathematics; and Dugald Stewart that of Moral Philosophy. In 1808, he undertook the editorship of the "Edinburgh Encyclopaedia," which was only finished in 1830. In 1807 he received the honorary degree of LL. D. from the University of Aberdeen; and in 1808 was elected a Fellow of the Royal Society of Edinburgh. Between 1801 and 1812 he devoted his attention greatly to the study of Optics; and the results were published in a "Treatise on New Philosophical Instruments," in 1813. In 1815 he received the Copley Medal of the Royal Society for one of his discoveries in optical science; and soon after was admitted a Fellow of that body. In 1816, the Institute of France adjudged to him half of the physical prize of 3000 francs, awarded for two of the most important discoveries made in Europe, in any branch of science, during the two preceding years; and in 1819, Dr. Brewster received from the Royal Society the Rumford gold and silver medals, for his discoveries on the Polarization of Light. In 1816 he invented the Kaleidoscope, the patent-right of which was evaded, so that the inventor gained little beyond fame, though the large sale of the instrument must have produced considerable profit. In 1819, in conjunction with Dr. Jameson, he established the "_Edinburgh Philosophical Journal_"; and subsequently he commenced the "_Edinburgh Journal of Science_," of which sixteen volumes appeared. In 1825, the Institute of France elected him a Corresponding Member; and he has received the same honor from the Royal Academies of Russia, Prussia, Sweden, and Denmark. In 1831, he received the Decoration of the Hanoverian Guelphic Order; and in the following year, the honor of Knighthood from William the Fourth.
