NOTICE.

THIS volume will be found uncommonly rich in new and important scientific facts. It will not probably be often our lot to include so great a number in so small a compass. This is partly owing to the sudden opening of the Continent, which has enriched the historical article commencing the volume with a vast number of new facts, many of them of great importance. The two most prominent papers in a scientific point of view are, 1. The experiments by Berzelius on the composition of organized bodies. It brings a new kingdom under the dominion of chemistry; while the uncommon accuracy of Berzelius has given a degree of perfection to his labours that could hardly have been expected. 2. Gay-Lussac's paper on Iodine. It proves to be a very interesting body; and the new views which its properties lay open greatly increase the interest which the scientific chemist must take in these investigations.
