1 The history of a particular department of knowledge, up to the time when the individual appeared by whom its boundaries were extended. 2 A _general_ sketch of the life of such individual, with _particular_ details of the improvements effected by him. 3 The progress of such branch of knowledge, from the date of such improvements up to our own times. The following subjects will be immediately published: Smeaton and Lighthouses. Sir Joseph Banks and the Royal Society. Sir Humphrey Davy and the Safety Lamp. Linnæus and Jussieu; or, the Rise and Progress of Systematic Botany. Cuvier and his Works; or the Rise and Progress of Zoology. Brindley and Canals. Watt and the Steam-engine. Wedgwood and Pottery. Telford and Roads and Bridges. Caxton and the Printing Press. Galileo and the Telescope. Sir Isaac Newton and the Progress of Astronomical Discovery. Sir Christopher Wren and St. Paul’s Cathedral. Addison and the English Essayists. Jeremy Taylor and some Account of his Times and Works. Wilberforce and the Slave Trade. Each work being a Popular Biography, with an Historical Introduction and Sequel. III. Popular Science and Art. When we contemplate the arts and processes of civilized life, we cannot but be struck with the vast amount of invention and ingenuity required for their gradual development. Not an article of clothing or of furniture, not an instrument, implement, or machine, could have been brought to the state in which we find it, without many successive steps of invention, due to different minds, supplied at different times, and brought to light in different countries. But in devoting several of our volumes to the Useful Arts, we shall not be unmindful of the fact, that Art is the application of Science to a practical end. It is proposed, therefore, under the comprehensive title of _Popular Science and Art_, to include portions of our knowledge of animate and inanimate nature. The object will be to assist the general reader to regard with an intelligent eye the varied phenomena of nature, to gratify the laudable desire of understanding what he sees, and of preparing him in some measure to enter more fully upon the study of a given subject. In this way, it is hoped to effect a useful purpose, by connecting Science and the Useful Arts; for “it is not, surely, in the country of Arkwright, that the Philosophy of Commerce can be thought independent of Mechanics; and where Davy has delivered lectures on Agriculture, it would be folly to say that the most philosophic views of Chemistry were not conducive to the making our valleys laugh with corn.” The works already prepared, or in course of preparation, for this division, comprise the following subjects: The Useful Arts employed in the Production of Food. 2_s._ 6_d._ The Useful Arts employed in the Production of Clothing. 2_s._ 6_d._
