method of tinning, or covering with tin, sheets or plates of copper, brass, or zinc. June 10, 1817. THOMAS WHITTLE, a wharfinger at Chester, and GEORGE EYTON, of the same place, gentleman; for a new or improved kiln, for the purpose of drying malt, wheat, oats, barley, peas, beans, and other substances, by means of steam, assisted by air. June 10, 1817. Under the head of Patents we have to announce to our readers that Mr. Leger Didot (not Roger, as mentioned by mistake, in the list of new patents contained in our last number) has just completed the specification of his patent for improvements upon the machines already in use, for making wove and laid paper, in continued lengths, or separate sheets; and we do it the more especially, as from the great length of the specification, and the extensive drawings necessary to elucidate it, there seems little probability of its being made public in any other way. In the improved machines the ordinary paper moulds can be carried forwards in an endless succession, and paper made upon them in sheets, with the usual wire marks, just the same as by hand, or it may be made of any required length, and without the marks. The same machine will also make paper upon an endless revolving wire web, as in a former patent machine of the same artist. ARTICLE XV. Scientific Books in hand, or in the Press. The second part of the second volume of the Memoirs of the Wernerian Natural History Society will appear the first week in January. Mr. Parkes has just completed a new edition of his Chemical Catechism. Dr. Adams is about to publish a new edition of his Life of Mr. John Hunter. Mr. Mill's History of British India is just ready for publication. J. C. Curwen, Esq. M. P. is about to publish Letters written during a Tour in Ireland: they are principally on subjects connected with the Agriculture and internal Prosperity of that important Portion of the United Kingdom. The Rev. J. Yates, M.A. is about to publish four Discourses on the Effects of drinking Spirituous and other intoxicating Liquors. This work is designed to serve as a popular and practical treatise, combining powerful persuasives, derived from the influence of spirituous liquors upon the morals and the understanding, with an accurate description of their effects upon the bodily frame; in compiling which the author has availed himself of the opinions and testimonies of Drs. Willan, Lettsom, Heberden, Linnæus, Rush, Trotter, Beddoes, Aikin, and various other writers. ARTICLE XVI. Magnetical and Meteorological Observations. Bushey Heath, near Stanmore.
