to be recommended to those who wish for a knowledge of the trade of Germany. ART. 33.-Die wichtigsten Kunstpradwele der fabriken & manufacturen vorzuglich in Europa, von J. C. Moller. 8vo. Hamburg. The most important Productions of the Workshop and Manufactures, particularly in Europe. A Manual for Instructors of Youth in Technology and Geography. This is a very useful publication. The author has collected with great industry a variety of materials from the many very costly works on the same subject. The objects are arranged according to the kingdoms of nature to which they respectively belong. On each production is given the art of cultivating and manufacturing it, and then the various places are mentioned where it is produced or manufactured to the best advantage. Thus the article gold is treated of under the following heads: The obtaining of it from the mines: its natural qualities: the places whence it is "procured: the uses of gold, particularly in coinage: manufactures of gold, as by goldsmiths, goldbeaters, gold-wire drawers. Every part is treated concisely, but sufficiently at large for instruction. Some articles, as may be expected in such a work, are omitted; but this can scarcely be said to detract materially from the utility of a work which will be found very useful in the early part of edu cation. ART. 34.-Reise uber den Sund, &c. Travels to the Sound. Tübingen. 1804. These Travels are not of great extent, but comprehend many statistical details of importance. The account of Bernstorff and his nephew, and of the property near Copenhagen settled by the king on this family, contains many curious particulars; and the history of the extinction of servitude which does this family so much ho nour, is particularly worthy of attention. Estates that used to be sold at four or five hundred rix-dollars, have risen to ten thousand; and on many of these estates, which have come into the hands of citizens of Copenhagen, very considerable improvements have been made. For a property of this kind twenty thousand rix-dollars were lately asked, and eighteen thousand bid for it: and in fact Denmark, by the new ordinance, seems to be a new creation,. All are in action; the labour is infinitely more productive; and the peasantry are approaching fast to the old state of English yeomanry. ART. 35. Antangs grunde der unbestimmlrn Analytik, Sc. Principles of Unlimited Equations, for the Use of those who have no Instructor. By D. J. C. L. Hellig. Jena. This part of the mathematics is one of the most interesting, but it is much less cultivated than from its importance it deserves. More would perhaps apply themselves to this branch of know. ledge, if its merits were more extensively known, and if the pre judices against it from obscurity and imagined difficulties were removed. The unlimited analysis, which it is the intention of this writer to explain in an easy manner, is a part only of the higher arithmetic, or rather a practical application of it to the solution of unlimited equations, by whole or at least rational numbers. The principles of the art depend on the arithmetical theory of the functions of two or more variable quantities, provided they can be expressed in whole or rational values. From the great improvement made in later times in the higher arithmetic, the solu tion of unlimited equations is brought to a considerable degree of perfection: but it was not the object of this writer to enter far into this subject; he wished only to introduce the student to the easier processes, and he has so well succeeded, that with a very slight degree of attention, every difficulty will be overcome by a novice at first in the art; and on finishing the work he will be qualified to enter upon the most abstruse enquiries. The work is divided into two parts: the first containing equations of one, the > other of two dimensions; and the instances, taken chiefly from Euler, are numerous and well calculated for a young beginner. ITALY. ART. 36. Porta Foglio Militare, &c. Military Port-folio: under the Patronage of the Government of the Italian Republic. Milan, 1805. This is a monthly publication on an excellent plan, but most miserably executed. The intention is to introduce, even into the lower classes of the army, knowledge and instruction. The table of contents will shew what the work would lead us to expect; but every part is so negligently performed, that the Italian army is not likely to receive much benefit from the production. 1. On patriotism. 2. Instruction and knowledge necessary for a soldier. 3. Patience a quality requisite in an officer exercising a recruit. 4. The duty of a common soldier. 5. Brief instructions for subalterns in the light troops. 6. Life of Montecuculli. 7. The duty of an adjutant. 8. Thoughts on the tactics of infantry and cavalry. 9.
