entertaining anecdotes of the valour, exploits, and bons mots of the Knights of the Order in question. VI. L’Esprit des Croisades, &c. i. e. The Spirit of the Croisades, or a Political and Military History of the Wars undertaken by the Christians for the Recovery of the Holy Land out of the Hands of Mahometans, during the Eleventh, Twelfth, and Thirteenth Centuries. 8vo. Paris. 1780. There is a great deal of historical information in this Work with respect to the details of a war, dićtated by superstitious ferocity, absurd in its principles and yet, in the wisdom of Providence, the fource of many advantages, which the bigotted combatants neither proposed by it, nor expected from it. The History of the Croisades, by F. Maimbourg, has got deep into the cell of oblivion; and the work before us will sink it still deeper, though the latter (whose Author seems to be both a philosopher and a critic) is rather defeółve in point of style. " ' " ' " " * VII. Introdućlion et Plan d'un Traité General de Navigation Interieure, &c. i. e. The Introduction and Plan of a General Treatise of Inland Navigation, more especially in France ; together with Considerations on Forests, Woods, and other Objećts susceptible of Improvement by the Means of new Communications. To these is subjoined, a Treatise of Tolls and Turnpikes, in which, after a Demonstration of the Advantages that would result from their Suppresfion, a Plan of Indemnification is proposed. ... By M.:ALLEMAND, Ancient Keeper of the Forests in the Island of Corfica. 8vo., Paris. i.780.This useful and instrućtive Work, notwithstanding its modest title, contains all the ideas and materials that might be expećted in a complete and finished treatise, . It is divided into three Sečtions. In the first we find an ample description of inland navigation; also an account of the works and proječts relative to this objećt, which have been executed in ancient times, or are at present carried on in Europe, Asia, and other parts of the world. In the second se&tion, M. Allemandu follows the inland navigation in France from province to province, describes each river, canal, and aquedućt, and shews what has been done, and what is still to do, relative to this important objećt. This leads him to an ample field of discussion and enuiry, in which the difficulties that may attend a circuitous inavigation, by canals of communication, between the great rivers, are particularly considered, the methods of removing them proposed, the advantages that Hust result—from this navigation to the internal state and commerce of the different provinces, and to the commerce of the nation in general, clearly unfolded, the abuses pračtised on the rivers and canals, and the methods of remedying them accurately pointed out, and - ". . . . . . a mul

a multitude of other questions examined, which are conneéted with this interesting subjećt. He observes, among other things, that the forests in France are capable of furnishing the Royal marine with a quantity of ship-timber and masts, that render the importation of this commodity unnecessary, and are equal in quality to that which is procured from the north at a great expence. He tells us also, that the Lariccid pine, or larch of Corsica is of the same nature and utility with that which is used in the Royal docks, and that the pretended difficulty-bf transporting this timber is one of those pretexts by which private interest so often defeats the plans that are formed for public good *. In the third se&tion M. Allemand lays down a plan of administration and condućt in this branch of political ceconomy, which he thinks-adapted to promote and secure the establishment of an inland and circulating navigation with all its advantages. To render more intelligible the operations proposed and recommended in this excellent and useful work, the Author has composed a general chart of the rivers and the internal circulating navigation of France, particular charts of each province, a great number of plates, representing sluices, flood-gates, aqueducts, dykes, and other instruments and works of an hydraulic nature, of which there are several that have been lately invented, and have met with the approbation of the Royal Academy of Sciences at Paris. . The whole of this work is not yet published, but the remainder will soon appear; and as inland navigation is one of the most important obječts of political ceconomy, as it promotes population, gives a vivifying spirit to agriculture, animates commerce, and is a natural and perpetual support to maritime navigation and foreign trade, à work of this kind must be well received in all countries. VIII. Avis aux Citoyens sur les Causes, les divers Caraćières, it les vrai, Remedes de l'Aveuglement, de la Surditë, et des Prin- £ipaux Acciden; Weneriens, &c. i. e. Advice to the Public relative to the Causes, the various Chara&ers and Symptoms, and the irue Remedies of Blindness, Deafness, and the principal Venereal Symptoms. To which are added, important Observations concerning the Property, as yet little known, of certain Means, equally speedy, simple, and effectual, of administering Succour in the following Cases:" 1st, In restoring to Life still-born Children, Persons drowned, and those who have been suffocated by the Vapours of Çoal, Mephiti. Exhalations, &c.—2dly, in • Our Author, after comparing together the qualities of the Corfican Lariccio with the Northern, observes, that a larch of the largest size, imported from the North, costs the French 4ooo livres (about zoo pounds), whereas the price of a Corfican larch of the same dimensions amounts only to isoo livres (about 75 pounds).
