Relative to the Bath water, so high in public estimation, the Doctor's observations merit particular attention. On this subject he remarks; "From the various facts I have stated, I believe it may be regarded as the more probable opinion in such cases, that the original ingredients are sulphate of soda and muriate of lime. Since sulphate of soda exists in the Bath water, and since muriate of soda and sulphate of lime are obtained in its analysis, it is scarcely possible to refuse assenting to the conclusion that these are formed by the action of sulphate of soda on muriate of lime. On this view of the composition of the Bath water, it is easy to assign the proportions of the ingredients, from the products which are obtained in its analysis. In the formation of 3.3 grains of muriate of soda, which is the quantity obtained from a pint of the water, 3.1 grains of muriate of lime must be decomposed four grains of sulphate of soda would be required to produce this decomposition; and at the same time 38 grains of sulphate of lime would be formed. "The latest, and no doubt the most accurate, analysis of the Bath water, that by Mr. Phillips, gives the following view of its composition. Carbonate of lime Silica "But, considering the composition according to the preceding view, the ingredients and thei proportions will be, Sulphate of lime.... 5.2 grains Carbonic acid.. 1.2 inch Muriate of lime ...... .... 3.1 Sulphate of soda........ 5·5 Oxide of iron 0.8 0.2 position of the Bath water, com"The peculiarity in the compared with the greater number of saline mineral waters, is that it phate of soda than is necessary to contains a larger quantity of sulconvert its muriate of lime into sulphate of lime." The waters of Cheltenham and Harrowgate then pass under Dr. M.'s view; which is finally extended to those of some of the springs: respecting which he obmost celebrated foreign mineral serves, Seltzer, form a very valuable "Those of Spa, Pyrmont, and order of mineral waters, to which country-what have been called we have none analogous in this the alkaline carbonated waters, distinguished by the leading character of being largely impregcontaining a considerable pronated with carbonic acid gas, and portion of carbonate of soda. With this are associated carbonate of magnesia, carbonate of lime, and muriate of soda. Now this association of muriate of soda with these earthy carbonates, while there is also carbonate of soda present, leads almost necessarily to the belief that the real ingredients are carbonate of soda, muriate of magnesia, and muriate of lime; that the carbonate of soda is in larger proportion than what is indicated by the analysis; that it acts during the evaporation of the water on the muriates of magnesia and lime, and forms the carbonates of these earths which are obtained with corresponding portions of muriate of soda and that it is only what muriate of soda there may be above this that exists as an original ingredient. "The Seltzer water, which is the purest of this order of waters, as containing neither iron nor any sulphate, affords in particular a very excellent illustration of this. It contains, according to Bergman's analysis, in an English pint, Carbonic acid gas. 17 cub. in. 4 "But adopting the opposite view, the composition, so far as the uncertainty of the state of the products, to which Bergman's estimate is referred, admits of calculating the proportions, will be, Carbonic acid gas. 17 cub. in. > Muriate of lime.... 3:3 grains Muriate of magnesia 5 Muriate of soda . 7.8 Carbonate of soda. 10-3 dry, or 15 crystallized." M. LE ROUX has published, in the 94th volume of the Annales de Chémie, a paper on the " Means of preventing the Developement and Propagation of contagious Typhus," in which he states, that the following fumigations have been found effectual for this purpose. For rooms not inhabited,—mix three ounces of common salt with two drachms of black oxide of manganese, in an earthen vessel; and then pour two ounces of sulphuric acid (oil of vitriol) upon the mixture. If the earthen vessel be placed on a heated stove before the sulphuric acid is poured in, the salt will be more completely decomposed than without the heat. A small additional quantity of salt, however, has been found to answer the purpose of heating. When the rooms are inhabited, -a small quantity of salt is to be put in an earthen vessel, and a few drops of sulphuric acid poured in successively. This must be repeated four or five times a day. Disinfecting flasks may be prepared by putting four ounces of muriatic acid, two drachms of black oxide of manganese, and half a drachm of nitric acid, (common aqua-fortis), into a large flask, and closing it with a ground glass stopper; and opening it occasionally, when necessary to destroy any putrid miasmata diffused through the atmosphere. For sulphurous fumigations, mix equal quantities of flowers of sulphur and nitrate of potash together; and throw eight or nine grains of this powder, when occasion requires, on a charcoal stove. Nitric fumigations are prepared by putting about four drachms of concentrated sulphuric acid into a glass vessel or crucible. This is to be placed in a sand bath, and when slightly heated, a little nitrate of potash is to be thrown in occasionally. The salt is slowly decomposed, and an acid gas diffuses itself through the atmosphere; and these small apparatus may be placed in different parts of a sick room, without inconvenience. Sulphurous fumigations are the best for purifying bedding, clothes, &c. M. GUALTEER DE CLAUBRY has made some experiments on the peculiar substance which M. | Rose extracted a few years since from the root of the elecampane; and to which he gave the name of Inuline. From these experiments, he concludes that Inuline is a peculiar substance, which cannot be confounded with any other vegetable substance, and that it ought to be classed among the immediate materials of vegetables. M. VAN MONS states it as his opinion, that what are usually termed Meteoric Stones, are neither projected from the moon, nor generated in the atmosphere, as philosophers have generally supposed; but are formed of the substance of the soil, which the lightning puts into a state of fusion. He saw a globe of fire strike the ground within a few paces of him, accompanied with WORKS PREPARING FOR PUBLICATION. Mr. Sutcliffe of Huddersfield, Civil Engineer, will shortly publish a truly national work, peculiarly calculated to interest the mechanic; the manufacturer, the canal proprietor, the farmer, the corn miller, and the corn dealer. The work will comprise distinct treatises on Cotton Spinning, observations on the different Canals and Railways in England and Ireland, Draining Lands, and a new and improved method of preserving Grain, and also of purifying that which is become fusty and unfit for use.

A. has in the press, a new Erlition, being the Fifth, of his work, entitled, Oriental Customs; it has been revised throughout, and instead of forming two series of references to various passages of Scripture, rated in one arrangement. The first volume will comprise the Books of the Old Testament to the end of Solomon's Song. The second, from the beginning of Isaiah to the end of the New Testament. Additions will be made to the extent of nearly 100 pages of entirely new matter, containing extracts from some recent valuable Travels, and a copious list of Eastern literature.
