From D0novon's Chemistry. PHILOSOPHICAL FACTS.

The change of properties which takes place when chemical attraction acts, Is not confined tometals, but is general result in every case, where different bodies are brought into this state of combination or chemical union. Frequently we find that ahe properties of each body are totally changed; and that substances, from being energetic and violent in their nature, become inert and harmless, and Uice rerSG. For in- stance, that useful and agreeable substance, culinary salt, which is not only harmless, but wholesome, and absolutely necessary to the well-being of man, is composed of two formidable ingredients either of which ta- ken into the stomach proves fatal to life; one of these is metal, and the other an air the former is called sodium, the latter chtor- .ine. When presented to each other the vi- olence of their nature is manifested by their immediately bursting out into flames, and instantly they are both deprived of their vir- ulence. Can any thing be more striking than the change of properties in this case and who could have supposed that culinary salt is composed of a metal united to an air :! The medium called Glauber's salts is anoth- CT instance; it is composed of two caustic poisons of different kinds; one called oil of Vitriol, and the other barilla of soda. There are also two substances known to chemists, "hASH UlS uiSSuSlttlSly UIllCI OIIC IS called nitrate of silver, and the other hydro sulphate of sodas when mixed they form compound of considerable sweetness. But the atmosphere which we breathe is the most extraordinary of all instances it must be surprising to those who are unacquainted with the fact, that atmospheric air, is con- posed of the same ingredients as that most violent and destructive liquid called aqua ,fortiS, or nitric acid. This powerful acid be- ing made to act upon sugar, the sweetest of all things, produces a substance intensely bitter to the taste. Charcoal is, of all known substances, the most difficult to convert into vapor; so much so, indeed, that the conver- sion has never yet been decidedly effected, it is aIso very solid substance; and dia- mond, which is nothing but crystaliZed charcoal, is one of the hardest bodies in na. ture. Sulphur, in the solid state, is also a quireS high temperature. But when these two substances, carbon and sulphur, arc made to combine chemically SO as to form the substance called bsulphuret of carbon their properties are strikingly changed. In- stead of the compound being hard, it is a thin liquid, and is not known to freeze or so. lidify at any degree of cold that can be pro- duced. Instead of the compound being ditfi- cult to vaporize, it is, of all liquids, one of the most evaporable. Charcoal is the black est substance with which we are acquainted sulphur is of q most lively yellow hue; but the compound is as colourless as water. A new smell and taste arc acquired, and, in q word, there is not one point of resemblance kingly illustrative of the change of proper ties which follows on the exertion of chemi. cal attraction between the ultimate particles of bodies. TO PREVENT COWS FROM KICKING.
 The following article appears to show q very simple method of breaking COWS of an evil habit. It was written some years ago by Mir. Nathaniel Kidder of Prospect, Me, and committed to the Hancock Az. Society, and by the trustees directed to be published in the N. E. Farmer. r.- - t .lf
 SIR-I have noticed that much has been done by the agricultural societies in New England, to encourage the improvement of milch COWS as it respects quantity and quali- ty of milk, but have seen no premium of. fercd for an improvement in the method to prevent COWS kicking their milk ovey after they have given good mess. The methods usually prRctised, believe, are lowing up one fore leg, tying both hind legs together, holding by one person while another milks, holding shovels for them to kick against, whipping, &c. Not one of these is m effec- tual security for tho milk or milker, nor does either of them effectually cure the cow of her bad tricks; SO that after much trouble and many hard knocks it not unfreuuently happens that it is thought necessary to put tho best COWS for milk into the beef tub.- Noticing the position of a COW while kicking, which was to drop the head and crook up the back, thought would try a new and simple method to cure her. After tying her in the stanchels, made ono end of rope fast round her horns, and put the other end over the girt which was about two feet high CT than the top of the stanchels, and about the same distance in front, drew il pretty tight and fastened it to a stud. This so eff. fectually secured her that she was milked with the most perfect ease and safety and after practising this method two or three times she gave mo no more trouble Scye- ral subsequent trials on other COWS have proved this method, not only vastly superior to all others, but an efiectual remedy: nnd it is so easy and simple, that female or n boy can secure a COW without any difficult sty. Another advantage this method has over any other I have heard of, is. that bv keeping tho cows back hollow, it is believ. ed, she cannot hold up her milk.
