Mode of engraving union steel and then transferring the same to steel or other metals.—This invention deservedly demands while it receives the admiration of every lover of the Fine Arts; and at the same time it presents the means of perpetuating whatever is beautiful in the art of engraving, and will probably produce a general refinement in the state of the public by furnishing engravings of the most beautiful kinds, at the same cost as those of inferior execution.
This invention promises to be of great advantage to some of our manufacturers, particularly that of pottery, which may now be embellished with beautiful engravings, so as to place the successful competition of other nations at a more distant period. It may also be applied with great advantage to calico printing, by producing entire new patterns upon the cylinders from which they are printed, an object of great importance to our manufacturing interest. These are among its obvious applications; but as a means of rendering forgery impracticable, it claims the attention of statesmen and the gratitude of philanthropists, who shudder at the hundreds of victims which are now immolated to the laws by the facility with which they may be violated.
The association of Mr. Charles Heath with the American inventors is a fortunate circumstance, as it affords a pledge, that all which is exquisite in art will be combined with the ingenious mechanical inventions of Mr. Perkins, and the perseverance of Mr. Fairman; and the means of conferring every desirable perfection on various applications of the Siderographic process.
Great Britain and the U. States.—(A Contrast.)—A correspondent observes, that from an article in the last Inquirer, taken from a London paper, it is computed that the expense of the approaching coronation of his Britannic Majesty, George IV., will exceed eight hundred thousand pounds sterling.
This, at $4 44 cents the pound sterling, amounts to the moderate sum of three millions five hundred and fifty two thousand dollars, of the currency of the United States.
This sum would pay the salaries of the President of the U. States for a succession of one hundred and forty-two years,—and leave a balance of two thousand dollars remaining.

English Churn.—An improvement has been made in England in the construction of the dasher of the churn, which "is made to turn on a pivot, fixed in the lower end of the handle, and consists of two pieces set crosswise, so as to form four wings, diagonally shaped, and something similar to those of a windmill. Let the wings be about two inches wide, proportioned in length to the dimensions of the churn, and of such a level as gives them an inclination of about forty-five degrees.
The pivot on which the wings turn to be of iron, otherwise it will soon wear out."
The above plan is more efficacious than any other, and requires the operation to be moderately performed lest the butter come too soon, and therefore become swetted.
