The original folly of the nation, and of Napoleon, in plundering the Continent of statues and pictures, inevitably led to retribution, on the first reverse of fortune. The plunder of money, or of arms, or of anything consumable, would have been exempt from this mortification; but pictures and statues are permanent things, and always capable of being re-demanded. Their plunder was an extension of the law of spoil unknown in European hostilities, or in history, except perhaps in the old Roman ravage of Greece. Napoleon, in adopting the practice of heathenism for his model, and the French nation--in their assumed love of the arts violating the sanctities of art, by removing the noblest works from the edifices for which they were created, and from the lights and positions for which the great artists of Italy designed them--fully deserved the vexation of seeing them thus carried back to their original cities. The moral will, it is to be presumed, be learned from this signal example, that the works of genius are _naturally_ exempt from the sweep of plunder; that even the violences of war must not be extended beyond the necessities of conquest; and that an act of injustice is _sure_ to bring down its punishment in the most painful form of retribution. _The Artesian Well._--Near the Hôtel des Invalides is the celebrated well which has given the name to all the modern experiments of boring to great depths for water. The name of Artesian is said to be taken from the province of Artois, in which the practice has been long known. The want of water in Paris induced a M. Mulot to commence the work in 1834. The history of the process is instructive. For six years there was no prospect of success; yet M. Mulot gallantly persevered. All was inexorable chalk; the boring instrument had broken several times, and the difficulty thus occasioned may be imagined from its requiring a length of thirteen hundred feet! even in an early period of the operation. However, early in 1841 the chalk gave signs of change, and a greenish sand was drawn up. On the 26th of February this was followed by a slight effusion of water, and before night the stream burst up to the mouth of the excavation, which was now eighteen hundred feet in depth. Yet the water rapidly rose to a height of one hundred and twelve feet above the mouth of the well by a pipe, which is now supported by scaffolding, giving about six hundred gallons of water a minute. Even the memorable experiment confutes, so far as it goes, the geological notion of strata laid under each other in their proportions of gravity. The section of the boring shows chalk, sand, gravel, shells, &c., and this order sometimes reversed, in the most casual manner, down to a depth five times the height of the cupola of the Invalides.
