As may be seen, Mr. Garnier's project presents conditions which are very favorable to the establishment of an elevated road in the interior of Paris. Far from injuring the aspect of the great arteries of our metropolis, the viaduct, as it has been conceived, will contribute toward giving them a still more imposing look. If the beautiful is, as has been said, the expression of the useful, an elevated railway, well conceived, may be beautiful. The project of a subterranean railway is attended with great drawbacks, not only as regards the great expense that it would necessitate, but also the difficulties of constructing it. And there is a still graver objection to it, and that is that it would oblige travelers to move like moles in dark, cold, and moist tunnels. At Paris, where we are accustomed to a pleasant climate and clear atmosphere, we like plenty of air and broad daylight.--_La Nature._ * * * * * ENGINEERING INVENTIONS SINCE 1862.[1] [Footnote 1: Address of Sir Frederick Joseph Bramwell, F.R.S., on his election as president of the Institution of Civil Engineers. January 13, 1885.] By Sir F. J. BRAMWELL. I propose to devote the very limited time at my disposal to the consideration of some of the most important of those improvements which are obviously and immediately connected with civil engineering. I am aware of the danger there is of making a serious mistake, when one excludes any matter which at the moment appears to be of but a trivial character. For who knows how speedily some development may show that the judgment which had guided the selection was entirely erroneous, and that that which had been passed over was in truth the germ of a great improvement? Nevertheless, in the interests of time some risk must be run, and a selection must be made; I propose, therefore, to ask your attention while I consider certain of (following the full title of Division I.) "The apparatus, appliances, processes, and products invented or brought into use since 1862." In those matters which may be said to involve the principles of engineering construction, there must of necessity be but little progress to note. Principles are generally very soon determined, and progress ensues, not by additions to the principles, but by improvement in the methods of giving to those principles a practical shape, or by combining in one structure principles of construction which had been hitherto used apart. Therefore, to avoid the necessity of having a pause, in referring to a work, by finding that one is overstepping the boundary of principle, and trenching within the domain of construction, I think it will be well to treat these two heads together.
