IN acquainting our readers that the present number concludes the Fourth Volume of the New Series, we beg to call their attention briefly to the peculiar -claim to support which the work possesses, namely, that of giving, in addition to the matter usually contained in publications of the kind, a descriptive account of EVERY newly-patented invention and discovery as soon as they are enrolled in Chancery,—a species of information, although of the highest interest, and of the utmost practical value, has never before been presented to the public but in a very partial degree. The machinist and the inventor, who propose to speculate in a patent, may therefore through this medium be always informed of what other ingenious individuals have accomplished before them, and thus in numerous instances avoid disappointment and loss, while the philosopher will be gratified in having constantly exhibited to him a correct view of the progress of art and science. A reference to the Index will at once shew that several hundred new patents are described in the present volume. The Editor has likewise to announce that having made some arrangements, by which he will be able to devote more time to the work than he has done recently, he hopes that the succeeding volume will evince a considerable improvement in the matter as well as the illustrations.
