ge, and M. Bauerkeller has already
executed those of London, Paris, St. Petersburg, Vienna, New York, the
city of Mexico, Hamburg, Basle, a Panorama of the Rhine from Coblentz to
Mayence, besides several other cities and countries, and there is no
doubt that in a short time the whole of Europe and many other distant
districts will be illustrated in the same manner, as he is constantly
adding to his collection which already excites the highest interest. M.
Bauerkeller's plan of executing charts, maps, or views in relief, can be
equally produced either upon velvet, silk, or leather, for the
illustration of a diversity of subjects which can be applied to an
innumerable variety of purposes, as shades for lamps, men's caps,
slippers, reticules, stands for decanters, screens, etc., etc.; already
he has extended his connexions to such a degree that he receives
applications from all parts of Europe and America for different articles
in which his invention is introduced. Some of his works which were
displayed at the national exhibition excited universal admiration, and
obtained him a medal; he has also been granted a patent for fifteen
years. This invention is not only valuable in having rendered maps more
ornamental, but it assists the study of geography; by the objects being
rendered so much more distinct, it increases the interest and
consequently makes a deeper impression on the memory; in fact, the
numerous advantages to be derived from this system of giving plans in
relief may be easily imagined, but are too long to be described. A
specimen of the art will be found at the beginning of this work: M.
Bauerkeller's address is No. 380, Rue St. Denis, Passage Lemoine.

Amongst the number of inventions which are constantly emanating from the
brain of man, I know of few which unite more ingenuity, utility, and
simplicity than that of M. Martin (gun-maker at No. 36, Rue
Phelippeaux), relative to the improvement of every description of gun
that is impelled by percussion. According to the system he has
introduced, and for which he has obtained a patent, all the
inconvenience to which the sportsman is subjected in priming is entirely
obviated, as instead of having to place the percussion cap with one's
fingers, so disagreeable in very cold weather, it is at once effected by
the act of cocking, and the gun may be fired from 80 to 100 times,
always as it were priming itself, as the number of percussion caps
required are introduced thro
