fact equally important and extraordinary, that one of his pupils is able to repeat, in any order you pleafe, and without the leati mistake, a table of fifty cities in all parts of the world, with the degrees of longitude and latitude in which they are fituated; whereas I, who have for fixty years devoted my attention to geography, cannot repeat four of them. The fame is the eafe with chronology: in the Annuaire I have inferted 210 dates from ancient and modern hiftory, and M. de Fenugle's fcholars repeat then all. I do not think that the ablest historiographer could tell ten of them. What an atomithing aid in the ftudy of geography and hittory!*

M. SINGER, a native of Germany, has obtained from the papal government the exclufive privilege of a branch of commerce of his own contrivance. No perfou at Rome ever conceived the idea of carbonizing turf; and as the cooks employed fcarcely any other fuck than charcoal made from wood, the confumption of that article was eflimated at 3000 facks per day. Hence fome conception may be formed of the quantity of wood required for this purpofe. M. Singer having remarked that the Pontine marthes were capable of fupplying an immenfe quantity of turf, he made from it a kind of charcoal, which has no difagreeable · fell, and which, when ufed for the forge, poffeffes the important advantage of giving more heat than common chaicoal, without injuring iron.

The following account of the very fingular confequences of the bite of a rattle-fuake, is equally curious and interefting. In the former of 1801, Mrs. Alfred Beeman, of Luzerne county in Pennfylvania, was bitten by a rattle-fuake. She was then in the fourth or fifth month of her pregnacy. Notwithstanding the alarmning fymptoms commonly attending the bite of that animal, Mrs. Beeman

MR. WILLIAM NICHOLSON'S (sono SQUARE,) for various Improvements in the Application of Steam to ufeful Pur pofes, and in the Apparatus required to the fame. Granted November 22, 1806. HIS invention, and the manner in Twhich it is to be carried into effect

and practice, are defcribed as follows: Mr. Nicholfon converts water into fteam by the application of heat in any of the ufual methods, and permits the faid fteam to rush out through one or more apertures, of such magnitudes refpectively as may be beft adapted to the feveral purpoles. He then permits the current or currents of fleam to pafs through a portion of the atmosphere, or of air communicating with the atmosphere, or of fuch other gas, or elaftic fluid, or vapour, or fmoke, as it may be defirable should come into contact with the faid fteam. Further, he difpofes a tube or pipe (of a circular bore in preference) in fuch a pofition, with regard to the faid current or currents of fieam and air, or of fteam and gas, claftic fluid, or vapour, or fmoke, as that the faid current or currents fhall pafs through the faid tube or pipe, and be carried to its place of deftination. He alfo gives unto the faid tube or pipe a greater diameter, or uze of perforation, than he allows for the firft efcape of the fcam from the place where the fame was produced; and he makes the faid tube or channel either cylindrical or of fuch other figure internally as may be beft fuited to produce that effect which is well known to men of science by the name of the lateral action of fluids, the effect of which faid lateral action of fluids is particularly to be obferved in the ancient and well-known machine for producing a blaft by the fall of a fhower of water through an upright pipe; and in this invention the lateral action of the current of fteam takes place with regard to the furrounding air, or gas, or elaftic fluid, or vapour, which is carried along with it, fo that the fteam is made to produce an effect of the fame nature as, but more powerful and advantageous than, is produced by the water in the faid ancient machine; and Mr. N. applies the faid current of fleam and air, or of team and gas, elastic fluid or va pour, or fioke, to fuch purposes of manufacturing or philofophical chemistry as may be ufeful according to the nature of the feveral cafes reipęcuvely, namely,

(1) for agitating, or for impregnating, or for driving over in diftillation water or other fluids, or (2) for oxidating, coʻroding, rufting, or altering the nature and state of lead or other metals, or metalte ores, or mineral bodies, more or lefs heated or ignited by the action of bre

tubes, or mutiles, or tefts, or bodies, or veffels, or upon hearths, grates, or otherwife fo placed, fituated, or expofed, as may be beft adapted for the changes intended to be produced in the faid metals, metallic ores, or mineral bodies, by means of the faid current herein before mentioned and defcribed; or (3) he caufes the faid current of fteam and atmofpheric air to pafs through the tube or pipe herein before defcribed, or in fome cafes fimply through an aperture or hole, into a receptacle or air veffel, wherein the team is fubjected to condenfation, and from which velel the atmospheric air, thus deprived of its steam, is conveyed to a furnace or any other place containing fire or burning materials, in order that the faid current or blait of air fhall and may excite and increase the strength, rapidity, and effect of the combustion.

MR. WILLIAM HYDE WOLLASTON'S, (ST. MARY-LE-BONE,) for an Inftrument whereby any Perfon may draw in PerSpective, or may copy or reduce any Print or Drawing. Granted December 4, 1806.

This inftrument confifts principally of two reflecting furfaces, fo placed with regard to each other, as that the first of the faid furfaces fhall be wholly or in part interpofed between the eye of the artit and the paper, or other material on which the delineation of any object or view, or the copy or reduction of any fketch, print, or drawing, thall be intended to be made; and the faid reflecting furface thall be fo inclined toward the fecond reflecting furface, that objects reflected by that fecond reflection may alfo be again reflected by the firit, and may by that means be rendered visible to the eye after two reflections, when the fight is directed towards the faid paper or other material. And, in order that the faid paper or other material may be feen with the fame eye, as well as the doubly-reflected object,the first-mentioned reflector is made of fuch materials as fhall permit the faid paper or other ma terial to be feen through the fame; or the

first reflector is made of materials not capable of tranfinitting the light; and in this cate the fame is interpofed in part only between the eye and the faid paper or other material. In the former cunfruct on the first reflector may be a piece of an unfilvered glass, which is capable of exaibiting the image of a confiderably luminous object by reflection, at the fame time that a piece of white paper or other furace may be feen through the glafs, and the image of that object may be placed upon the faid paper or other fur face; but in cafe the object, be, lefs bright, it may not be thus feen by reflection from clear white glafs diftinctly enough to be delineated, and in this cafe gials that is blue, or of any other dark colour, will be preferable. But it is in general better to ufe for the first reflector aglafs partly filvered, and to allow the paper to be feen through an opening in the filvering, or paft the edges of the fame by que portion of the eye, while the doubly-reflected object is feen in the filvering by the other portion of the fame eve. Thefe glaffes, or other fuitable reflecting furtaces, when properly mounted, and fupported at a convenient diftance from the paper or other material upon which the delmeation is to be made, do, together with the neceffary framing, (which every competent workinan may eatly make of a variety of forms without farther inflruction,) conftitute the inftrument, adapted to the ufe of perfons who can with facility fee both near and diftant objects; but for perfons who are hort-lighted, a fuitable concave glafs is placed before the diftant object, fo as to receive and tranfinit the incident rays; and for long-fighted perfons a fuitable convex glafs may be placed between the eye and the faid paper, or other material.

MR. ROBERT VAZIE, (ST, MARY, ROTHER

HITHE, CIVIL ENGINEER) for Improve ments in the Meafures of Coals in the Machinery for working Pistons; and for Signals for unhired Carriages. Granted November 6, 1806,

To adjust the quantity of coals to be ufed in burning bricks and in baking earthen-wars, upon the outfide of the coal-buihel measure, with which the coals are measured is placed a moveable femis circular metal bow, upon which is tuf pended three moveable bobs or pins of inetal, or other material, fo as to form three guages of fuch length, and at fuch a I distance from each other, as that when the meature is filled with coals to the

height of feven inches perpendicular above the centre of the plane of the top of the meature, the lower part of the guage is equal to the height of the heap, and the lower part of the guages comes in contact with the straight fide of the heap at a mean diftance from the top of the heap to the outfide of the measure; which heap is as nearly in the form of a cone as the nature of the coals will per mit, the outfide of the measure being the extremnity of the base thereof. The bow and the guages are turned down by means of hinges, and lie on the outside of the measure at the time of filling it. Measures thus adjusted may be usefully applied to the adineafurement of coals for household use, and the other purposes for which coals are ufed; and alfo for the meafuring of grain, fruit, roots, and fuch other articles as are ufually disposed of by admeasurement,

To raife the water to be used in tempering and preparing clay, or other materials, for making bricks and earthenware, in preference to a pump with one pifton or bucket, there may be applied a pump with two or more piftons or buckets, in the following manner:-Upon a bar of wood or iron, called a fpear or rod, where is to be fixed the uppermost piston, upon the underside of the faid pifton is to be placed au eye of iron, or other metal, and by means of a book, at the upper end of a feparate bar of wood or iron (upon which bar the undermoft piston is to be fixed) the different pifious are connected together, The diftance between the faið pitons is to be two feet; and for every thirty feet the water is to be raised, ap ply two piftons thus connected together, which rife and fall at one and the fame time by means of a lever, or other ma chinery ufually applied for that purpose. Piftons, thus connected together, may be alfo applied ufefully in a pump to raise water from a mine, fhaft, pit or quarry, or the hold of a fhip, or refervoir for ge neral purposes, or for comprefling or ex haufting air or foam; and the cock may alfo be ufefully applied to retain or draw off liquid matter from a pipe, calk, or refervoir, or a boiler or vat.

The fignal for unhired carriages is placed perpendicularly; and when the carriage is hired the faid fignal is turned down by means of a joint (familar to the joint af a clafp knife,) und lies horizon tally. In the night-time a lanthorn is placed containing a lamp or other light. When the carriage is unhired, the light appears through certain characters cut in a thutter; and when the carriage is hired, Y 2
