for the more easy combination of the contained metal or metals with the lead." Claim.-"What I claim as my invention is, the exposing of the ore or ores, or combination or admixture of the precious metals with foreign materials, together with metallic lead and charcoal, sal ammoniac, or other flux, in closed vessels, in which the whole may be subjected to red heat, for the purpose of causing the precious metal or metals to combine with the metallic lead, instead of amalgamating the same with mercury, for the purpose and substantially in the manner set forth, without intending to confine myself to any particular mode of constructing the apparatus used, but to vary this as I may think proper, whilst the principle of In the appaoperation remains the same. ratus I claim, in combination with the vessel containing the molten lead, and provided with an aperture for the discharge of the impurities, and another for the discharge of the lead, the rotating plate, provided with the hollow arber for the supply of the ore, &c., and with the teeth for carrying the ore towards the periphery, substantially as set forth. And finally, I claim the method, substantially as herein set forth, of charging the apparatus with the ore, &c., without admitting air, in combination with the method of carrying the ore, &c., through the apparatus, and over the surface of the lead in the vessel, as described." FOR AN IMPROVEMENT IN THE MACHINE FOR OPERATING, WORKING, OR MANIPULATING MORSE'S ELECTRO-MAGNETIC TELEGRAPH. Edward R. Roe. The patentee says,-" My invention consists, 1st, of moveable metallic types, as conductors of electricity or galvanism; 2nd, a metallic type bed upon which they are to rest (which is also moveable to and fro, somewhat in the manner of a common printing press ;) and 3rd, a moveable board, which is also a conductor, and is made to traverse the face of the types, thereby making, continuing, or breaking the galvanic circuit, according to the forms of the types." Claim.-"What I claim as my invention is, 1st. The combination of the body, the socket, the spiral ring, and the wand, with its conducting point and its non-conducting inclined planes, the whole constituting the and its wand, and its conducting point, guarded by non-conducting inclined planes.' THE UNREASONABLENESS OF SCIENCE. (From Punch.) " An individual named Charles Cameron, a chemist, has put an advertisement in the Times, addressed to the subscribers to the Royal General Annuity Society, soliciting their votes at their next election, on the 30th instant, and also to non-subscribers, requesting pecuniary assistance; for every five shillings on the day of election would, he says, secure him five votes. The claim of this Mr. Cameron to the consideration of the benevolent rests principally on the circumstance that "he was the first who discovered and made public that splendid light which has long been employed at the Polytechnic for displaying the minute wonders of creation by the opaque microscope, to the gratification and mental improvement of millions." A mighty pretty title this to national gratitude! The idea of anybody thinking to be rewarded for discovering a new light, or contributing in any way to the enlightenment of his countrymen ! To have the slightest reasonable expectation of a decent annuity, a man ought to have cut an army to pieces, or destroyed a fleet, or burnt an arsenal, or at least blown up a bridge. Not any mischief in the world has Mr. Cameron done, and yet here he comes forward to ask for remuneration. What do we, the British public, care about science, or those who cultivate it? what good does it do us to know anything about the minute wonders of creation? Talk of the gratification and mental improvement of millions!-The misery and destruction of millions would have been a better recommendation for Mr. Cameron. But, as he is now in the seventy-fourth year of his age, and for the last two years has been in extreme distress from having lost the use of his right arm: whilst, since the gold medal of the Society of Arts has been twice awarded to him, there can be no doubt of his scientific merits; it is very probable that some weak-minded persons may be disposed to succour him, and we reluctantly pander to the morbid susceptibility of such people by stating that any contribution for that purpose may be sent to Joseph Clinton Robertson, Esq., Editor of the Mechanics' Magazine, 166, Fleet-street, before the 30th inst. Considering the kind of estimation in which science and scientific men are generally held among us, we do not wonder that Mr. Cameron has been for three years an unsuccessful applicant for the bounty of the Annuity Society; and now that he has once more applied for it we can only say we wish he may get it. CHANCERY COUrt. [Before Vice-Chancellor Wigram, 17th July, 1849.] BETTS v. WALKER AND BREFFITT. This was a motion by the Solicitor-General (Mr. Webster was with him) to restrain the defendants from making bottles, which the plaintiff alleges to be made in violation of his patent of 30th December, 1844, for an invention intituled "Certain improvements in bottles, jars, pots, and other similar vessels, and in the mode of manufacturing, stopping, and covering the same,”the infringement complained of being the making of the neck of each bottle with what the plaintiff calls an internal bearing shoulder. The defendants (who carry on business as the Aire and Calder Bottle Company) make their bottles under a patent which they have purchased, and which was granted to A. S. Stocker on the 28th May, 1846, for an invention intituled "Improvements in the manufacture of bottles and other similar vessels, and in the manufacture and application of the whole or part of the articles to be used;" and they contend that the inventions are distinct. Mr. Page Wood, Q. C., Mr. Hindmarsh, and Mr. Smith appeared for the defendants to oppose the motion; and after a short discussion, an order was made, by consent, that the motion should stand over until the plaintiff shall try an action and establish his patent in a court of law.

IT cannot now be doubted even by the most sceptical, but that GUTTA PERCHA must henceforward be regarded as one of the blessings of a gracious Providence, inasmuch as it affords a sure and certain protection from cold and damp feet, and thus tends to protect the body from disease and premature death. Gutta Percha Soles keep the feet WARM IN COLD, AND DRY IN WET WEATHER. They are much more durable than leather and also cheaper. These soles may be steeped for MONTHS TOGETHER in cold water, and when taken out will be found as firm and dry as when first put in. Gutta Percha Tubing, Being so extraordinary a conductor of sound, is used as speaking tubes in mines, manufactories, hotels, warehouses, &c. This tubing may also be applied in Churches and Chapels, for the purpose of enabling deaf persons to listen to the sermon, &c. For conveying messages from one room to another, or from the mast-head to the deck of a vessel, it is invaluable. For greater distances the newly-invented ElectricTelegraph Wire covered with Gutta Percha is strongly recommended. Mill Bands. The increasing demand for the Gutta Percha strapping for driving bands, lathe-straps, &c., fully justifies the strong recommendations they have everywhere received. Gutta Percha Pump Buckets, Clacks, &c. Few applications of Gutta Percha appear likely to be of such extensive use to manufacturers, engineers, &c., as the substitution of it for leather in pump buckets, valves, &c. These buckets can be had of any size or thickness WITHOUT SEAM or JOINT, and as cold water will never soften them, they seldom need any repair. Gutta Percha Picture Frames. The Gutta Percha Company having supplied HER MAJESTY THE QUEEN with several elaborate Gutta Percha Picture Frames for Buckingham Palace, which have been highly approved by the Royal Family, fully anticipate a great demand for frames from the nobility throughout the country. In order that the picture-frame makers may not be injured, the Company will supply the trade with the mouldings, corner and centre pieces, &c., and allow them to MAKE UP the frames. Pattern books for the trade are now ready. Gutta Percha soles, solution, inkstands, card-trays, medallions, picture-frames, brackets, mouldings, indow-blind cord, soap-dishes, tap-ferrules, cornices, vases, fire-buckets, bowls, pen-trays, stethoscopes, thin lining, thread, flower-pots, ear-trumpets, &c., &c., manufactured at the Company's Works, Wharfroad, City-road, London; and sold by their Wholesale dealers in town or country. Smoke Nuisance. GODSON'S SMOKE-PREVENTING APPARATUS may be seen in Operation every day at Becket's Steam Mills, Barbican; by which the most sceptical may be satisfied that the Nuisance can be perfectly got rid of. The same apparatus has also been successfully applied in Her Majesty's Dockyards, Woolwich and Portsmouth, To Inventors and Patentees. MESSRS.
