BRODIE’S PATENT QUARTZ ORUSHING MACHINE, The annexed engraving represents one of a well known class of machines which is steadily coming into use for reducing the quartz from ths condition in which it is received from the mine to a size suitabls for heing placed under the stamps for further reduction. A large amount of lahor is saved by these macliines, and the rock is much hetter prepared for the stamps than whcn it is dons hy hand. We have hers a perspective view. Was give the inventor’s description as follows : The frame is made of cast iron, bouod with heavy wrought iron bands, makiog it very strong, and at the same time light and portable. The crusher is bolted to a wood frame, of sufficient hight to clear the -fly-wheel, and allow the crushcd quartz to pass off he dotted lines show the movable aud stationory sr LA =. WANVLECK & KEITH, jaws. Letter A represents the sccentric shaft hy which ths power ie applied direct to the movable jaw. Letter B represents the movable jaw, and C the fixed jaw. Letter D represents the link or radius bar. Letter E represents the bolts for regulating the opening, F, which can be regulated at pleasure, so as to graduate to the size to which it is intended the quartz shall be crushed. Letter G represents the feed opecing, by which the size of the machine is designated. The arrow on the fly-wheel shows the direction to drive the eccentric, which, in comhination with the link, D, gives the movable jaw, B, a forward and downward aiotion at the same time, and which makes the hardest rock yield and separate into fragments of any desired size. Those who have witnessed the working of the machine, are astonished at the ense with which it is made to operate, and its simplicity of constructiog and great strength. It is claimed for the machine, that with equal power for work, it is of coosidérahly less weight than other machines of a like character, an item of economy not only as respects original cost, but will he found specially important at mines situate in remote places, and of difficult access. MAGNESIUM IN THE ARTS. Magnesium is now mnde in Boston, on a somewhat large scale, from dolomite or magnesian limestone, by the Sonstadt method. Ths principal usc for the metal hitherto hss been to hurn for light, the acting power of which is 1-36th that of the sun, though the intensity of the light is 1-525th that of the sun. Nuinerous otber employment in the arts will, doubtless, he found for magncsium, as soon as its propertics becoms mors generally gud more fully known. M. Roussin has recently published @ paper oe the action of magnesium on metallic solutions, and on its application to toxicologicsl researches, which shows that magnesinm is particularly well adapted for the precipitation of other metals from solutions of their salts. A large number of very interesting experiments in this direction are reported hy M. Roussin. Among others, he observes thata sodium amalgam, shaken up with an acidulous solution of salt of chromium, or a salt of manganese, changes to an amalgnm of chromium or of manganese, as the case may be; and that ag amalgam of either of these metals, obtained ig the manner indicated, whee distilled in a current of hydrogen, nfter having heee first ) carefully washed ie acidulated water, lenves . tbe pure metal in the form of a fies, spongy powdcr. He shows that magnesium is particularly well adapted for the precipitatioe of other metals from solution of their salts. Quite a eumber of qetals have hitherto resisted all attempts to precipitate them by ths nse of other metals ; but, with two or three exceptions, Mr. Roussin has found that these are all readily precipitated into their metallic state by the use of magcesium. The two exceptions are chromium snd manganese, which are both throwe down, however, bnt ie the condition of oxyds. Aluininum is not precipated at all. Tbe use of magnesium in fireworks gives the lights a most magnificent hrilhancy, such as is attainable in no other way. Several European governments are now engaged in experiments, with the view of its application to light houses and coast and sea signals. It is also hegincing to be used for examinations with the speculum in surgical operatione. For workers and dealers in colors, the magnesiuin light is superior to all others, for the reason thot hy its rays colors can he distinguished as readily as by sunlight. ‘These nre some of the many uses to which magnesium have heen already applied. Further researches, and its cheaper production will, doubtless, ere long, lead to its much more extended and varied opplication in the arts. New Firu.—Messrs.

Tue Use or Cosmetics—CursicaL Pnenomena—Lanigs Beware.—A lady in thiscity, and one somewhat noted for the delicate heanty of her complexion, noticed a few days since, the sudden appearance upon her person of great numbers of pimples, like groups of little volcanoes, which threatened to cover her beautiful neck and arms with pathological arahesques. Under the ‘advice of a physician, whom she had called in, she ordered a medicated hatb ; and with the hesitatton of a womnn of delicate nerves she gradually snbmerged her person. Scearcely, howsver, had the sulphurvus wave enveloped her form, ere, from head to foot, the delicste white of her person was changed to Ethiopian bronze. Ignorant of the fact that the change of color was due te her almost daily habit of whitewashing herself, .80 to speak, from head to foot, and fearful lest the sudden transformatioe of her psrsoe was due to an attack of the cholera, she again hastily summoned her physician, who, when he arrived, could scarcely preserve his dignity oc witnessing the changed appearancs of his patiect. “ Madame” said he, with all the gravity he could summon, “ be not alarmed; you are not ill; you are merely a most remarkable chemical product. You are go longer a woman; you ars a sulphuret. Itis cot now a question’ of medical treatment which Ihave in my hands; but a simple chemical reactiog which I must bring about. I shall analyze you. First I shall submit you toa bath of sulphuric acid, diluted with water. The acid will have the pleasure to combine with you—will tnke np the metal and sulphur with which you have eo plentifully covered your persoa, and will preduce a eulphate. We shall then find, as a precipitate a very pretty womac.” Fair dames, let this incident serve ,you as a lesson—never use a white powder which has a metallic base. Taz Cotorapo Merezorire. — Not being fully satisfied of the mineralogical character of the epecimens sent us from Colorado by Mr. Smith, we eubmitted them to Prof. co whe has seat ue the following note: “ One of the specimens you eent to me Ew, unmistakably, a fragment of meteoric iron, having a peculiar characteristic crystallizatioe, which is not often visible until a polished surface has heen etched with nitric acid. In this specimen, however, the fracture aloue develnpes the crystalline figures, and in a most marked degree. It was this unusual appearance, and the oxydized surface, which very naturally led you to douht its simple metallic character. T'he tragmeet ts doubtless from the same meteorite eoticed by Professor Shepard in the Journal of Science. He notes its siuilarity to the celebrated meteorite of Arva. It contains grains of schreibersite—a hard mineral which somewhat resembles magnetic pyrites. The other small fragment sent appears to he a detached nodule of the echreibersite, hut this cannot he affirmed positively withont further examication.” Quartz Mrvers’ Incomes.—Jules Fricot, s Nevada quartz miner, gives his income for 1865 as $182,511. ‘Ibis is the largest tax retorned in California. ‘he eext largest is that of Jamee P.
