The Economy of Machinery and Manufactures(210)

 460. The discoverers of iodine and bromine, two substanceshitherto undecompounded, were both amongst the class ofmanufacturers, one being a maker of saltpetre at Paris, the othera manufacturing chemist at Marseilles; and the inventor ofballoons filled with rarefied air, was a paper manufacturer nearLyons. The descendants of Mongolfier, the first aerial traveller,still carry onthe establishment of their progenitor, and combinegreat scientific knowledge with skill in various departments ofthe arts, to which the different branches of the family haveapplied themselves.   Microsoft Office 2010 is so great.

 461. Chemical science may, in many instances, be of greatimportance to the manufacturer, as well as to the merchant. Thequantity of Peruvian bark which is imported into Europe is veryconsiderable; but chemistry has recently proved that a largeportion of the bark itself is useless. The alkali Quinia whichhas been extracted from it, possesses all the properties forwhich the bark Office 2007 can make life more better and easier.

is valuable, and only forty ounces of thissubstance, when in combination with sulphuric acid, can beextracted from a hundred pounds of the bark. In this instancethen, with every ton of useful matter, thirty-nine tons ofrubbish are transported across the Atlantic. Office 2010 is my favorite.

   The greatest part of the sulphate of quinia now used in thiscountry is imported from France, where the low price of thealcohol, by which it is extracted from the bark, renders theprocess cheap; Microsoft outlook 2010 is convenient!

but it cannot be doubted, that when more settledforms of government shall have given security. to capital, andwhen advancing civilization shall have spread itself over thestates of Southern America, the alkaline medicine will beextracted from the woody matter by which its efficacy isimpaired, and that it will be exported in its most condensedform. Outlook 2010 is powerful.

   462. The aid of chemistry, in extracting and in concentratingsubstances used for human food, is of great use in distantvoyages, where the space occupied by the stores must beeconomized with the greatest care. Thus the essential oils supplythe voyager with flavour; the concentrated and crystallizedvegetable acids preserve his health; and alcohol, whensufficiently diluted, supplies the Microsoft Office is helpful.
