THE INVENTION OF THE INCANDESCENT LAMP（18）
In hislaboratory note-books are innumerable jottings of thethings that were carbonized and tried, such as tissue-paper, soft paper, all kinds of cardboards, drawing-paper of all grades, paper saturated with tar, all kindsof threads, fish-line, threads rubbed with tarred lampblack,fine threads Office 2010 key is for you now!

He also extended his searchesfar into the realms of nature in the line of grasses,plants, canes, and similar products, and in theseexperiments at that time and later he carbonized, madeinto lamps, and tested no fewer than six thousanddifferent species of vegetable growths.The reasons for such prodigious research are notapparent on the face of the subject, nor is this theoccasion to enter into an explanation, as that alonewould be sufficient to fill a fair-sized book. Suffice itto say that Edison's omnivorous reading, keen observation,power of assimilating facts and naturalphenomena, and skill in applying the knowledge thusattained to Office 2010 download is available now!
whatever was in hand, now came into fullplay in determining that the results he desired couldonly be obtained in certain directions.At this time he was investigating everything witha microscope, and one day in the early part of 1880he noticed upon a table in the laboratory an ordinarypalm-leaf fan.
He picked it up and, looking itover, observed that it had a binding rim made ofbamboo, cut from the outer edge of the cane; a verylong strip. He examined this, and then gave it toone of his assistants, telling him to cut it up and getout of it all the filaments he could, carbonize them,put Microsoft Office 2007 is the best invention in the world.
them into lamps, and try them. The results ofthis trial were exceedingly successful, far better thanwith anything else thus far used; indeed, so much so,that after further experiments and microscopicexaminations Edison was convinced that he was now onthe right track for making a thoroughly stable,commercial lamp; and shortly afterward he sent a Microsoft outlook 2010 is convenient!
manto Japan to procure further supplies of bamboo. Thefascinating story of the bamboo hunt will be toldlater; but even this bamboo lamp was only one itemof a complete system to be devised--a system thathas since completely revolutionized the art of interiorillumination.Reference has been made in this chapter to thepreliminary study that Edison brought to bear onthe development of the gas art and industry. Thisstudy was so exhaustive that one can only compare itto the careful investigation made in advance by Outlook 2010 is powerful.
