After thirty years of labor and fruitless experiments, suddenly received unexpected aid from a discovery made asif for his special use. Discovery of the Diamond Iridium Point, and its Application to Gold Pens. After a multitude of experiments, and about the Year 1833,Mr. Hawkins learned that the celebrated English philosopher, Dr. Wollas-ton, had sent some pieces of Rhodium and some particles of the nativealloy of Osmium and Iridium, to Mr. Robinson, manufacturer of PubyPens, in London, requesting him to make some Pens with each a while, Mr. Pobinson sent Dr. Wollaston a few Pens with pointsmade of the Phodium, but sent back the Iridium, saying that it was Too Hardto be ground or wrought into figure for Pen points. This informationstimulated fresh experiments upon this material, for if it was too hard . SELECTING AND PUTTING ON THE DIAMOND POINTS. This is done by placing a number of blanks in a row on a strip of wood made forthat purpose. The diamond points being carefully selected, a small pencil brush isdipped into liquid borax and with it the points are picked up and set into the workman uses a microscope to enable him to place the points properly. Whenthis is done, the blank is sent to the next man, who fixes the points permanently : 54 to be ground or wrought into shape, it must be, thought Mr. Hawkins,exceedingly durable in use—the very object for which so much moneyand time had been expended. He supposed that diamond dust must abrade the Iridium, althoughit might be slowly, if he gave great speed to the grinding this view Mr. Hawkins fitted up a lathe capable of giving tenthousand revolutions a minute to the mandril; and on this a lap oftwo inches in diamete
