vice, and after experi-menting, he hit upon the so-called sim and planet gear-ing, and henceforth this was used on his rotary enginesuntil the time for the expiration of Picards patent,after which the simpler and more satisfactory crankand fly-wheel were adopted. In the meantime. Watt had associated himself with abusiness partner named Boulton, imder the firm nameof Boulton and Watt. In 1776 a special act of legisla-tion extending the term of Watts original patent for aperiod of twenty-five years had been secured. All in-fringements were vigorously prosecuted, and the in-ventor, it is gratifying to reflect, shared fully in themonetary proceeds that accrued from his invention. Notwithstanding the early recognition of the pos-sibility of securing rotary motion with Watts per-fected Newcomen engine, it was long before the fullpossibilities of the appHcation of this principle wererealized, even by the most practical of machinists.Watt himself apparently appreciated the possibilities (100)

watts rotative engine. TKe lower figure shows the earliest type of mechanism through which Wattapplied his engine to other uses than that of pumping. The so-called sun-and-planetgearing, through which rotary motion was attained, is seen at the lower right-handcorner of the figure. The upper figure shows a later and much improved type ofthe Watt engine, in which the sun-and-planet gearing has been supplanted by asimple crank. CAPTIVE MOLECULES no more fully than the others, as the use of his famousengines Beelzebub and Old Bess in the estab-lishment of Boulton and Watt amply testifies. It ap-pears that Boulton had been an extensive manufacturerof ornamental metal articles. To drive his machineryat Soho he employed two large water wheels, twenty-four feet in diameter and six feet wide. These sulB&cedfor his purpose under ordinary conditions, but in dryweather from six to ten horses were required to aid indriving the machinery. When Watts perfected enginewas available, however, this
