vessels on those principles as an infringement on my rights. As tothe mechanism, I have thought it sufficient to give only one mode ofcombining steam boats for passengers, for merchandize, and forferries, in each of which sails are used as an aid to the engine.(Signed by)“ RoBEeRT FuLTON.Witnessed by(Signed)“ JoHn R.

Mr. Fulton’s second specification is little more than a recapitula-tion of the first, and his claims are to a great extent similar. Itcommences—

“I, Robert Fulton,&c. give the following description of my inven-tions and discoveries for construeting boats or vessels which are tobe navigated by the power of steam engines, believing myself to bethe original inventor and discoverer of the following combinations.To obtain the power for driving the boat, I make use of Watt andBoulton’s steam engine,(for the particulars of which he refers to anEnglish work, the‘ Repertory of Arts,’ vol. vi.) or any other steamengine of equal power, my claim to invention not extending to thesteam engine, but to the proportioning, combining, and applying itin such a manner to a boat or vessel of such dimensions as to driveher to a certainty more than 4 miles an hour in still water.

«“ After having-determined the length, width, and draught of waterof the boat, the details of my patent, dated February 11, 1809, willshow the mode for ascertaining her total resistance while running1, 2, 3, 4, 5, or 6 miles an hour in still water; also, the mode forproportioning the power of the engine, the velocity of the piston, anddiameter of the water wheels, with the velocity of their peripheryand the size of each of their propellers, to overcome any given resist-ance of boat while running 1, 2, 3, 4, 5, or 6 miles an hour in still

water.“ Having been the first to demonstrate the superior advantage of a
