'In 1690 he invented a contrivance for rowing ships in a calm by means of two paddle-wheels, one at each side of the 

 vessel, worked by a capstan placed between. William III. thought highly of it, but, although Savery demonstrated its 

 practicability by fitting it to a small yacht, official jealousy prevented its adoption by the navy. He was obliged to 

 content himself by publishing an account [the abovej of his invention . . . This treatise contained a vehement protest 

 against the treatment accorded him in official circles.' D. N. B.
