WITH NOTES. 4U3 



terested in detecting and exposing unjust assumptions 

 of being a true and first inventor. 



Savery claimed perfect independence of the Marquis 

 of Worcester, and promulgated a story to parallel that 

 of the pot-lid, usually related in reference to his prede 

 cessor s invention, while (as is pretended) he was a pri 

 soner in the Tower. Let us now compare certain dates 

 and circumstances to see how far they favour Dr. Des- 

 aguliers charge. 



On the 25th of July, 1698, Thomas Savery, Gen 

 tleman, had granted to him a 14 years patent for 

 &quot; A new Invention for raising of Water and occasioning 

 motion to all sorts of Mill Work by the impellent force 

 of fire.&quot; 



Within six months afterwards, on the 21st of January, 

 1699, died the only son and heir of the Marquis of 

 Worcester, Henry Duke of Beaufort, at 70 years of 

 age. 



Within three months after his Grace s decease 

 Savery had a Bill brought into the House of Lords, 

 which, on the 6th of April, was reported to the House 

 of Commons, and passed on the 25th of the same 

 month. This private Act extended the patent privi 

 lege over 21 years further, making 35 years. 



On the 14th of June following, it is stated in the 

 Royal Society s Transactions, u Mr. Savery entertained 

 the Society with shewing the model of his engine for 

 raising water by the help of fire.&quot; (See page 485.) 



Dr. Hook was then living, but died on the 3rd of 

 March, 1702. Above 38 years had elapsed since 

 his visit to Kaltoff, to see the engine at Vauxhall ; and 

 he could have spoken to the merits of Savery s engine, 

 as compared with what he had earlier seen, had his age 

 and health permitted, or his inclination prompted him 

 so to act.
