In considering these minuter points, we must never 

 lose sight of the extraordinary perseverance shown by 

 the Marquis throughout a long life, in conducting and 

 varying his experimental inquiries. It was the one 

 pursuit of a studious life-time, the heaviest source of 

 expenditure in his private disbursements. Perhaps we 

 should be very much under the mark in saying that he 

 must have expended above a hundred thousand pounds 

 in experiments alone ; which would be represented by 

 nearly ten times that amount in our day. And not only 

 was this outlay very great, but he had for above thirty-

 engaged on his models and on practical trials of his 

 variously constructed inventions. 



The Act for his Water-commanding Engine received 

 the Eoyal assent in June, 1663, and the same year he 

 published his &quot; Century of Inventions&quot; (as here re

 pendious Water-commanding Engine, invented by the 

 Eight Honourable (and deservedly to be praised and 

 admired) Edward Somerset, Lord Marquess of Worcester, 

 and by his Lordship himself presented to His most 

 Excellent Majesty, Charles the Second, our most 

 gracious Sovereign.&quot; See Appendix C.

 with means for giving publicity to the formation of a 

 public company for carrying out the great design on a 

 sufficiently large and remunerative scale. The author, 

 or editor, was James Eollock, who here flourishes in a 

 poetical vein, observing, u After the Act of Parliament, 

 there is here set down a Latin Elogium, and an English
