In 1660 the House of Lords appointed a committee to consider of the validity of a patent granted to the Marquis of Worcester in prejudice to the Peers, upon the first intimation of which his Lordship sent a messenger to the committee then sitting, stating his willingness to surrender it, and it was shortly afterwards presented to the House by his son Lord Herbert.
In 1663 appeared the first edition of the noble Author's Century of Inventions, and on the 3d of April in the same year, a bill was brought in for granting to him and his successors the whole of the profits that might arise from the use of an engine, described in the last article in the Century.[4]
Of the merits of the Century of Inventions as a literary composition but little can with justice be said; whether, however, as a scientific production, it deserves the character that has been given of it by men more celebrated for their literary attainments, than for scientific knowledge, the reader, after a perusal of the work, will readily determine.[5]
The Marquis likewise published a work entitled "An Exact and true Definition of the most stupendous Water-commanding Engine, invented by the Right Honourable (and deservedly to be praised and admired) Edward Somerset Lord Marquis of Worcester, and by his Lordship himself presented to his most excellent Majesty Charles II., our most gracious Sovereign." This was published in a small quarto volume consisting of only twenty-two pages, and is now become extremely rare.
His lordship survived the publication of this work but two years; as he died in retirement near London upon the third of April 1667. His remains were conveyed with funeral solemnity to the cemetery of the Beaufort family in Ragland church; where he was interred on Friday the nineteenth of the same month, near the body of his grandfather, Edward Earl of Worcester. The coffin was placed in an arched stone vault, with the following inscription on a brass plate:
"Depositum Illustrissimi Principis Edwardi Marchionis et Comitis Wigorniæ, Comitis de Glamorgan, Baronis Herbert de Raglan, Chepstow et Gower, nec non serenissimo nuper Domino Regi Carolo primo, Southwalliæ locum tenentis: qui obiit apud Lond. tertio die Aprilis, An. Dom. MDCLXVII."
