Clowes. Stanford-street TO THE KING. SIR, Your Majesty having been graciously pleased to permit an experiment before you at Hampton-court, of a small model of my engine described in the following treatise, and at that time to show a seeming satisfaction of the power and use of it; and having most graciously enabled me, by your royal assent to a patent and act of parliament, to pursue and perfect the same. By which your royal encouragement, it being now fully completed, and put in practice in your dominions with that repeated success and applause, that it is not to be doubted but it will be of universal benefit and use to all your Majesty’s subjects. Of whom, your Majesty being the universal patron and father, all arts and inventions that may promote their good and advantage, seem to lay a just and natural claim to your Majesty’s sacred protection. It is upon this consideration I am encouraged, with a profound respect, to throw this performance of mine, with the author, at your Majesty’s royal feet, most humbly beseeching your Majesty, that, as it had birth in your Majesty’s auspicious reign, you will vouchsafe to perpetuate it to future ages by the sanction of your royal approbation, which is the utmost ambition of, May it please your Majesty, Your Majesty’s most humble, most loyal, and most obedient Subject, THOMAS SAVERY. TO THE ROYAL SOCIETY. At the request of some of your members, at the weekly meeting, at Gresham-college, June the 14th, 1699, I had the honour to work a small model of my engine before you, and you were pleased to approve of it. Since which I have met with great difficulties and expense, to instruct handicraft artificers to form my engine according to my design; but my workmen, after so much experience, are become such masters of the thing, that they oblige themselves to deliver what engines they make me exactly tight and fit for service, and as such I dare warrant them to any body that has occasion for them.
