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.
Your kindness in countenancing this invention in its first appearance in the world, gives me hopes the usefulness of it will make it more acceptable to your honourable Society, as they are the most proper judges of what advantage it may be to mankind. And it would be ungrateful in me not to make use of this opportunity to return you my most humble and hearty thanks for the honour and favour you did me in approving my design, and publishing it to the world,* which shall be always acknowledged by
Your most obliged
and most humble Servant,
THOMAS SAVERY.
