About the year 1729, my subscribers explained my pretensions to the lords of the Admiralty, and the lord Torrington declared my claim just to the reward assigned, in the last clause of the act, to those who should make discoveries conducive to the perfection of the art of sailing.  This he pressed with so much warmth, that the commissioners agreed to lay my tables before Sir Isaac Newton, who excused himself, by reason of his age, from a regular examination:  but when he was informed that I held the variation at London to be still increasing; which he and the other philosophers, his pupils, thought to be then stationary, and on the point of regression, he declared that he believed my system visionary.  I did not much murmur to be for a time overborne by that mighty name, even when I believed that the name only was against me:  and I have lived till I am able to produce, in my favour, the testimony of time, the inflexible enemy of false hypotheses; the only testimony which it becomes human understanding to oppose to the authority of Newton.

My notions have, indeed, been since treated with equal superciliousness by those who have not the same title to confidence of decision; men who, though, perhaps, very learned in their own studies, have had little acquaintance with mine.  Yet even this may be borne far better than the petulance of boys, whom I have seen shoot up into philosophers by experiments which I have long since made and neglected, and by improvements which I have so long transferred into my ordinary practice, that I cannot remember when I was without them.

When Sir Isaac Newton had declined the office assigned him, it was given to Mr. Molineux, one of the commissioners of the Admiralty, who engaged in it with no great inclination to favour me; but, however, thought one of the instruments, which, to confirm my own opinion, and to confute Mr. Whiston’s, I had exhibited to the Admiralty, so curious or useful, that he surreptitiously copied it on paper, and clandestinely endeavoured to have it imitated by a workman for his own use.

This treatment naturally produced remonstrances and altercations, which, indeed, did not continue long, for Mr. Molineux died soon afterwards; and my proposals were for a time forgotten.

I will not, however, accuse him of designing to condemn me, without a trial; for he demanded a portion of my tables to be tried in a voyage to America, which I then thought I had reason to refuse him, not yet knowing how difficult it was to obtain, on any terms, an actual examination.

About this time the theory of Dr. Halley was the chief subject of mathematical conversation; and though I could not but consider him as too much a rival to be appealed to as a judge, yet his reputation determined me to solicit his acquaintance and hazard his opinion.  I was introduced to him by Mr. Lowthorp and Dr. Desaguliers, and put my tables into his hands; which, after having had them about twenty days under consideration, he returned in the presence of the learned Mr. Machin, and many other skilful men, with an entreaty that I would publish them speedily; for I should do infinite service to mankind.
