A separately published offprint, in the form of a letter to Mr Nicholson, Author of the Philosophical Journal, originally published in that journal in December, 1804.

Although firstly a maker of telescopes and other astronomical instruments, the author describes how he has been making pendulums for twenty years, "...and I own the subject is still agreeable to me, being yet unencumbered with patents, the reason of which no doubt is, that the few wanted hold out no prospect of gain."
