Browsing: Diary of John Quincy Adams, Volume 2

Mr. Williams gave a public astronomical lecture this afternoon, relating to the different theory's of the planetary System; he gave an account of the Ptolemean, the Tychonic,1 and the Copernican. There was little more than what may be found in most astronomical books; but the lecture was entertaining and was {p. 123} very à propos, as it relates to the public course, and, to the book, which we have just begun to study.

Weather very comfortable.
