Pièce 16 - Letter from Augustus De Morgan

1 folded sheet

41 Chalcot Villas, Adelaide Road NW - Has two points to make: 1: the drinking song is Ptolemaic ['this bottle's the sun of our table, how the bottle revolves round the table"] and recalls the Duke of Sussex singing it at a dinner party in 1826. 2: Barrow's method is pretty but does not show the full merit of Peter Metius' [Adriaan Anthonisz'] result. Explains why he thinks the phrasing of 1620 indicates that he did not publish and will give him the reference from his son Adrian Metius' book; will look further at Barrow: "I am not sure that Barrow is not reasoning in, as well as on, a circle".
