Transcriber's note: This file was proofed, using a text-to-speech reader, against the hard copy 2nd. edition published in 1819. No attempt has been made to change the text of any of the quoted verse to reflect later editors' amendments. Italics are indicated thus. The footnotes are serially numbered from the first to the last Lecture, unlike in the original.
