A Note on the Text:
The text is that of the first and only known edition published by Edward Lloyd in 52 numbers between March/April 1843 and March 1844 in the classic 8-page per number style, authored anonymously, but generally assumed to be by James Malcolm Rymer, and found in the British Library and online at Nineteenth Century Collections Online. The OCR, editing, and proofreading were performed by myself and reflects as exact as possible the original publication with no modernization of spelling or punctuation.
