Transcriber's Note This text does not refer to epidemic cholera. The term "cholera morbus" was used in the 19th and early 20th centuries to describe both non-epidemic cholera and gastrointestinal diseases that mimicked cholera. The term "cholera morbus" is found in older references but is not in current scientific use. The condition "cholera morbus" is now referred to as "acute gastroenteritis." Spelling variations and inconsistencies have been retained to match the original text. Only such cases which strongly indicated the presence of inadvertent typographical error have been corrected; a detailed list of these corrections can be found at the end of this text. This ebook consists of two separate parts. The first from 1831 ("LETTERS ON THE CHOLERA MORBUS.") contains Letters I-X; and the second from 1832 ("LETTERS ON THE CHOLERA MORBUS, &c. &c. &c.") contains Letters I-III and a Postscript. Transcriber's Notes at the end of the text refer to "Pt_1" and "Pt_2" for ease of navigation. LETTERS ON THE CHOLERA MORBUS. CONTAINING AMPLE EVIDENCE THAT THIS DISEASE, UNDER WHATEVER NAME KNOWN, CANNOT BE TRANSMITTED FROM THE PERSONS OF THOSE LABOURING UNDER IT TO OTHER INDIVIDUALS, BY CONTACT--THROUGH THE MEDIUM OF INANIMATE SUBSTANCES--OR THROUGH THE MEDIUM OF THE ATMOSPHERE; AND THAT ALL RESTRICTIONS, BY CORDONS AND QUARANTINE REGULATIONS, ARE, AS FAR AS REGARDS THIS DISEASE, NOT MERELY USELESS, BUT HIGHLY INJURIOUS TO THE COMMUNITY. _By a Professional Man of Thirty Years experience, in various parts of the World._ LONDON: NICHOLS AND SONS, PRINTERS, EARL'S COURT, CRANBOURN STREET LEICESTER SQUARE. 1831. The first series of these Letters, consisting of five, appeared in the months of September and October of the present year; five others, written in a more popular form, were inserted in a Newspaper from time to time, in the course of this month:--a few additions and alterations, preparatory to their appearance in the shape of a pamphlet, have been made. If, at a moment like the present, they prove in any manner useful to the public, the writer will feel great satisfaction. November 26th, 1831.
