TRANSCRIBER'S NOTE:

Obvious typographical errors in punctuation and spelling have been corrected without comment. One example of an obvious typographical error is on page 109 where the word "utterred" was changed to "uttered" in the phrase: "... he uttered a piercing cry...."

In addition to obvious errors the following changes have been made:

1. Page 376: The phrase "as early in 1773" was changed to "as early as 1773".

2. Page 119: "cocoa" was changed to "coca" in the phrase, "... opium, betel, hasheesh, and coca...."

3. Page 209: "Aureditated" was changed to "Accredited" to reflect the correct title of Jarvis' book: "Accredited Ghost Stories".

4. Page 211: "Aured." was changed to "Accred." in the phrase, "Accred. Ghost Stories".

5. Page 234: "aids" was changed to "aides" in the phrase, "General d'Espagne roused his aides...."

6. On the ad page, the illustration of a hand symbol has been replaced with "-->".

The spelling of most proper names has been left unchanged with the following exceptions:
