It’s the same source. Various people and sites claim that the book (American Annual Register) is quoting John Quincy Adams, but I could not find his name after searching through a lot of the book and certainly not in Chapter X where the quote comes from. The author or editor of the book has the name Blunt. If John Quincy Adam wrote the quoted words, it should say that in the book somewhere or there should be another book by John Quincy Adams that they are copied from. Maybe you can find this proof.
