You'll have to post pictures of the Webster jar, but let's hope that you didn't overpay.
The book, of course, is 1844, not 1944. You've got some foxing going on, but the book doesn't look bad at all and I don't think you overpaid. As a sidenote, you should put the word "davenport" into E-Bay and search under antiques. The little captain's desks you'll see are also called davenports, supposedly named after an 18th century English sea captain of that name who invented them for use on ships. Whether the story is apocryphal or not, your book would look particuarly good - and apt - displayed on a davenport desk.
P.S. Don't beat yourself up for overpaying, which I'm not yet convinced you've done in any case. Live and learn. It's a jungle out there!
