Google books at its worst

Apropos of Google Books, this example is really one of the weirdest examples I have seen on Google Books. In fact, the above clip looks almost psychedelic :-)

Unfortunately, as a scan it is absolutely useless, so this is not the way to gain access to Johann Christoph Pohl's 1732 Diss. de hominibus post mortem sanguisugis, vulgo sic dictis Vampyren. By the way, you can find a couple of old posts referring to this book.

I have removed the illustration because of an update to this Google Book, see the comment to this post.
