Fully agree with the other 1 star reviews--this reprint (from "FP Pubs", or Filiquarian Publishing) has been very poorly scanned, with many pages blurry, or often with one whole edge (or even one half) of the text cut off. Includes nice images of the scanner's hand. This was purchased for a college library, but it's not worth putting on the shelf. Turns out there is a fine Penguin paperback available of this, but it oddly doesn't appear when you search for "Lyell Principles of Geology" on Amazon.
