Transcriber Note
Minor typos corrected. [Listing] of "The International Scientific Series" was split between the front and end of book but are here moved to the end. The list was also reformatted. Figures [12], [60], [77], [79], and [80] were originaly printed as negative images. Here the positive is shown with a link to the original views. The captions for the map key in [Figure 58] were reformatted into a table. [Figure 41] was relocated as it followed [Figure 42] in the printed version.
