I have designed this book not as a guide, but as supplementary to a guide. The best of guide-books—even that of Murray or of Gsell-Fels—leaves a whole world of thought and knowledge untouched, being indeed of necessity so full of detail that broad, general views can scarcely be obtained from it.

In this work detail has been sacrificed without hesitation. I have omitted reference to a few well-known places, usually because I could add nothing to the information given in the handbooks, but in one or two cases because the considerations which they raised lay too far from the thread of my discourse.

I have thrown together in the form of an appendix such hints and suggestions as seemed likely to assist anyone who desires wider information than I have given.
