Preface to the Second Edition

   The present second edition is, in the main, a faithful reprint of the first. Typographical errors have been corrected, a few stylistic blemishes eliminated, and a few short paragraphs that contain only repetitions struck out.

   The third book, which presented quite unforeseen difficulties, is now also nearly ready in manuscript. If my health holds out it will be ready for press this autumn.
