  Produced by James Simmons. This file was produced from page images at the Internet Archive. Transcriber's Note This book was transcribed from scans of the original found at the Internet Archive. I have rotated some images. The caption for Figure 20 was illegible in the scanned pages so I used a description from a paragraph that referred to it.
