Minor typos were corrected. A web search shows that the anchorless Footnote on page 139 appears to reference the quoted text on page 140. Therefore, the Footnote was placed after the quoted text. On page 174, Footnote 36 referred twice to Figure 8 and to a "Microscopic slice" as Figure 61 (which does not exist). It is assumed the intent was to refer to Figures 7, 7a, 8 and 59 and has been altered to point to those figures. The caption for Fig. 7 also refers to "Fig. 61, p. 310" and has been updated to "Fig. 59, p. 237".
