Other than two possible typographical errors listed below, [the title and verso (second) page] specifies the pages are 305-338; but the first numbered page (the third one) is numbered "309". The content provider examined the text at page breaks and looked for evidence of a missing leaf; but found none. So, this appears to be a printer's error in the pagination as the numbering sequence otherwise follows the normal format for these scientific texts. Therefore, the numbering was changed in the descriptions to read "... pp. 307-338, ..."
