Transcriber's Note
Where tables or images split them, the text was moved to rejoin paragraphs. The [List of Publications] before the article was moved down to rejoin the portion after the end of the article.
[Table 6] re-arranged due to use of vertically printed text.
[Page 451] may have a typo "...wide range of error arising from insufficiently small samples..." should probably have been "...large samples..." (emphasis added here). This was left as is.
