All obvious typographical errors were corrected. Where several variant
spellings were used, the most prevalent version was use to standardize
them. All illustration headers were standardized to display "_Engraved
for Barr's Buffon._" above each group and the captions were also
standardized. The illustration captions were arranged in ascending
numbers. Where paragraphs were split by illustrations, they were
rejoined. To match the other volumes in this series, the list for the
placement of images was positioned after the Table of Contents.
