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. Illustrations which split paragraphs were moved to rejoin
them and in some cases, moved to the end of the section. To match the
other volumes in this series, the list for the placement of images was
positioned after the Table of Contents. "M. Allemand" probably should
have been "M. Allamand" a Swiss-Dutch natural philosopher (1713-1787)
that is reported to have contributed to Buffon's _Histoire Naturelle_.
This was left unchanged.
