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. Although the original printed version capitalized the first word (or words) of the opening paragraph, here the first letter only was capitalized (unless it was a person's name). Callitrix (for green monkey) should probably have been Callithrix which is a genus of New World monkeys whereas Callitrix is a genus of coniferous trees. This was left as printed.
