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. 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.
