While it appears that Sarah was likely reading, for volume 2, the William Julius Mickle's translation, 3rd edtiion, London 1798—evidenced by her quoatation on page 33 (here) that references the appropriate page number—it seems, from this page number, that she was not reading the same edition for volume 1. In volume 1 of the 1798 (3rd) edition of Mickle's translation, the footnote she quotes in on page 117, rather than 90. This suggests that she might have been reading two different editions for the different volumes (something that would be likely, given she could have been getting her copies from lending libraries or friends, and that editions of this book seemed to have come all the way from London). Of course, not all the editions have been digitized, and thus we cannot be sure what edition she was reading of volume 1, and can only speculate that she was reading the Lonon 1798 edition of volume 2.
