Yes. Unfortunately, in that brief section, Empress's source doesn't summarize the evidence from its own footnotes very well.
Empress's source gives a footnote for this sentence:
"In 1835 Michael Chandler brought several mummies to Kirtland that aroused great excitement among the Latter-day Saints"
to:
H. Donl Peterson,
The Story of the Book of Abraham: Mummies, Manuscripts, and Mormonism (Salt Lake City: Deseret Book, 1995)
Here's how Peterson describes it (still another secondary source, but more detailed and closer to primary sources):
Peterson goes on to discuss the variations in primary sources at length, quoting several extensively.
I'm having trouble linking directly to where that section starts in Peterson's book, because there are no page numbers, but click
here and use the search box at the left to search for any phrase in the above passage, like "Professor Anthon could," and it'll take you to the section and you can read more, including the quotes from primary sources.
The next sentence in Empress's source is this:
"Smith too took note of these objects from antiquity. Initially attracted by his native curiosity, Smith soon realized the significance of the ancient artifacts. Upon examining some of the writing on the papyri accompanying the mummies, Joseph noticed some resemblance to those characters on the plates from which he translated the Book of Mormon."
And it's footnoted to here:
"Letter of Oliver Cowdery to William Frye, December 22, 1835 in
Latter-day Saints' Messenger and Advocate 2, No. 3, 235."
You can read Cowdery's letter
at this link (scroll down about halfway).
Cowdery's letter says:
Based on all the above, I'd say that my summary:
is actually a more accurate summary of the footnotes in Empress's source, than the way Empress's source summarized them:
