The three American editions I discovered in 2012 were those of 1810 (New York), 1828 and 1830 (Boston). Not having access to any of these online, I suggested at that time, that “it seems most likely that they are all reprints of no.2—the 1793 edition.”

Since writing the above, I have acquired a copy of The Devil in Love that was printed in Boston in 1828.

As you can see above, this edition has a charming frontispiece of “Biondetta Playing On The Harp”; and as you can see below, the Boston text matches—as I suspected it would—no.2 in my previous post, the 1793 edition. This edition starts “At five and twenty I was a Captain of the Guards in the service of the King of Naples, and lived in gay society …”

The two Boston editions are somewhat similar in size and length, suggesting one may be a reprint of the other. It is likely that Peaslee's the Boston edition is itself a reprint of Van Winkle's New York edition, but this is something I will only be able to establish in the unlikely event that I end up with a copy to compare my Boston edition to.

Below is my updated list of editions of The Devil in Love. Since 2011, three of the early editions have been added to Google Books, so I have added links to these. I have also passed on my copy of Biondetta, or the Enamoured Spirit, which illustrates my previous post, to Monash University, and have updated the holdings accordingly.
