Memoire sur les cors des pieds.

The first publication on podiatry, a pamphlet of 19, [1] pp. informally issued by Rousselot to promote his practice. Because of the non-standard title page without mention of place, publisher or date, the pamphlet seems to have been intended to have been given away by the author. The date of publication was assigned by the BnF from the Permission de police at this link. Incidentally, the first name of the author remains unknown. (Thanks to Alexandre Piffault for this reference.)
