Journal December 1836
p7–8“Gave me an account of Dahmiron's book, Jouffroi's – Dahmiron had given him new light about Spinoza.”
Fuller, Margaret. "Journal December 1836." Houghton Library, Harvard University; MS Am 1086; Box 3.
Inferred Fuller names 'Damiron's book' without specifying the title; context (discussion of Spinoza, philosophical conversation with Channing) points to his Essai sur l'Histoire de la Philosophie en France au dix-neuvième siècle (1828) or Cours de philosophie (1831–36), which contained sections on Spinoza and was the leading French textbook in philosophy at this period.
