Jules SOURY (1842-1915), philosopher and historian of neuroscience at the Sorbonne, theorist of racism and anti-Semitism. Autograph letter signed to Eugène Fasquelle. 1 p. in-8. October 4, 1904. Violent anti-Semitic diatribe against Dreyfus. "All my previous public statements remain invariable.

With an autograph sending card. "I believe it is a courtesy to you [...] to send you, my principal publisher, a copy of my political will on the affair you were pleased to speak to me about this morning, a copy of which is in the hands of my great friend General Mercier [...]".
