See Phil.Mag., 1832, 1: 75 for an account of Milne-Edwards's Friday Evening Discourse on 8 June 1832 on "Recent important improvements in lithotrity by Baron Heurteloup". The Lit.Gaz., 16 June 1832, p.378, noted the Discourse, but declined to give details on this "painfully interesting" subject on the grounds it was only fit to appear in the medical journals.
