UnknownLetter from the Countess Vernède de Corneillan of 46 (ancien) rue de Rivoli au coin de la rue Castiglione, Paris to [Charles] Babbage, 10 Sep 1854. 'Monsieur Babbage m'a fait passer la lettre que vous avez eu la bonté de lui écrire au sujet d'inventions de M. [Philippe] de Girard … Je prends la liberté de vous récrire a çe sujet, car cette affaire est d'une haute gravité pour notre famille … Vous dites …que le "moyens de M. de Girard sont ingénieux mais que le même effet a été produit par des moyens plus simples, et tellement analogues qu'il me serait difficile de prendre un brevet"'. Saying that if this sentence concerns 'les greniers à blé', she would like to ask certain questions: (i) whether the process analogous to that of Girard is patented in England; (ii) under what name; (iii) at what date and since when; (iv) what are the differences that make it simpler and what are the things analogous to it? Excuses her importunity on the grounds of the matter's important to the memory of her uncle.
