176to him by me. Mr. Rochette's receipt is dated August 6. I had planned to leaveParis a few days later, but a slight case of Diarrhea and a fever kept me in beduntil yesterday.The envelope in which the "Program of Courses at the PreparatorySchool" was sent to me constitutes my record that I paid 35 fr. 2 s. to coverpostage; it is included with this letter.As for the article 167 for local periodicals concerning the courses at thePreparatory School: the one I prepared is fairly extensive, in keeping with theprogram. The editors of "se Annales d'Industrie Francais et exteriel", "Journalde l'Economique Central de l'Industrie" /perhaps they are re-evaluating?/refused to place my article in their magazine, stating that once the Institute iscompletely organized, they will gladly publicize its various departments intheir periodical. Mr. Blanqui, 168 a professor of the School of Commerce, madebrief mention of it in one of the issues of "Revue Nationale", under the heading"On fournit l'Ecole Politechnique". I translated practically the whole programfor Mr. Julienne, 169 the editor od "Revue Encyclopedique", and he promisedthat he would include a rather complete article about our school in one of thefuture issues of his ―Revue‖.I wish to thank you, dear sir, for the kind promise that you will receivemy books.
