Letter, from Hans Christian Oersted to Sir John Herschel, dated at Copenhagen Autograph letter signed by sender. Has not heard from him for a long time or his letter was not delivered and the unrest in Europe has not encouraged him to write letters. Sends articles, also part of a book, which he has been trying to get published by an English publisher. Would like the advice of John Frederick William Herschel on this effort. 29 August 1849
