Letter, from William Empson to Sir John Herschel, dated at 29 George St., Hanover Square Autograph letter signed by sender. [George] Peacock asks for more time for his review. Enough science in vol. 2 to tempt John Frederick William Herschel. John Frederick William Herschel should be the new editor for Brown. Will send Alexander von Humboldt a copy of the review unless he thinks it should come from the author and not the editors. Returns to Haileybury on Thursday. 16 January 1848
