Letter, from Thomas John Hussey to Sir John Herschel, dated at Chislehurst Autograph letter signed by sender. Dawson and Thomas John Hussey think it would be a good idea to republish William Herschel's papers together with a biographical memoir. Has John Frederick William Herschel thought of doing this; if not would he allow Dawson to do it? Has not heard if the foreigners engaged on the Berlin maps have relinquished their portions. The Munich instrument is a most vicious instrument. 10 September 1830
