Letter, from Basil Hall to Sir John Herschel, dated at Feistritz near Graz Autograph letter signed by sender. Found his recent stay at the remote German castle very restful. Gives details of a large flight of crows and compares it to nebulae. Cure for sore throats. Hopes the South Easters do not disturb him. Intends spending the winter in Paris. Hopes that John Frederick William Herschel is preparing a two volume work on his scientific experiences. 24 April 1835
