Letter from C [Charles] Pritchard, Euston Square Hotel, to Sir John [Frederick William] Herschel, Collingwood, Hawkshurst, Kent He notes the odd address, saying that while the two boys [Herschel's sons?] and a hundred more are away from school, he is going to get strength, waiting for a train to Kendal. He has read Herschel's piece in 'The Athenaeum'. He remembers how words on the new planet thrilled through him. 'Nothing is more joyous & elevating than the anticipation by a long calculation of a result'. He remarks that this has been [George Biddell] Airy's triumph. He wishes that Herschel had a Grove battery so that he could find the thing he was looking for in light. Pritchard gives messages for the Herschel boys and to Lady Herschel. In a postscript he wishes [Michael] Faraday could explain the effect on a drop of water of clean glass recently broken, by potash. 'As to [William Robert] Grove he wants a head informed - this is very bold & I hope for him not true'. no date 'Saturday' [3 October 1846. Postmark 5 October]
