Letter from C [Charles] Pritchard, to Sir John [Frederick William Herschel] Pritchard gives thanks for Herschel's kind remembrance and he will re-read the essays. He send regards to Lady Herschel. He apologises for 'an outpouring of spirit from one who now has none but God to speak to in the solitude of confidence' [referring to the death of his first wife, Emily Pritchard, née Newton (1815-1857)]. 16 May 1857
