Letter from J [John] Herschel, Brompton Barracks, to 'Bella' [Isabella Herschel] He cannot think that Bella admires the photographs, which he describes. He comments on their letter-writing. He wants clearer instructions: he is to send back the stereoscope pictures but he asks about others. He thanks Alick [Alexander Stewart Herschel] and Pankhurst for carefully packed fruit. 17 September 1857
