St. Andrews LB III 71, 72 (C: RS:HS 7.295)
Summary:

Would like to know the degree of sensibility to heat of JH's paper. The paper of W. H. F. Talbot is useless for his purpose as only violet heat affects it. Did JH use a flint glass prism for his spectrum experiments? Has he ever used photography to show the impression of polarization and diffraction?
