On the preparation of paper to exhibit a thermal spectrum.
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?
JH concerned not so much that a few copies of the print of JH's portrait may have been sold, but that the plate itself may have been stolen and sold. Seems relieved to know that the plate was left with the printer, not the engraver. Asks RS to make an inquiry with the printer.
Needs the name of the print seller from whom JH's cousin bought the copy of the print of JH's portrait, so RS can learn how many copies are available. RS will then know whether to 'treat with [the printer] as an honest man or a rogue.'
