My Dear Sir,
I write you very hurriedly to say that I shall be most happy to receive your Paper on the Phenomena of Crystallisation observed with a Microscope <1> or on any other subject.
I hope you will not allow any of your valuable observations to be lost. Even if you dislike publishing them you ought to preserve them in a regular journal of Experiments. <2>
I shall follow your advice in publishing as soon as I can my Observations on the Spectrum; <3> but I must make one expt with the lime light to ascertain the position in artificial light of the extreme line A

2. WHFT, in fact, had kept a series of informal journals since at least 1822. Most are in the Fox Talbot Collection, the British Library, and are listed in H J P Arnold, William Henry Fox Talbot; Pioneer of Photography and Man of Science (London: Hutchinson Benham, Ltd, 1977), pp. 362–363. His two journals most critical to photography were donated to the Science Museum and are now in the NMeM, Bradford; they are reproduced in facsimile and transcribed in Larry J Schaaf, Records of the Dawn of Photography; Talbot’s Notebooks P & Q (Cambridge: Cambridge University Press, 1996). WHFT’s notebooks are an eclectic mix of inspirations, experiments, examples imperfectly recalled, and memoranda to himself. A much more organized series of research experiments is reflected in Herschel’s notebooks preserved in the Science Museum Library; they have yet to be analyzed and collated with Herschel’s surviving notes. Brewster’s notebooks were probably lost in the house fire after his death.
