Exchanging further information on several aspects of the photographic process [see RH's 1840-4-15].
Hopes that his paper does not anticipate any of RH's work; will share with the R.S.L. any of RH's results. Laments that he is unable to fix the spectral colors on photographic paper. Asks if RH has studied the bromines.
