TitleManuscript, 'Contributions to the chemistry of chlorophyll. No. II' by [Henry] Edward Schunck
Date1886
DescriptionSchunck writes: 'Considering the intimate though as yet little understood connexion between chlorophyll and the carbon dioxide of the atmosphere, it seemed to me that it might be of interest to ascertain whether compounds of phyllocyanin, similar to those previously described, could be obtained, in which the organic or other acid should be replaced by carbonic acid. On passing a current of carbon dioxide through a solution of phyllocyanin in absolute alcohol holding a quantity of freshly precipitated hydrated ferrous oxide in suspension, no combination took place, the phyllocyanin remaining unchanged, though the current of gas was passed through the liquid for a considerable time.'

Annotations in pencil and ink. Includes one diagram of the absorption spectra of phyllocyanin and its principle compounds and derivatives.
