JDH compliments Sir William Turner Thiselton-Dyer [WTTD] on his paper on 'Spontaneous Generation & Evolution' & hopes that it is a prelude to further research into the chemistry of vegetation as JDH believes there is no better man to do it. JDH is currently reading John Tyndall's paper 'On the Actions of Rays of High Refrangibility upon Gaseous Matter' in PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY OF LONDON & he is struck by Tyndall's remarks on the decomposition of carbonic acid, by solar rays, in the leaves of plants. JDH says that he had thought about this independently & believes it would make a good research subject. Has heard that Dr P[ercival] Wright it going to Algeria for the winter. JDH hopes that he has left the key to the [Trinity College] Herbarium for them.
The Joseph Dalton Hooker Collection
The Joseph Dalton Hooker Correspondence Project at Kew is making available online the personal and scientific correspondence of the botanist and explorer Sir Joseph Dalton Hooker (1817–1911), Director of the Royal Botanic Gardens’ Kew from 1865-1885. The project was conceived by staff of The University of Sussex and Kew's Library, Art and Archive department and began as a partnership between Kew and the University of Sussex's Centre for World Environmental History. It has been made possible by support from the Stevenson Family Charitable Trust. Letter summaries can be searched through Ɛpsilon, with links to images and transcriptions at the project site at Kew (https://www.kew.org/explore-our-collections/correspondence-collections/joseph-hooker-collections).
