JDH thanks Sir William Turner-Thiselton [WTTD] for finding time to look over the proofs of the BOTANICAL MAGAZINE. After 30 years as editor & 10 years prior to that helping his father with it JDH can be careless. His mind is currently focused on orchids. JDH will try to arrange with the publisher of the magazine, Reeves, to send the lithographs a month in advance so they can be reviewed properly. He notes that errors have also appeared in the BULLETIN. JDH did not think [James Edward Tierney] Aitchison's drawing of Gastrodia was worth publishing but Aitchison did accompany it with an explanation & an anatomist should look at his specimens preserved in spirits. JDH hopes WTTD & Harriet Thiselton-Dyer (nee Hooker) will enjoy their time in Switzerland. An annotation signed D.O. [Daniel Oliver] has been added to the letter stating first that Ed[?] Brown [Nicholas Edward Brown?] would look at the specimens of Gastrodia & later adding that he has examined them himself & found no evidence that they are parasitic themselves, but one of the pseudobulbs was infected by a rhizomorphoid growth, which needs to be investigated.
