Has received, through AG, a letter on Dionaea [from W. M. Canby] which has greatly interested him. CD asks AG to question his correspondent on whether it catches large or small insects.

Mary Treat will observe Drosera filiformis.

JDH writes to Asa Gray about his work on Pinus, including the nomenclature & synonymy of various species, including P. edulis, P. fremontia, P. llaveana, P. cembroides, P. perryana, P. chihuahuana, P. tuberculata, P. insignis & P. torreyaan. He has begun working on Oaks & finds them even more confusing. JDH has received Gray's letter of 4 June & bag of Torreya seeds. Mentions a Wardian Case of Sikkim Rhododendrons, [part of the letter following this mention is missing]. JDH refers to some RBG Kew staff & mentions that he pays his wife £100 per annum for working 4, 4 hour, days a week. JDH has been elected the new President of the Royal Society over Spottiswoode & the Duke of Devonshire. JDH has reservations about Gray's plans to employ a German Professor, he suggests an American or Swiss man would be better. William Thiselton-Dyer would not take the job as Professor, he has been offered lucrative positions abroad before but is determined to stay in Britain. The following day JDH will go to Cheshire to visit Mr Tollemache, who is an intimate friend of William Gladstone & previously brought Gladstone to visit RBG Kew.
