Hodgson used much of his time in both Nepal and Darjeeling in research, wanting to discover and understand about the architecture, languages, ethnography, religion, zoology and botany. He collected specimens and manuscripts, and had many drawings made, which he donated to many collections throughout Europe. He was also politically involved during his Residency in Nepal, and also later in England, when he continued to show an active interest in the Indian subcontinent, particularly regarding trade and vernacular education. These Personal Papers reflect these interests and are a record of much of his activity - Hodgson and his wives seemed to have a need to record all his successes. He was also a keen annotator of material, so that most of the printed material also bears his handwritten comments.

The series consists of 38 letters from Joseph Dalton Hooker to Brian Houghton Hodgson. They have been organised mainly according to a previous listing made of the material, approximately by date.

Letter from Joseph Hooker to Brian Houghton Hodgson. He apologises for the paper he is using as all his writing paper has been used up on the accompanying journal which will explain to Hodgson what he has been doing. He writes of his surprise at the geology of the Himalayas and that he has collected rhododendrons and seeds for his father. He is thinking of staying a day or two at Pemiongchi. He writes about [Chamamaya] being a splendid fellow. There is a list of his food requirements and he asks Hodgson to send [Burchess] and Co. if he thinks appropriate. Handwritten, 1 piece, undated [1848-1850].

Letter from Joseph Hooker to Brian Houghton Hodgson. He writes that he had last written to Hodgson on his way to meet the Rajah. They have left [bamsong] after Christmas after a final interview with the Dewan who had been extremely attentive. The Rajah had told Archibald Campbell that Hooker could start for [Lachen] in spring. Hooker had informed the Dewan that he was certainly going. Hooker does not foresee much difficulty, Campbell having given the Dewan a warning. Hooker writes that Campbell had insisted on one who speaks Hindustani and the only one was the heir apparent's servant. Hooker continues to report on the negotiations between Campbell and the Rajah. He then talks about the geology and vegetation of the area he is travelling through. With accompanying envelope. Handwritten, 4 sides, dated 28 December 1848.
