This is a series of documents of correspondence and testimonials reflecting the activities of Brian Houghton Hodgson in the period 1836-1848. Hodgson and his wives were keen collectors of letters and statements that reflected well upon the work in which he was involved.

Letter from Dr Clarke Abel to Brian Houghton Hodgson. Abel apologises for appearing indifferent to Hodgson's researches and will now put forward Hodgson's observations to the Physical Committee with any thoughts that occur to him and suggest the animal is named Antelope Hodgsonii, so the scientific community may know to whom they are indebted for knowledge of the species. He asks whether Hodgson knows anything of its feeding methods in the wild. He writes that Wallich (Nathaniel Wallich, Superintendent Botanic Garden, Calcutta) has sent him two porcupine skins and asks whether Hodgson knows anything of their habits. He also asks about a French half caste boy whom he has engaged, whether he will be admitted into Nepal. He asks how thrives the rhinoceros? Abel regrets to have to inform Hodgson that most of the skins Hodgson sent are in poor condition. He is keen to obtain meteorological reports from different parts of India and wonders whether Hodgson has any. Handwritten, 3 sides, dated 5 December 1825.

Letter from Dr Clarke Abel to Brian Houghton Hodgson. He writes, in case Hodgson has not seen the Government Gazette, to send a copy of the report of the Physical Committee by which Hodgson will see how largely the Committee is indebted to his communications. Hodgson's antelope is an interesting animal in many respects and Abel asks for more information on him. Abel has received the skins that Hodgson sent and intends to make some of them the contents of a Paper. He also thanks Hodgson for samples of minerals and a Bhotan Grammar. He asks in what conditions the specimens were found and whether Hodgson knows anything about a Chinese stone often used as ornament. Abel is submitting some of Hodgson's work to the Calcutta Scientific Journal. He asks that Hodgson will guide Louis Francois to the animals he should study. He hopes that Hodgson may some time come to Calcutta. Handwritten, 3 sides, dated 18 February 1826.
