Three letters, 1869-1874, to James Kenward, FSA ('Elfynydd'), writer and poet, from H. B. Biden of Nottingham and London. They describe in detail walks and climbs in Snowdonia, South Wales and the Lake District, and include notes and comments on flora, geology, local guides and lodgings, the death of [John Williams] ab Ithel, Llandanwg church, co. Merioneth, the effects on the landscape of industrial and other development, guidebooks to Wales, Kenward's For Cambria: themes in verse and prose (London, 1868), and Oriel: a study in Eighteen Hundred and Seventy (London, 1871), and Biden's own publishing problems.

A volume marked in pencil 'No. 2. 1807' containing Llysieuaeth Cymreig; 'sef enwau Blagur o bob rhyw...' by [Hugh Davies], being a list similar to that printed in his Welsh Botanology (1813), pp. 153-247.
The following note has been pasted inside the cover: 'Mem.dum Febry 24th 1807 9pm - I have just now finished collating this No. 2 with No. 1, & I think I may pronounce them both in perfect concord with each other. H. D.'. The catalogue is written on the recto of each folio, with some notes in pencil facing. There are also some loose notes, one written on the back of a letter from J. G., Llanfair. At the reverse end are notes 'from Scudamore' headed 'Action of Tests on mineral waters'.

The file comprises a card index referring mainly to places of natural history interest, with a brief description of each and notes on visitor access, bibliographic and reference sources, acknowledgements, places to visit and notes on the author's indexing system, and a separate gazetteer consisting of notes, information leaflets and press cuttings mostly relating to historical sites in Wales, with subsections on national nature reserves, the wildlife, plants and history of Harlech and botanical sites from the Nature Conservancy Council inventory, 1954-1986.

The section comprises loose, handwritten and typed notes, notebook, binders, substantial correspondence, photographs, vegetation samples, circulars, press cuttings, maps, loose printed articles, offprints and information leaflets, accumulated during work in natural history and conservation. The material is indicative of Condry's dedicated and detailed approach to research concerning plants, birds, animals and their different habitats. It is obvious that some of the information which he gathered represented an extension of his personal interests and was used for the compilation of books and articles. -- The main subjects comprise botany, ecology, geology, zoology and the work of other naturalists, such as Evan Price Evans, Mary Richards and Evan Roberts. Regular correspondents include Peter Benoit, E. H. T. Bible, Arthur Chater, Dafydd Davies, Evan Price Evans, Jack Grasse, Dewi Jones, Derek Ratcliffe, Mary Richards, Richard H. Roberts, Morrey Salmon, H. R. H. Vaughan and Irene Vaughan.

Notebooks, each containing entries, often sparse, of a varied nature. They reflect the wide range of interests displayed throughout J. Lloyd Williams's papers, but mainly relate to music. The subjects include the history of Welsh music, folk music, Y Cerddor and the National Council of Music, his own compositions and memoirs, broadcasting and education. Entries relating to botany are also included, especially in items numbered 23-28.

The group consists of the scientific papers of J. Lloyd Williams, reflecting his interest and vocation in the field of botany, comprising correspondence, 1892-1942; diaries, 1871-1920; field notes, 1887-1934; botanical terms, [1890x1940]; and lectures, [1905x1937].
