Ten prints of six different shots of landscape and vegetation, including a plant specimen in a laboratory. Three of the shots are labelled in green ink 'Fig.44', 'Fig.66', and 'Fig.67', presumably for reproduction in a publication. 'Fig.66' corresponds to glass plate negative F100 and 'Fig.67' to F27. The other prints do not appear to have matching negatives. All are unlabelled and undated.
Unlabelled bundle of prints, mostly depicting the effect of frost on leaves. Some are duplicates. Three of the shots correspond to glass plate negatives 6, 8, 9, and 10 in the 'Frost' section.
Nine assorted prints, in envelope labelled 'Prints of Daddy's experiments with flowers'. Only some of the photographs depict flowers. All but one of the prints corresponds to a glass plate negative, namely: F7; F20; F105; Sense 1; and unclassified 11. In some cases there is more than one copy printed.
Planting of marram grass to stop erosion by wind in dunes. Possibly taken at Scolt Head Island, Norfolk. (Note in one of RHY's children's hands, with question mark, on the small envelope in which these prints were originally stored.) These prints correspond to glass plate negatives G31-G37, which were unlabelled.
Modern prints from RHY's negatives of his trip to Italy and Switzerland in 1902-3. Many of the prints correspondence to glass plate negatives. RHY's numbering has been retained where known.
Original prints taken on RHY's trip to Malaysia in 1899-1900. Glass plate negatives are held of some of the shots. The titles of the photographs are transcribed from RHY's labels, though some prints are unlabelled and all are undated.
These prints were stored in a Kodak wallet labelled 'Cambridge Fens 1904'. The glass plate negatives are held for all but two of them. Although the wallet is labelled 1904, some of the negatives were dated July 1908. Prints have been assigned the same reference number as their corresponding negative, and the description from the negative envelope has been used, as none of the prints was labelled.
These plates were not individually labelled or numbered, but were in boxes marked 'Unclassified'.
These plates were not labelled or numbered, but were simply in a box marked 'Sense organs'.
Photographs of salt marsh terrain at various stages of development and its flora taken in the Dovey salt marsh area, Ynyslas, and Glandyfi in the summer of 1914. Also photographs of salt marsh drawings, undated, some unlabelled and undated negatives, and some marked Borth negatives, dated 1925 and not individually labelled.
