Pearsall and J.T. Saunders. They recommended her for an MSc, as the interview revealed her insufficient knowledge of phytoplankton. While at Wray Castle she also supervised work on the construction of the equipment, designed by her father, for the FBA’s retirement in 1962.

Jenkin (1902-1994) and the earliest days of the FBA's laboratory at Wray Castle’, by J.W.G. Lund and E.B. Monaghan, Freshwater Forum Vol. 13, 2000. In the introduction the authors state that their original intention was to write a brief article on the earliest days of the FBA's laboratory at Wray Castle. It was to be based on the manuscript material described in this catalogue but, the authors explain: 'It became clear that there were inconsistencies and published statements about Penelope's work and career, as well as in some statements in FBA Annual Reports. Further, the realisation that apparently there was no account of her scientific career led to the production of this article, written with special reference to her work at Wray Castle’. unpublished between certain A facts large archive repositories The material described in this section was used by the authors in the preparation of the article and documents their wide-ranging research to establish the of Jenkin's early career. part comprises their correspondence with universities and organisations at which she worked, including significant correspondence with of Cambridge (B.1-B.2).

The work at Wicken Fen was eventually published by Jenkin as a paper ‘Temperature, hydrochemistry, and plankton in Wicken Brickpits, 1930-1931. A year's survey of two alkaline, dimictic ponds directed by the late J.T. Saunders, from the Zoological Laboratory, Cambridge’, Hydrobiologia 97, 1982. For various reasons (see the off-print of the paper in C.11), the work was not published in Saunders’ lifetime. In the 1970s Jenkin heard of new research being carried out at one of the Wicken brickpits and, realising the historical value of the original studies, prepared the records for publication.
