Letter from Sidney J Wyard, Walney Island, Walney Island, Lancaster, to A V Hill Informs Hill that he had done work in the Physical Chemistry Lab at Cambridge until being called up - that Norrish's appeal for his release was declined on the grounds that his war work was too important, though he was engaged in 'digging holes' and not using his scientific training. Appeals to Hill for help. 3 February 1943
