During the visit of the Duke and Duchess of York in 1924 Coryndon was not looking well. Noticing his grey sheen, Dutton asked what was wrong, to be told, 'I believe I am going to have twins.' In fact, he was having trouble with his pancreas. J. Langton Gilks, director of medical services, visited Coryndon in bed one morning but was not unduly alarmed. Dr P.A. Clearkin visited shortly afterwards, was horrified at what he saw and urged immediate admission to hospital. But this was delayed until the evening even though Coryndon was unconscious, because the Chief Justice could not be found to swear in the Acting Governor. Dr H.H.V. Welch, resident surgeon at the European hospital, a drug addict who had been MO at Wajir before the war, operated and found acute haemorrhagic pancreatitis from which Coryndon could not be saved. He died within a few hours and Welch submitted his resignation on health grounds, which was accepted. In fact no surgeon could have saved Coryndon, though Welch later tried to blame his death on the anaesthetic Clearkin had administered, claiming that the Governor's heart could not stand the operation at such a height as Nairobi's.
