Send a message to the person who requested a photo of the grave monument of John Murray with the following comment:
As an amateur historian of oceanography. Following a visit to Edinburgh last month, where I saw the house in which John Murray spent the last 15 years of his life (Challenger Lodge, Granton), I've begun a study of his time in Edinburgh after returning from the Challenger Expedition (1876). There is no full biography of this important figure. So the immediate reason for my request is to enable me to read the inscription on his tombstone.
