Context

“What are you writing? What are you doing? How about Houssaye? etc. As for myself, I take a river bath every day. I swim like a triton. My health never has been better. My spirits are good, and I am full of hope. When one is in good health he should store up a reserve of courage, in order to meet disappointments in the future. They will come, alas! I believe that in the Rue Richer there is a photographer who sells views of Algiers. If you could find me a view of Medragen (the tomb of the Numidian kings) , near Algiers, and send it to me, I should be very grateful.” source
