My lord the duke wrote to me the other day to warn me that certain spies had got into this island to kill me; but up to the present I have not found out any except a certain doctor who receives a salary in this town for killing all the governors that come here; he is called Doctor Pedro Recio, and is from Tirteafuera; so you see what a name he has to make me dread dying under his hands. This doctor says of himself that he does not cure diseases when there are any, but prevents them coming, and the medicines he uses are diet and more diet until he brings one down to bare bones; as if leanness was not worse than fever.
