It is at night, especially when the moon is gibbous and waning, that I see the thing. I tried morphine; but the drug has given only transient surcease, and has drawn me into its clutches as a hopeless slave. So now I am going to end matters, having written a full account for the information or the contemptuous amusement of my fellow-men. Often I ask myself if it could not all have been a pure phantasm—a mere freak of fever as I lay sun-stricken and raving in the open boat after my escape from the German man-of-war.
