About five o'clock in the evening
A flight of sea-swallows rested on the Nautilus . It was a species of the Sterna nilotica , peculiar to Egypt ; its beak is black , head grey and pointed , the eye surrounded by white spots , the back , wings , and tail of a greyish colour , the belly and throat white , and claws red . They also took some dozen of Nile ducks , a wild bird of high flavour , its throat and upper part of the head white with black spots . About five o'clock in the evening we sighted to the north the Cape of Ras-Mohammed . This cape forms the extremity of Arabia Petraea , comprised between the Gulf of Suez and the Gulf of Acabah . The Nautilus penetrated into the Straits of Jubal , which leads to the Gulf of Suez . I distinctly saw a high mountain , towering between the two gulfs of Ras-Mohammed .
