It seems , however , that the fracture was made at the isthmus itself , so that the whole peninsula has become an island . '' `` A strange destiny is ours , Lieutenant , '' said Mrs Barnett . `` Others return from their travels to add new districts to geographical maps , but we shall have to efface the supposed peninsula of Victoria ! '' The next day , July 18th , the sky was very clear , and at ten o'clock in the morning Hobson obtained a satisfactory altitude of the sun , and , comparing it with that of the observation of the day before , he ascertained exactly the longitude in which they were . The island was then in 157 ° 37 ' longitude west from Greenwich . The latitude obtained the day before at noon almost immediately after the eclipse was , as we know , 73 ° 7 ' 20 '' north . The spot was looked out on the map in the presence of Mrs Barnett and Sergeant Long .
