"What for?"

"To know what countries the thirty-seventh parallel crosses."

"Nothing easier," replied Paganel; "I need not even disturb myself to tell you."

"Leaving America, the thirty-seventh parallel crosses the Atlantic."

"Good."

"It strikes Tristan d'Acunha Island."

"Well?"

"It passes two degrees to the south of the Cape of Good Hope."
