"In one hour each man consumes the oxygen contained in 100 liters of air, hence during twenty-four hours the oxygen contained in 2,400 liters. Therefore, we must look for the multiple of 2,400 liters of air that gives us the amount found in the Nautilus."
Cada hombre gasta en una hora el oxígeno contenido en cien litros de aire, o sea, en veinticuatro horas, el oxígeno contenido en dos mil cuatrocientos litros.
