Diving to great depths was only possible following extensive experiments conducted by Professor Picard with the Batyscaphe off Dakar. The first experiment showed the FNRS II Batyscaphe reaching a depth of 1,500 metres in a non-embarked dive and, despite being watertight, having suffered enormously from the swell. Two years later, the Bathyscaphe FNRS III, built in Toulon, dived off Dakar and reached a depth of 4050 m two hours later. It carried two men and a camera which, through a porthole and with the help of projectors, gives us the first images of another world.
