This species of Iulus was able to sustain a longer submersion in fresh-water, without apparently any injurious effects.
It is probable that while the percentage of submersion in moving water hardly appears to affect the result, yet prolonged contact with wet sand, sea-weed, or clinging shell-fish may do so.

Now, no combination of causes has been imagined which has not involvedsubmersion during long periods, and subsequent elevation for periods of longer or shorter duration.
The whole scope of animated Nature, the evolution of animals, was suddenly arrested in that part of our hemisphere over which these gigantic convulsions spread, followed by the brief but sudden submersion of entire continents.

Guerard quotes a case happening in 1774, in which there wassubmersion for an hour with subsequent recovery; but there hardly seems sufficient evidence of this.
In all these exhibitions all sorts of artificial means are used to make the submersion appear long.
There is a case in French literature, apparently well authenticated, in which submersion for six minutes was followed by subsequent recovery.

There have been individuals who gave exhibitions of prolonged submersion in large glass aquariums, placed in full view of the audience.
Then for the first time I realise the wonderful sense of security that the possibility of such a rapid submersion gives.
The emergency air valves are opened, the compressed air hisses out of the tanks--the submersion valves sing in all their scales.
When the desired depth is reached, which I can tell at once from the depth gauge, further sinking is prevented by the simple means of making the boat lighter again through pumping out the superfluous water from the submersion tanks.
In order to accelerate the ascent compressed air is forced into one of the submersion tanks.
For this test the crew all took up their submerging stations, the submersion tanks were slowly opened and the boat flooded with just sufficient water to make her float, the conning-tower hatch still remaining above the surface.
