A guide shows a suffocated dog to two tourists at the Cave of Dogs near Naples.
On the left, two local men suspend an asphyxiated dog in the lake to make it revive it.
This was when the dog experiments started taking place.
Some of the famous tourists who saw this experiment included Goethe, Alexandre Dumas and Mark Twain.
The dog dies in a minute and a halfa chicken instantly.
And then they don’t either.
The stranger that ventures to sleep there takes a permanent contract.
I longed to see this grotto.
We reached the grotto at about three in the afternoon, and proceeded at once to make the experiments.
But now, an important difficulty presented itself.
We had no dog.
The spectacle of the cave fell into disuse once Lake Agnano was drained in 1870.
The cave no longer attracts tourist as it did in earlier times.
The cave as it appears today.
