In that Etheric Region, in that Fourth Dimension, live the Elemental creatures of Nature, and this is something that we should understand deeply. To such creatures we will give the name of Elementals, in fact because they live in the elements.

You know my dear friend, that the fire is inhabited by Elementals creatures; you understand that the air is also densely inhabited by that class of creatures and that the water and the earth, are inhabited by those same Elementals.

The creatures of the fire, from the oldest times, were known by the name of Salamanders; the Elementals of the air are designated with the name of Sylphs; the beings of the water are called Undines, Nereids, Sirens, etc., etc.; creatures that live between the rocks of the earth have been baptized with the name of Pygmies, Gnomes, etc. It is clear that the form of these creatures varies very much.

The creatures of the fire are thin and dry, very similar to the cricket, although of much bigger size.

The creatures of the air seem small very beautiful children with rosy faces like the dawn.

The Elementals of the water have diverse forms; some seem to be ineffable ladies, happy between the waves of the immense sea, others have the form of siren-fish, with the head of a woman, and lastly there are Undines that play with the clouds or live in the lakes and rivers that flow along their rocky channels.

The Gnomes of the earth, the Pygmies, appear to be old men with their long white beards and ceremonious continent. They live normally in the mines of the earth or look after the treasures that are hidden somewhere in the earth.

All these Elementals of the Nature are useful in the great creation; some encourage the fire; others impel the air forming the winds; still others encourages the waters; and others work in the alchemy of the metals inside the bowel of the earth.
